[0:00] <shiftplusone> gadgetoid, what do you plan to use the board for?
[0:00] <hosler> trigger on down(@clock)
[0:00] <shiftplusone> if it's not a pirate secret.
[0:00] <flexus> the code is really hard to read

[0:01] <gadgetoid> shiftplusone: Not doing anything piratey with FPGAs yet, I think the idea of reflowing one makes us cry!
[0:01] <shiftplusone> heh
[0:01] <gordonDrogon> socket ...
[0:01] <flexus> the altera ide seems to be more understandable
[0:02] * cave (~quassel@gateway/tor-sasl/cave) Quit (Remote host closed the connection)
[0:02] <gadgetoid> I was playing with Retrocade Synth, which is a SID chip and YM-2419 synthesis bonded with ZPUino
[0:03] <shiftplusone> ah
[0:03] <flexus> i'd be interested in fpga but the DA conversion frightens
[0:03] <gadgetoid> And some really, really, really, really basic HDL stuff

[0:35] * tkeemon (~tj@88.247.135.132) Quit (Ping timeout: 245 seconds)
[0:35] <[Saint]> pi-gast-3141: it _should_.
[0:36] * Vutral (~ss@mirbsd/special/Vutral) has joined #raspberrypi
[0:36] <[Saint]> pi-gast-3141: google around for "Huawei e173+debian"
[0:37] <[Saint]> There's nothing raspberrypi-specific here.
[0:37] * gadgetoid (~gadgetoid@customers.shef1.resi.ask4.co.uk) Quit (Quit: gadgetoid)
[0:37] * darkavenger is now known as darkavenger_afk
[0:38] <[Saint]> Most of the information I can dig up at a glance pertains to Ubuntu, but, its all the same at the end of the day and will transfer to debian nicely.
[0:39] <[Saint]> Pro-tip: don't PM people without first asking to do so, I'm just find handling support here, thanks.
[0:39] <pi-gast-3141> sorry
[0:40] <pi-gast-3141> new here
[0:40] <[Saint]> The only thing you should need to pull in is usb_modeswitch
[0:41] <Sonny_Jim> How many many channels of 44KHz/16bit audio could the Pi play at once do you think?
[0:42] <[Saint]> That's...rather vague.
[0:42] <[Saint]> The codec is going to make a HUGE difference to that.
[0:42] * MikeJ1971 (~MikeJ1971@host86-150-84-52.range86-150.btcentralplus.com) Quit (Quit: Bye!)
[0:42] * Bozza (~Bozza@unaffiliated/bozza) Quit (Remote host closed the connection)
[0:42] * Bozza (~Bozza@unaffiliated/bozza) has joined #raspberrypi
[0:42] <Sonny_Jim> Well, just standard WAV
[0:43] <Sonny_Jim> I don't need separate outputs either, just stereo would do fine
[0:43] <pi-gast-3141> @Saint: So tell me the rulz i need to know here.
[0:43] <flexus> its like 320kb
[0:44] <[Saint]> Sonny_Jim: you'll be looking at about 8~12MHz overhead for decoding.
[0:45] <Sonny_Jim> I suppose there is one way to find out and that's to try it
[0:45] * swym (~swym@unaffiliated/swym) has joined #raspberrypi
[0:45] <[Saint]> stock ffmpeg isn't nearly as efficient as Rockbox's heavilt arm optimized implementations, but, the overhead for lossless is _very_ low.
[0:45] <[Saint]> *heavily
[0:45] <Sonny_Jim> Sure, lossless is fine
[0:45] <Sonny_Jim> I'm thinking about replacing the sound board on my pinball table with a Pi
[0:45] <[Saint]> Well...you did say WAV, so, I would hope so.
[0:46] <Sonny_Jim> I think currently it's 4 channels + 1 channel of voice
[0:46] <[Saint]> If lossless isn;t fine, stop using WAV. ;p
[0:46] <Sonny_Jim> Disk space is cheap ;-)
[0:46] <flexus> Sonny_Jim: there is some instruction for pinball pi
[0:46] * Macuser (~textual@unaffiliated/macuser) Quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…)
[0:47] <[Saint]> You'll almost certainly run out of IO bandwidth before you run out of headroom for decoding additional streams.
[0:47] <Sonny_Jim> IO bandwidth?
[0:47] <Sonny_Jim> You mean the interface with the machine?
[0:47] <Sonny_Jim> Runs at 8MHz iirc
[0:47] * foogle (~foogle@gateway/tor-sasl/foogle) Quit (Quit: foogle)
[0:48] <[Saint]> I mean, how much data it can push around on device, and how quickly.
[0:48] <Sonny_Jim> Hmm
[0:48] <Sonny_Jim> So to pull some random specs out the air:
[0:48] <flexus> do you mean this one ? http://www.raspberrypi.org/fireball-pinball-hd/
