| 00:01.02 | RobotGuy | Same here. :) |
| 00:05.41 | RobotGuy | Hmmmm, I'm looking for a KDE terminal program. |

| 00:07.03 | Sienna | ok, switched to yet another serial port, and I am back to garbage... which is better then nothing, but still |
| 00:07.44 | RobotGuy | Garbage usually indicates a baud rate problem. |
| 00:09.11 | RobotGuy | OK, here is something to try.. Have you got OpenOCD installed with the FTDI libraries? |
| 00:09.14 | Sienna | yeah, but setserial and stty both say 115200 |
| 00:09.37 | Sienna | i think i have the FTDI stuff, as it puts up /dev/ttyUSB0 & 1 |
| 00:10.11 | RobotGuy | OK, get your flyswaatter connected to USB and the Hammer |
| 00:10.12 | Sienna | haven't done any openocd yet |
| 00:10.27 | Sienna | through both JTAG and Serial? |
| 00:10.43 | RobotGuy | You will need OpenOCD. Be sure to use the version from the Hammer Wiki. |
| 00:11.03 | RobotGuy | PC USB --> Flyswattter --> JTAG on the Hammer module. |
| 00:11.39 | RobotGuy | Red side of the JTAG cable goes towrds the edge of the carrier board. |
| 00:12.19 | Sienna | ok, downloaded openocd... |
| 00:12.29 | Sienna | hold on. now have to install... |
| 00:14.11 | Sienna | does the version of libftdi matter? |
| 00:15.03 | Sienna | !!! Who created a tar file that doesn't expand into a subdir! *kicks FTDI* |
| 00:15.57 | RobotGuy | Sienna: Yeah, I hate that sort of thing too, which is why I always test the file before I actually unpack it. |
| 00:16.23 | RobotGuy | Sienna: I would use the version from the Wiki. Which distro are you running? |
| 00:16.29 | Sienna | centos 5 |
| 00:16.40 | RobotGuy | I just switched to Gentoo. :) |
| 00:17.08 | Sienna | i don't have that much patience anymore with linux |
| 00:18.14 | RobotGuy | Gentoo definitely takes more work to get setup, and I still have no sound. |
| 00:18.38 | Sienna | sound doesn't matter for me in linux... it doesn't have itunes anyway |
| 00:18.54 | RobotGuy | Sound is good for indications of actions, etc. |
| 00:19.24 | RobotGuy | I hate having to switch to Windows just to watch YouTube and other videos with sound. |
| 00:20.42 | SpeedEvil | Umm - why"? |
| 00:20.55 | RobotGuy | I am more at home in Linux. |
| 00:21.02 | SpeedEvil | I mean - why switch |
| 00:21.11 | RobotGuy | To Gentoo you mean? |
| 00:21.17 | SpeedEvil | No - to windows |
| 00:21.25 | SpeedEvil | Why isn't sound working |
| 00:21.39 | RobotGuy | Because I don't have sound in Linux right now. I just haven't taken time to check that out yet. |

| 00:27.22 | RobotGuy | OK |
| 00:27.28 | RobotGuy | I had to install minicom. I am still getting Gentoo setup for what I need. |
| 00:27.57 | Sienna | ok, building openocd now i hope |
| 00:28.01 | RobotGuy | Centos 5 may already have the FTDI libraries. |
| 00:28.10 | RobotGuy | From the source on the Wiki? |
| 00:28.32 | Sienna | yeah |
| 00:28.57 | RobotGuy | You have to be sure to enable the libftdi I think. |
| 00:29.39 | RobotGuy | I think there are a couple files you have to copy from the libftdi sources (.h) to OpenOCD also. |
| 00:30.00 | Sienna | apparently |
| 00:30.05 | Sienna | make doesnt make |
| 00:30.18 | RobotGuy | OK, hang on. I need to install OpenOCD here also. |
| 00:35.20 | RobotGuy | I think "--enable-ft2232-libftdi" is what you need to build OpenOCD. |
| 00:35.26 | Sienna | /usr/bin/ld: skipping incompatible /usr/local/lib/libftd2xx.so when searching for -lftd2xx |
| 00:35.29 | Sienna | yay.... |
| 00:35.54 | Sienna | the wiki has the d2xx stuff, not the ftdi open source stuff |
| 00:36.13 | Sienna | ./configure --enable-ft2232-ftd2xx is what i used |
| 00:37.15 | Sienna | and i copied ftd2xx.h and WinTypes.h into /usr/local/include |
| 00:37.28 | Sienna | which let it compile.... but when it got to linking, it gave the error above |
| 00:41.28 | Sienna | now trying with the open source version |
| 00:41.45 | Sienna | which seems to work |
| 00:41.52 | Sienna | ok, i should have openocd now |
| 00:42.27 | RobotGuy | The latest OpenOCD won't work with the stock config files for hammer. |
| 00:42.36 | RobotGuy | Some commands have changed |
| 00:42.47 | Sienna | correction... |
| 00:42.53 | Sienna | openocd: error while loading shared libraries: libftdi.so.1: cannot open shared object file: No such file or directory |
| 00:42.57 | Sienna | :desk |

