**** BEGIN LOGGING AT Sat Oct 20 03:00:03 2012 Oct 20 16:53:39 <_av500_> back Oct 20 17:19:40 front Oct 20 17:37:10 hello Oct 20 17:37:34 im pretty keen on moving to a beagle from arduino Oct 20 17:37:51 <_av500_> you gotta move it move it Oct 20 17:38:24 wish i hadnt bought a mega and ethernet shield Oct 20 17:38:34 could have gotten a lot more with a beagle for the pice Oct 20 17:40:10 i just have one question, how easy is the gpio to use? Oct 20 17:40:18 <_av500_> depends Oct 20 17:40:40 my u;timate goal would be to use objective-c to program it Oct 20 17:41:11 can you elaborate? Oct 20 17:41:18 <_av500_> some even use python Oct 20 17:41:55 some ppl think the pi is better. Oct 20 17:42:21 seems to me the pi is hard to get and i dont wanna use something i cant get in volume Oct 20 17:42:56 <_av500_> some people are wrong Oct 20 17:43:04 <_av500_> but then, both run linux Oct 20 17:43:12 + i kinda like TI since my first comp was a 99/4A Oct 20 17:43:17 draig: if it's for slow gpio, it's just writing text in files in /sys Oct 20 17:43:28 sweet Oct 20 17:43:37 <_av500_> and in both, toggling a gpio is just accessing sysfs Oct 20 17:43:47 i doubt it would be slower than a 16 Mhz duino Oct 20 17:43:48 <_av500_> unless you have strong timing constraints Oct 20 17:43:53 <_av500_> hence it depends Oct 20 17:44:02 draig: ergh, i wouldn't bet on it Oct 20 17:44:12 oh well if you're running with RT priority ... couldb e Oct 20 17:44:25 hmm does it have an spi or i2c bus? Oct 20 17:44:31 sure Oct 20 17:44:36 i don't know how easy they are to access though Oct 20 17:45:05 phh how much off in timing are we talking? usecs, msecs? Oct 20 17:45:57 if there is nothing i don't understand, i'd say perhaps 0.1 ms Oct 20 17:45:59 with RT priority* Oct 20 17:46:39 well im working on an automation controller Oct 20 17:46:52 turning relays on an off, reading sensors etc Oct 20 17:47:07 i dont plan on bit banging any peripherals Oct 20 17:47:19 if you have hardware I2C/SPI, it's fine then Oct 20 17:47:35 plus i could always get an arduino to do time senstive io Oct 20 17:48:01 (**hint** get a stm32 dev board) Oct 20 17:48:11 (afaik, costs less and is more powerful) Oct 20 17:48:20 can it run linux? Oct 20 17:48:30 no Oct 20 17:48:32 and more importantly are there tools for os x Oct 20 17:48:38 wow, no clue Oct 20 17:59:52 well in a couple weeks ill order one i guess Oct 20 18:18:26 <_av500_> damn heating was stuck on error 4F Oct 20 18:18:54 F as in degrees fahrenheit? Oct 20 18:19:01 that would certainly be an error Oct 20 18:19:49 <_av500_> no Oct 20 18:20:05 its his fourth based heating system Oct 20 18:20:12 <_av500_> an error code, according to the fine manual it means overtemperature in some sensor Oct 20 18:20:13 *wild guess* Oct 20 18:20:30 woglinde: that's what we do best Oct 20 18:20:32 dinner first now Oct 20 18:20:36 mru yes Oct 20 18:22:26 <_av500_> i fixed it IT crowd style Oct 20 18:23:48 <_av500_> looks like I need a webcam in the boiler room Oct 20 18:26:32 or train the kids to go check on it once in a while Oct 20 18:27:15 now _I_ heat my place with computers Oct 20 18:27:40 why spend money on plain heat when you can have it do useful work for you as well? Oct 20 18:36:45 exactly! Oct 20 18:37:13 still need to figure out a way to hook them up to the hot water Oct 20 18:37:54 and yes, my flat has electric heating Oct 20 18:38:11 so it really doesn't matter if that electricity does something useful before turning into heat Oct 20 18:40:04 mru: get some 19" racks, build a seasonal data-center Oct 20 18:40:25 I do run more stuff in the winter Oct 20 18:40:46 didn't you see the pic of my "data centre"? Oct 20 18:41:01 ah, that thing on g+ Oct 20 18:41:07 yeah Oct 20 18:41:23 well, that's the "off-site" one Oct 20 18:41:32 (it's in a corner of the bedroom) Oct 20 18:42:01 there are a number of computers and dev boards around my desk as well Oct 20 18:53:57 <_av500_> mru: kids were away as well Oct 20 18:56:13 <_av500_> next time i will leave one on guard duty Oct 20 19:17:41 Hey guys... does anyone know of a mini lcd monitor that can be used with the BeagleBoard xM? Oct 20 19:21:45 you've got 3.14 bazillion options. just pick one. Oct 20 19:23:28 :-) I was actually thinking something like this: http://tincantools.com/product.php?productid=16165&cat=0&page=1&featured Oct 20 19:25:42 Geminizer: that's one option. there are also small hdmi and composite screens. Oct 20 19:26:30 The smallest one I could spot that had hdmi was this -- http://www.amazon.com/Lilliput-Um-70-Monitor-non-touch-Screen/dp/B000AYHY7I Oct 20 19:27:19 I'm sure I'm looking in the wrong place... what I ideally would like is an low profile hdmi display (10 inches or less) Oct 20 19:27:24 that's not even hdmi Oct 20 19:27:33 it's displaylink over usb Oct 20 19:27:49 Geminizer: lilliput do a 5" monitor with hdmi Oct 20 19:27:59 http://www.lilliput.com/p/10/569GL-50NP Oct 20 19:29:13 mru: thanks for the link -- do you think there is an even thinner one out there? Oct 20 19:29:31 no idea Oct 20 19:29:43 I just remembered seeing that one on their website before Oct 20 19:29:58 I have a 7" of theirs and it works fine with beagles and the like Oct 20 19:30:09 Nice Oct 20 19:30:58 I ran into a 7" lvds screen and an lvds/hdmi board once. it was attached over hdmi to a pandaboard. don't ask me why... Oct 20 19:34:41 I think I found what I was looking for -- http://beagleboardtoys.com/wiki/index.php?title=ULCD7_Lite Oct 20 19:38:19 yup buy that one, keep koen and the others employed :) Oct 20 19:39:07 <_av500_> you can connect an old nokia LCD over spi Oct 20 19:39:33 :D Oct 20 19:39:43 <_av500_> and enjoy both colorsa Oct 20 19:39:45 <_av500_> -a Oct 20 19:40:13 or an siemens s35 display and enjoy all 4 colours Oct 20 19:40:52 <_av500_> yep Oct 20 19:41:13 <_av500_> or you do it vetrex style Oct 20 19:41:19 <_av500_> vectrex Oct 20 19:41:28 <_av500_> with an old B&W tv Oct 20 19:41:44 dm8tbr: 4 colours? I only know of 3... Oct 20 19:42:05 mru: rgb+off :) Oct 20 19:42:29 and they didn't mix somehow, pixels only had 4 states Oct 20 19:45:59 ah it was the S25 and it was hideous Oct 20 19:48:09 http://image.ffmobile.com/product/photo/41/93/10046349.113d752def889f98bcecc5eff44b3987.jpg Oct 20 20:01:02 vectrex was vector !raster **** ENDING LOGGING AT Sun Oct 21 02:59:58 2012