[0:48] <Sonny_Jim> Yeah, that sucks. Should have used FreeWPC ;-)
[0:49] * Squarepy (~Squarepy@unaffiliated/squarepy) Quit (Quit: Leaving)
[0:49] * utack (~utack@46.114.5.244) has joined #raspberrypi
[0:49] <Sonny_Jim> 5 channels of 44KHz wav, reading an 8MHz 8bit databas via the GPIO
[0:49] <flexus> have to look up wpc
[0:49] <Sonny_Jim> *databus
[0:49] * MagicMystic (cc6c6066@gateway/web/freenode/ip.204.108.96.102) has joined #raspberrypi
[0:50] <[Saint]> The "problem" with lossless, is that while you reduce the CPU time required to decode it, you _vastly_ increase the filesize, and therefore the IO directly.
[0:50] <MagicMystic> anyone every use 'stunnel' with their pi?
[0:50] <Sonny_Jim> I can probably drop the sample rate down to 32KHz
[0:50] <[Saint]> If you wanted as many streams as possible, you might want to settle for a codec that was more expensive to decode, but has a much smaller footprint.
[0:50] <pi-gast-3141> sent the raw data to external decoder chips
[0:50] <MagicMystic> I'm running raspian and can't seem to get the client to connect
[0:51] <MagicMystic> running it on port 443
[0:51] <MagicMystic> can netstat and see it listening...and have the port open on my router...but the client won't connect. any suggestions?
[0:51] <Sonny_Jim> Hmm, I supopse the question should be, do you think it's feasible that I could play 5 channels of 32KHz audio AND read an 8MHz databus on the GPIO at the same time
[0:51] <pi-gast-3141> port 22
[0:51] <[Saint]> MagicMystic: you've seen http://www.raspberrypi.org/forums/viewtopic.php?f=36&t=40389 I assume?
[0:52] <Sonny_Jim> Actually, it's 2MHz the databus on WPC
[0:52] <MagicMystic> [Saint]: yes I have. I am thinking that perhaps it something is haywire with the client (macbook) that is not allowing the handshake to occur
[0:53] <[Saint]> You could just do it yourself with ssh tunnelling.
[0:53] <[Saint]> The Internet has about 17 bajillion guides thereon.
[0:54] <MagicMystic> [Saint]: unforuntately, I work on a network with deep packet inspection and can't run ssh on any port ;-(
[0:54] * Encrypt (~Chuck-nor@AMontsouris-553-1-117-136.w92-151.abo.wanadoo.fr) has joined #raspberrypi
[0:54] <[Saint]> Uuuuugh.
[0:55] <pi-gast-3141> Vpn tunneling?
[0:55] <MagicMystic> so i'm thinking i can ssh on 443 by wrapping it in https
[0:55] <[Saint]> right.
[0:55] <MagicMystic> [Saint]: yes...it sucks being on such a locked down network...
[0:56] <MagicMystic> I'll keep exploring - sure I can get it working - probably just overlooking something minor.
[0:56] <[Saint]> I don't suppose you have a mobile with an unlimited data connection?
[0:56] <[Saint]> That's how I used to get around my grief.
[0:56] <Sonny_Jim> Can you not just run it on port 443? That's what I used to do
[0:56] <Sonny_Jim> Ah reverse tunnel on 443 :-)
[0:56] <Sonny_Jim> That's the ticket
[0:56] <[Saint]> Nowadays I use a WiFi Pineapple.
[0:57] <[Saint]> WiFi Pineapple is designed specifically for network penetration testing, but, it also comes in handy for tunelling out of heavily restricted networks.
[0:57] * Encrypt (~Chuck-nor@AMontsouris-553-1-117-136.w92-151.abo.wanadoo.fr) Quit (Client Quit)
[0:57] <[Saint]> Expensive as almighty Hell, though.
[0:57] <Sonny_Jim> http://www.linuxjournal.com/content/ssh-tunneling-poor-techies-vpn
[0:57] <pi-gast-3141> why is ther dpi in yuor nw?
[0:57] <MagicMystic> [Saint]: yes, but I have to connect to several databases and hate dropping the connection to look at irc or something...
[0:57] <[Saint]> Because some employers are incredibly anal.
[0:58] <MagicMystic> so I don't really like using my cell connection
[0:58] <pi-gast-3141> and what kind of dpi?
[0:58] <[Saint]> MagicMystic: this is my solution these days
[0:58] <MagicMystic> we have to be anal here...very large network with lots of users...
[0:58] <[Saint]> https://wifipineapple.com/
[0:58] <flexus> Sonny_Jim: transfer rate seems to be 12mb write, 18mb read, could be possible
[0:58] <flexus> cant asure you that
[0:58] <[Saint]> expensive, but, you'll NEVER find yourself locked in, or out, of any network again.
[0:59] <MagicMystic> [Saint]: thanks for sharing i'm looking at the page now...
[0:59] <[Saint]> ...even if it happens to be password protected. ;p
[0:59] <[Saint]> It can break WPS in a matter of seconds.
[0:59] <[Saint]> ...not that I'd do that...'cos...illegal...yeah...
[0:59] * harish (~harish@121.121.35.209) Quit (Read error: Connection reset by peer)
[0:59] * [Saint] is a good boy. MmmmHmmm.
[1:00] <[Saint]> A saint, one might say.
[1:00] * harish (~harish@121.121.35.209) has joined #raspberrypi
[1:01] * [Saint] loves his WiFi Pineapple.
[1:01] <MagicMystic> [Saint]: not too expensive $99 right?
[1:01] <[Saint]> The cheapest variant isn't terribly expensive, no.
[1:01] <[Saint]> The Mk 5 with all addons is a bit more than people are willing to pay, though.
[1:02] <[Saint]> I find it invaluable not only for securing my own network and running automated penetration tests, but, also for breaking out of restrictive networks, or breaking in to secured networks.
[1:03] <[Saint]> (with the administrators permissions, of course...yeah...sure)
[1:03] <pi-gast-3141> solutions are not made for problems.
[1:03] <pi-gast-3141> problems are there to fin a solution
[1:03] <pi-gast-3141> thats evolution ^
[1:04] <[Saint]> The first time I tried using it to break WPS I was absolutely _amazed_ at how quickly it could defeat WPS implementations.
[1:04] <[Saint]> I mean, I knew WPS was broken, and I can defeat WPS from home in a matter of minutes.
[1:04] <[Saint]> But, this thing does it in seconds.
[1:05] <[Saint]> And has nowhere near the amount of computing power that I can dedicate to the task from home.
[1:05] <[Saint]> It is designed for penetration testing and network security, but, law enforcement is also using it unofficially to invite themselves into secured networks.
[1:06] <[Saint]> Australia and New Zealand have both been caught using it in the wild. The UK is suspected to, and likely does.
[1:07] <MagicMystic> [Saint]: it is just using freely available linux tools right?
[1:07] <pi-gast-3141> does it suport opencl an 8000 gcn cores?
[1:07] * MoshinWasTaken (~bangboom@173.227.40.62) has joined #raspberrypi
[1:08] <[Saint]> I use mine primarily to ensure that I can always punch a hole through to my home network.
[1:08] <[Saint]> MagicMystic: in part, but there is also a lot of cutom built software on there.
[1:08] <[Saint]> It would be possible to build something very /similar/ from freely available tools, yes.
[1:08] <[Saint]> But perhaps non-trivial to create a system that works as well as this all-in-one package.
[1:09] <[Saint]> You're largely paying for the workmanship and hardware. Which are both excellent.
[1:09] <pi-gast-3141> backtrack
[1:09] <MagicMystic> [Saint]: certainly a nice looking package
[1:10] <[Saint]> It is very well made - and, no, I am in no way affiliated with the company and stand to receive no benefits or commissions by referring anyone to it. :)
[1:11] * Moshin (~bangboom@173.227.40.115) Quit (Ping timeout: 272 seconds)
[1:11] <MagicMystic> [Saint]: :)
[1:11] <pi-gast-3141> why is double percission on nvidia hardware not working so well an on amd?
[1:13] * beet0l (~beet0l@cpe-68-174-87-254.nyc.res.rr.com) Quit (Ping timeout: 240 seconds)
[1:14] <[Saint]> Assuming you mean "on linux", its because the state of the drivers for both is absolutely abysmal.
[1:14] <pi-gast-3141> *lol* my neighbors pass was his dogs name with a few numbers araund
[1:14] <[Saint]> One needs to have a very new, and very popular, crad in order to guarantee even remotely decent driver support in linux.
[1:14] <[Saint]> *card
[1:16] <pi-gast-3141> 2 radeon hd 7950 and a fx 8100
[1:16] <pi-gast-3141> its all u need
[1:16] * MidnighToker (~Toker@unaffiliated/midnightoker) Quit (Ping timeout: 240 seconds)
[1:19] <pi-gast-3141> of course a quick ssd is needed too

[1:25] * MagicMystic (cc6c6066@gateway/web/freenode/ip.204.108.96.102) Quit ()
[1:26] <pi-gast-3141> is there a way to get kde working more efficient on the raspi
[1:28] <CoJaBo> That might be difficult..
[1:29] <pi-gast-3141> maybe with an external ssd
[1:29] <CoJaBo> KDE *needs* pretty decent graphics acceleration to not run horribly..
[1:29] * Bozza (~Bozza@unaffiliated/bozza) Quit (Remote host closed the connection)
[1:29] <CoJaBo> It ran fine on my now-ancient netbook with intel graphics, but the GFX acceleration worked fine there
[1:29] <pi-gast-3141> core is at 500
[1:30] * Bozza (~Bozza@unaffiliated/bozza) has joined #raspberrypi
[1:30] <CoJaBo> Most of what matters is whether desktop compositing works
[1:30] <CoJaBo> Without that, it'll be unusably slow
[1:31] <pi-gast-3141> is there a howto on the net
[1:32] <pi-gast-3141> have to get my english better

[1:42] * flexus (~user@chello062178084053.1.12.vie.surfer.at) Quit (Ping timeout: 250 seconds)
[1:42] <CoJaBo> that will likely still be too slow
[1:42] <CoJaBo> if it's swapping with just KDE, there isn't going to be a way to fix that
[1:42] * snuffeluffegus (~snuff@2001:9b0:10:2104:216:3eff:feb7:f845) has joined #raspberrypi
[1:43] <pi-gast-3141> latecy of hdd
[1:43] <CoJaBo> I think the absolute minimum is 1 GB RAM
[1:43] <CoJaBo> You probably need something other than KDE; KDE isn't meant for very-low-power devices
[1:43] <pi-gast-3141> like banana pi?
[1:44] <CoJaBo> ?
[1:45] * fortytwo (~thomas@who.let.this.bloody.dropbear.in) has joined #raspberrypi
[1:45] <pi-gast-3141> annd other x environments?
[1:47] <pi-gast-3141> the pi is new to me
[1:48] <pi-gast-3141> but an amazing piece of hw
[1:48] <CoJaBo> pi-gast-3141: you want one that's as lightweight as possible
[1:48] <pi-gast-3141> wright
[1:49] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[1:49] <CoJaBo> Raspian uses LXDE iirc
[1:49] <pi-gast-3141> but powerfull enough to work with
[1:49] <Travis> I am running Pidora.
[1:50] <Travis> Speaking of that, I need to get IRC working on it.
[1:50] <ZER0C001> install irssi
[1:50] <Travis> Too late.
[1:50] <Travis> I have HexChat on it
[1:50] <pi-gast-3141> use xchat
[1:50] * KingPin (kingpin@bela.kpsn.org) has joined #raspberrypi
[1:50] <CoJaBo> pi-gast-3141: If you need a more powerful environment, use a computer and SSH into the pi
[1:50] <pi-gast-3141> i do so right now
[1:50] <Travis> HexChat is where Xchat left off.
[1:51] <ZER0C001> I dont use a GUI
[1:51] <ZER0C001> im trying to get RaspPlex up on it
[1:51] <pi-gast-3141> sudo apt-get install xchat i think
[1:52] <ZER0C001> im a big command line guy
[1:52] <CoJaBo> I didn't even have working video-out on mine for the first several weeks.. >_>
[1:53] <pi-gast-3141> yust want to explore its possibilitys
[1:54] <ZER0C001> i plan on replacing all the rokus with raspberry Pis with plex
[1:55] * flexus (~user@chello062178084053.1.12.vie.surfer.at) has joined #raspberrypi
[1:55] <pi-gast-3141> logging on an morer potent system is not what i want to explore
[1:56] <Travis> This is my first crack at talking on my Pi :D
[1:56] <polarburn> hexchat, xchat..... No. irssi. ;)
[1:58] <polarburn> I'm with ZER0C001 on this topic.
[1:58] <pi-gast-3141> what is better on irssi
[1:58] * Datalink (~Datalink@unaffiliated/datalink) has joined #raspberrypi
[1:59] <polarburn> I like being to grab any of my rich devices and open a terminal to one of my jump hosts and open my screen session that has IRSSI running on it.
[1:59] <polarburn> I don't need all the graphical richness of a gui.
[1:59] <ZER0C001> thats handy
[1:59] <ZER0C001> i have yet to use screen for anything but a serial console
[1:59] <polarburn> Nor is a nick list like weechat has needed. Like this channel with 400+ nicks...
[2:00] <polarburn> ZER0C001: Oh, man I likely have hundreds of screen sessions running out in the world right now.
[2:00] <ZER0C001> nice

[2:08] <polarburn> Can open/close my doors from my phone.
[2:09] <pi-gast-3141> yeah ardruino hands up
[2:10] <polarburn> I like the pi much better. I like being able to ssh in and change my perl code on the fly.
[2:10] <pi-gast-3141> wich arduinos do u use
[2:10] <polarburn> I have used all most of them. But I don't have any active projects with them.
[2:11] <polarburn> I have a few network attached data center monitors.
[2:11] <polarburn> But nothing special.

[2:21] <irc_smirk> im doing some web development and would love to upate stuff on my mac and magically the pi is updated as well
[2:21] <irc_smirk> other method i can think of is git
[2:22] <irc_smirk> or setup a filesharing folder some how?
[2:22] <irc_smirk> is that samba?
[2:22] <hybr1d8> How about bittorrent sync or syncthing?
[2:22] <hybr1d8> Then can set a folder to sync automatically between systems
[2:22] <Travis> I forget how to do cross platform file sharing on Fedora :(

[6:06] <linuxmint> lazy_prince, ok, same error. Line edited with init=/bin/sh was definitely saved.
[6:07] <linuxmint> lazy_prince, in terms of mounting. The SD card inserted in the Raspberry Pi B does load up and prompt for username and password, so I assume the SD installed the backed up raspbian.img file correctly.
[6:08] * _BigWings_ (~Thunderbi@modemcable167.12-130-66.mc.videotron.ca) has joined #raspberrypi
[6:08] <lazy_prince> cmdline is usually on /boot but passwd and shadow files are generally on /etc. if / is not mounted, these files may not get updated during passwd change process..
[6:08] <lazy_prince> use mount cmd.. :)
[6:10] <linuxmint> lazy_prince, the flashing cursor where I then enter the command $ passwd pi, appears after [ 3.564609] usb 1-1.3: serialNumber: 00e04c000001.

[6:14] <linuxmint> lazy_prince, ok, I might misunderstand where/what to mount, but I'm inserting the SD card with the edited cmdline.txt file with init=/bin/sh. When the Raspberry Pi loads up and shows the flashing cursor, I type $ mount, but receive error: warning: failed to read mtab.
[6:16] <linuxmint> lazy_prince, do you mean mount on the Raspberry Pi, as I am not sure how to capture the dmesg data that loads on boot from the Raspberry Pi to this working computer, as I can't log into the Raspberry Pi.
[6:17] * mpking (~mpking@184.75.208.122) Quit (Quit: stage left)
[6:17] <lazy_prince> this means that your root partition on your sdcard may be corrupted or is not mounted.. and so the needed files are not accessible for passwd to work properly.. try mmounting root partition manually.. again using mount.. :)
[6:17] <linuxmint> lazy_prince, maybe I'll try another full reinstall of the SD card using the backed up raspbian.img.
[6:18] * Lupinedk is now known as lupinedk
[6:18] <linuxmint> lazy_prince, ok, so I'll put the SC card into this working computer and unmount, then install the backed up raspbian.img. After this, should I then mount?
[6:18] <lazy_prince> probably, that would be the fastest way to recover.. :)
[6:19] <lazy_prince> if your image i proper, then you will be able to login without issues...
[6:19] <linuxmint> lazy_prince, sorry, yes it is fast and workable, but I noticed the install of the backed up raspbian.img file needed the SD card unmounted first on the Mac, whereas Linux installs without the extra unmount command. Maybe I need to then mount the SD card to finish the job or something?
[6:19] <lazy_prince> if you still need to change passwd, use 1 on the cmdline.txt instead on init=/bin/sh
[6:20] * MidnighToker (~Toker@unaffiliated/midnightoker) Quit (Ping timeout: 246 seconds)
[6:20] <linuxmint> lazy_prince, yes that's what I did. I typed in, (space)init=/bin/sh.

[6:21] * \mSg (~mSg@unaffiliated/msg/x-4576342) Quit (Remote host closed the connection)

[11:11] <gordonDrogon> etc.
[11:13] <Sonny_Jim> Apparently it's due to the driver being in an alpha state
[11:13] <Sonny_Jim> So what audio API do rasbian apps normally use, OSS?
[11:14] <gordonDrogon> since pulse doesn't appear to be running by default I'd guess ALSA.

[11:22] <Sonny_Jim> The aim is down the line to replace the sound board on my pinball table with a Pi
[11:22] <Sonny_Jim> The interface to the pinball table is a 8bit databus clocked at 2MHz which I'm hoping I'll be able to hook up to the GPIO
[11:22] <Sonny_Jim> If I can get 5 simultaenous sounds, I think that will be enough

[11:33] <gordonDrogon> that's easy with SDL_Mixer.
[11:36] <gordonDrogon> is the 8-bit interface just to send sound commands from pinball machine to sound board?
[11:37] <gordonDrogon> if-so, capturing that 2MHz clock might be tricky.
[11:38] <Sonny_Jim> Well, there is already a product that does that, whether I can do it with the overhead of playing WAV is another matter
[11:38] <Sonny_Jim> http://www.drpinball.co.uk/dmdextender.htm
[11:41] <Sonny_Jim> I'm off to a pinball show this weekend in Manchester and I'm hoping that Dr Pinball will be there so I can pick his brains about it
[11:42] <gordonDrogon> fascinating.
[11:42] <gordonDrogon> wish I had the space/time/energy to get a pinball machine.
[11:42] <Sonny_Jim> They aren't that cheap any more
[11:42] <Sonny_Jim> My first one cost me less than £400, now you'll be hard pushed to find one for less than £800
[11:43] <gordonDrogon> so DMD is a bus used by a lot of pinball machine to transfer matrix display and sound data by the sound of it.
[11:43] <Sonny_Jim> Yup
[11:43] <Sonny_Jim> The processor is a 2MHz 6809, then theres a databus that daisy chains from the coil driver, sound and DMD driver boards
[11:43] <gordonDrogon> shame he doesn't give more details or the code.
[11:44] <Sonny_Jim> The WPC hardware (Williams Pinball Controller) is fairly well documentated, due to the emulator PinMAME
[11:44] <Sonny_Jim> Also I'm friends with an ex-Williams engineer who has been helping me
[11:45] <Sonny_Jim> Going back to WAV playback, I believe the bottleneck is going to be streaming from the SD card (10-20MB/s?)
[11:45] * D30 (~deo@222.127.13.226) Quit (Quit: D30)

[11:46] <Sonny_Jim> I'll have a look at SDL_Mixer though, thanks
[11:47] <gordonDrogon> sdl_mixer will load them all into RAM for you.
[11:48] <gordonDrogon> optionally it will load mp3, wav, etc. formats too.
[11:48] <Sonny_Jim> So I guess I should have two threads, one reading the databus through the GPIO, another for SDL_Mixer?
[11:49] <gordonDrogon> you might be able to "fire & forget" the sounds.
[11:49] <gordonDrogon> so wait for command - start sound, go back to wait for command.
[11:49] <gordonDrogon> I'm not sure it's 2MHz eithe - I've just seen a note that suggests 70Hz, but that seems too slow to update a display.

[12:43] <Sonny_Jim> Hmm weird
[12:43] <Sonny_Jim> Doesn't seem to be SDL_mixer.h in /usr/include
[12:43] <gordonDrogon> you need to install the -dev
[12:44] <Sonny_Jim> ah
[12:44] <Sonny_Jim> "libsdl1.2-dev is already the newest version" apparently
[12:44] <gordonDrogon> you'll need: libsdl1.2-dev and .. let me check..
[12:45] <Sonny_Jim> It's ok, I got it
[12:45] <gordonDrogon> libsdl-mixer1.2-dev
[12:45] <Sonny_Jim> It's libsdl1.2-mixer-dev
[12:45] <gordonDrogon> ok
[12:45] <Sonny_Jim> ;-)
[12:45] <Sonny_Jim> apt-cache search is handy
[12:46] <gordonDrogon> it's what I use in my RTB interpreter. it seems to work well to load/play samples as well as play my synthesized sounds.

[12:57] <Sonny_Jim> Well, they haven't announced pricing yet, but the rumours are it'll be in that range
[12:57] <Sonny_Jim> There's not that much of a market for it, hence the high price

[13:25] <gordonDrogon> well - the SPI bus can run at 32Mb/sec, so 4MBytes/sec max.
[13:25] <pi-gast-3141> usb ssd better way?
[13:26] <pi-gast-3141> ist there any hack like that with undokumented stuff

[13:30] <Sonny_Jim> Right, so it's possible to do 5 voices of 44KHz WAV
[13:30] <Sonny_Jim> I suppose now I should protoype a bit of GPIO code

[13:37] <gordonDrogon> realitically, exstending the RAM on the Pi isn't possible - but using RAM as program storage might be possible, although it would be easier and probably faster to just use the SD card.
[13:37] <pi-gast-3141> 16 bit adress 32bit data?!?
[13:38] <pi-gast-3141> nobody tried it with s5 and s2
[13:39] <shiftplusone> pi-gast-3141, even with documentation (which isn't public yet), dsi/csi loopback is difficult.
[13:39] <pi-gast-3141> gpio just for control
[13:39] <gordonDrogon> pi-gast-3141, on your Pi, you only have 17 GPIO pins.
[13:40] <pi-gast-3141> but possible but how fast without bottoming out
[13:40] <gordonDrogon> so you could use gpio expander chips, or shift registers & latches, but all that really slows down access to the ram - slower than using SD card.

[13:55] <gordonDrogon> remember the Pi foundations aims were to change the teaching of computing. The Pi itself is just a means to that end.
[13:55] <Sonny_Jim> The fact that businesses have started using it is only a plus imo, means that stock will be around for longer
[13:55] <gordonDrogon> The fact that the Pi has found a huge hobbyist (and commercial!) place is merely a good side-effect.
[13:55] <Sonny_Jim> natch
[13:57] <pi-gast-3141> But when do they make a fully compatible but more performant model to the market

[18:34] <Encrypt> Really?
[18:34] <Encrypt> When the red light is on, the GPU still uses energy?

[18:36] <gordonDrogon> yes. after a halt or powerdown command, you can reboot it by shorting out one of the I2C pins to 0v, or toggle the run input.
[18:36] <Yacou> If I remember good, on the B+, the red LED means there's enough power.
[18:36] * rylinaux (~Ryan@unaffiliated/rylinaux) has joined #raspberrypi

[18:38] <PovAddictW> ohh
[18:38] <gordonDrogon> you can read it in software too - also turn the LED on/off via software if you want.
[18:38] * iamjarvo (~textual@pool-98-115-181-52.phlapa.fios.verizon.net) has joined #raspberrypi
[18:39] <Yacou> You can turn it on/off, but can't hold in one state, right?
[18:40] * YeahRight (~yeahright@5249B7A3.cm-4-2c.dynamic.ziggo.nl) has joined #raspberrypi
[18:40] <gordonDrogon> yes, you can turn it on when the low voltage detector tries to turn it off.
[18:40] <gordonDrogon> I think - let me check..
[18:41] <Yacou> I've tried to turn both led's off, but they re-turn on after.
[18:41] <gordonDrogon> yes, the Pi can drive the led stronger than the power detect chip.
[18:41] * `Nef is now known as `N
[18:42] <PovAddictW> actually
[18:42] <PovAddictW> I tried playing with the ACT LED and the same happened
[18:42] <PovAddictW> the "problem" is that the trigger of the ACT LED is set to mmc0
[18:42] <gordonDrogon> the ACT led needs to be un-wired from the kernel first.
[18:42] <PovAddictW> if you set the trigger to none, you can turn it on and off all you want
[18:43] <gordonDrogon> if you have wiringPi installed, then gpio -g mode 35 out ; gpio -g write 35 0 will turn off the power led.
[18:43] <gordonDrogon> PovAddictW, yes - that's what you should do first.
[18:44] <PovAddictW> capslock key works but doesn't turn on the capslock LED on my USB keyboard; ideas?
[18:44] <gordonDrogon> buy a new keyboard ;-)

You keep track of the 'head' element and you can traverse through the list and add/remove elements as required. If you need to, you can add a 'prev' to go backwards, but meh.

[20:29] <shiftplusone> I am guessing it might be a library issue
[20:29] <e^ipi> I couldn’t get it building on the pi, it’s one of those “no external dependencies!” projects that actually has a hell of a lot of dependencies it just drags their unpatched versions along for the ride
[20:30] <shiftplusone> try ldd or whatever the command is

[20:36] <PovAddictW> so what video player supports GPU acceleration?
[20:36] <PovAddictW> does VLC?
[20:36] <Syliss> i think im going to turn my pi into an irc server today
[20:36] <shiftplusone> PovAddictW, I don't think the version of vlc in rapsbian does, but if you compile it yourself, yes.

[20:39] <`N> freenude lol
[20:39] <Syliss> lol shiftplusone
[20:39] <Syliss> its for my department at work
[20:39] <shiftplusone> ah
[20:39] <Syliss> we want a dedicated server
[20:40] <shiftplusone> I was wondering why anybody would want to run their own irc server, but that makes perfect sense.
[20:41] <Syliss> yeah

[21:45] <Sonny_Jim> gordonDrogon: I forget, but did I ask you earlier if 2MHz on the GPIO pins is feasible with wiringPi?
[21:46] <gordonDrogon> Sonny_Jim, in software - just about, but you have minimal cpu left over and no easy way of accurately timing it - on the output side - for input - maybe, but you're at the mercy of linux & the hardware getting in the way if you're polling for an edge.
[21:47] * Sonny_Jim nods
[21:47] <joachimhs> gordonDrogon: At the moment Im using 8 rechargeable NiMH batteries (they are currently charging), which isn't the optimal solution, but I'm weary of using Lipos with the kids ;)

[22:55] <Sonny_Jim> brian1001: Go right ahead
[22:55] <brian1001> i have this new raspberry pi :) and a new SD card, *without PiFace* but just a 40 Meters CAT5e wire connected to GPIO #7
[22:55] <brian1001> the GPIO port is input
[22:56] <brian1001> and monitors for a button press (the GPIO7 is basically connected to the GND of the RASP)

[22:56] <brian1001> it surprized me but its works great :-) -> without resistor ...
[22:56] <brian1001> for the experts here : would you still connect a resistor ...?
[22:57] <Sonny_Jim> gordonDrogon: The soundboard has a more complicated connection, unfortunately. 8 data lines + clock + r/w + blanking + reset
[22:57] <Sonny_Jim> I might be able to get away with not using the blanking/reset however
[22:58] <gordonDrogon> brian1001, definately. With a 50m cable, it's going to attract all sors of noise on the line.
[22:58] <brian1001> Gordon : btw, i made a very small script using your great GPIO tool again
[22:58] <gordonDrogon> brian1001, at the very least, set the internal pull-up.

[22:59] <gordonDrogon> well if it works, then it works!
[23:00] <brian1001> :))
[23:00] <brian1001> it kept working great hte whole day :)
[23:00] <gordonDrogon> Sonny_Jim, it's capturing the clock that will be that issue. the bi-directional nature may also pose a problem if you need yo level shift, but there is a nice single chip to do that over 8 lines.
[23:00] <Sonny_Jim> I think worst case scenario, I write a kernel driver or stick an mcu in between the Pi and the CPU
[23:02] <Sonny_Jim> I think for prototype/testing purposes I might get away with not having bi-directional, as the worst that happens is that the pinball machine displays "Sound interface error" but will still send out the commands

[23:03] <gordonDrogon> the sound board in that schematic is full of eproms!
[23:03] <gordonDrogon> sure that 8-bit bus in't just carrying 8-bit sound data?

[23:03] <gordonDrogon> or is it the entire sound board you're trying to emulate here?
[23:04] <Sonny_Jim> Nah
[23:05] <Sonny_Jim> The databus just sends 2 byte commands to the sound board, which has it's own CPU/ROM data
[23:05] <Sonny_Jim> It's plausible to emulate the sound board on the Pi (I have PinMAME sources that compile) but I'm not going to bother
[23:06] <Sonny_Jim> Much easier to just record the sounds as WAV and play them back
[23:06] <gordonDrogon> ok
[23:06] <gordonDrogon> these things are positively ancient in their design )-:
[23:06] <Sonny_Jim> Yup
[23:06] <Sonny_Jim> And this was made in 1994
[23:06] <gordonDrogon> although it looks good that they had a common board and interface system.
[23:06] <Sonny_Jim> 2MHz 6809s a go-go
[23:06] <gordonDrogon> they weren't popular CPUs though.

[23:07] <Sonny_Jim> In fact they didn't stop using the 6809 until 1999 with their pinball 2000 platform
[23:07] <Sonny_Jim> In fact, Stern *still* used 6809s well into the 21st century
[23:08] <gordonDrogon> I guess they still had some old programmers who liked them.
[23:08] * Sonny_Jim nods

[23:08] <Sonny_Jim> The cost of retooling for a new platform would be expensive as well
[23:09] <Sonny_Jim> I mean, Stern are still using DMD displays, although they are talking about moving to LCD. They only started using RGB LEDs instead of incandescents last year
[23:09] <gordonDrogon> you could do almost all of it with a couple of arduinos these days. the 'hard' part is the power and mechanicals, really.

[23:10] <Sonny_Jim> Sure, pinball isn't hugely complicated, although writing ball tracking routines is a bit of a headache
[23:10] <Sonny_Jim> ie The machine can only ever best guess as to where the ball is based on switch inputs
[23:10] <gordonDrogon> they track balls?
[23:10] <Sonny_Jim> And some of those switches might break
[23:10] * snuffeluffegus (~snuff@2001:9b0:10:2104:216:3eff:feb7:f845) Quit (Remote host closed the connection)
[23:10] <Sonny_Jim> Sure
[23:10] * gordonDrogon wonders why...
[23:10] * cybr1d (~cybr1d@unaffiliated/cybr1d) has joined #raspberrypi
[23:11] <Sonny_Jim> You need to know when certain things happen
[23:11] <gordonDrogon> but you have sensors/switches for all that, surley?
[23:11] <Sonny_Jim> Game rules are a bit more complicated than "Switch close, add points"
[23:11] <Sonny_Jim> Take a loop, for example
[23:11] <Sonny_Jim> The normal way to detect when a ball has travelled round a loop is to start a timer on the entry switch close
[23:12] <gordonDrogon> !
[23:12] <Sonny_Jim> Then when the ball hits the exit switch, check to see how long that timer has been running
[23:12] <Sonny_Jim> And that's just for one ball, it gets hugely complicated when there's more than one ball flying around
[23:12] <gordonDrogon> so you know how long it took to go round the loop ... why do you need that information?
[23:12] <Sonny_Jim> Because you don't know if the ball has gone halfway round the loop and fallen back down again
[23:13] <gordonDrogon> won't it just trip the entry sensor again?
[23:13] <Sonny_Jim> Yes, but you need that timer to see if it came from the other way
[23:13] <Sonny_Jim> ie left loop or right loop
[23:13] <gordonDrogon> I guess it might be an issue if you expected more than one ball in the loop...
[23:14] <Sonny_Jim> This is just one example, as the mechanisms get more complicated, so does the logic
[23:14] <Sonny_Jim> Everyone thinks it's easier to write pinball code than it is ;-)
[23:14] <gordonDrogon> I'm not seeing any problems right now - however I also have not played a modern pinball machine...
[23:15] <Sonny_Jim> People expect complicated game rules now
[23:15] <Sonny_Jim> Like combo shots, shoot this ramp followed by that ramp etc
[23:16] <gordonDrogon> Hmm.
[23:16] <Sonny_Jim> Or skill shots, launch the ball from the plunger lane and land it in a certain place
[23:16] <Sonny_Jim> EM or electromechanical games had very simple rules, because they used relays and motors

[23:16] <Sonny_Jim> Once they switched to solid state things got a bit more complicated
[23:16] * gordonDrogon nods.
[23:17] <gordonDrogon> I wonder if they use a higher level language for the 6809's.
[23:17] <gordonDrogon> I know there was a good pascal avalable for them as I used it once ...

[23:18] <brian1001> Gordon: if you would have my setup here iwth the long wire , would you (in my case) connect the external resistor betweem the GND and rasp?
[23:19] <brian1001> Gordon: thank you for your good help btw!
[23:19] <Sonny_Jim> Talking to a couple of old pinball devs they were apparently using ASM with lots and lots of macros
[23:21] <gordonDrogon> brian1001, probably not. however the 'danger' is setting the pin to output mode and writing it to 1/high then pushing the button.... a 100Ω resistor wouldn't do any harm though.

[23:42] <brian1001> tried it with the latest raspbian image
[23:42] <gordonDrogon> it might be rsyslog