| 00:47.48 | RobotGuy | I don't know. I am having troubles getting OpenOCD set up. |
| 00:55.55 | RobotGuy | OK, got mine to build. :) |
| 00:56.03 | RobotGuy | Hang on. |
| 00:56.09 | Sienna | oh, mine is built, it just wont let me use it :P |

| 01:01.05 | MonMotha | possibly a permissions issue? |
| 01:01.58 | Sienna | searches seem to indicate that you need to be root to play with the usbfs, but I am |
| 01:04.39 | MonMotha | you don't have to be root, but you do need the appropriate permissions set |
| 01:04.47 | MonMotha | though being root also suffices |
| 01:05.08 | Sienna | unless you run SELinux :P |
| 01:05.22 | MonMotha | true |
| 01:05.26 | Sienna | but anyway, yah, i am getting nowehere with this hammer board under linux |
| 01:05.41 | RobotGuy | Sienna: OpenOCD likes you to be root. |
| 01:05.41 | MonMotha | which doesn't really have much place on a development system in most cases as it just tends to get in the way |
| 01:06.01 | Sienna | oh lord yes does SE get in the way |
| 01:06.04 | MonMotha | openocd by no means likes you to be root. openocd likes to have libusb access to your JTAG thingie |
| 01:06.04 | RobotGuy | I donh't like that OpenOCD has to be run as root either. |
| 01:06.13 | MonMotha | I don't run OpenOCD as root. Works fine. |
| 01:06.21 | RobotGuy | Hmmm |
| 01:06.41 | RobotGuy | Oh, I forgot about libusb! Dang! |
| 01:06.42 | Sienna | any progress over there RobotGuy ? |
| 01:06.49 | Sienna | im stuck |
| 01:07.56 | RobotGuy | Sienna: I am stuck also. :( I don't have a working hammer though, so my results aren't dependable. |
| 01:08.02 | Sienna | got any suggestions MonMotha ? |
| 01:08.11 | MonMotha | not really, no |
| 01:08.25 | MonMotha | errors like this are usually permissions issues |
| 01:08.35 | MonMotha | but if you are running openocd as root, then that is not likely the issue |

| 01:15.40 | RobotGuy | I had all this working under Kubuntu. |
| 01:22.25 | Sienna | ah! I think i may have something |
| 01:22.45 | RobotGuy | I am pretty sure we need --enable-ft2232_libftdi for OpenOCD. |
| 01:22.46 | Sienna | or not... |
| 01:23.22 | Sienna | well, adding "-m32" to the CFLAGS line in the openocd makefile allows me to run openocd at least |
| 01:23.33 | Sienna | however, libftdi still aint finding anything |
| 01:25.13 | RobotGuy | I know, same here. |
| 01:25.26 | Sienna | take it you are running 64bit otoo? |
| 01:25.31 | RobotGuy | There is something I am missing, but I can't see it. |

| 01:32.17 | Sienna | and when you do lsusb -vv you even see it labeled as a flyswatter! (they must have an eeprom on there...) |
| 01:33.12 | RobotGuy | Are you doing "openocd -f hammer.cfg" |

| 01:33.35 | RobotGuy | Try that. It's the correct command. |
| 01:33.39 | Sienna | how will openocd open anything if the FTDI driver doesn't see the flyswatter? |
| 01:34.04 | RobotGuy | If it shows up as Flyswatter, it has to be seen by the driver. |

| 01:39.43 | RobotGuy | That's from /proc/bus/usb/devices |
| 01:39.53 | RobotGuy | The URL I put above. |
| 01:40.10 | Sienna | and you show a flyswatter too... is that your point? |
| 01:40.23 | RobotGuy | It shows the driver finds it. |
| 01:40.30 | RobotGuy | ftdi_sio |
| 01:40.45 | Sienna | are you supposed to use that driver with libftdi? |
| 01:40.56 | RobotGuy | I still can't seem to get openocd to find it though. |
| 01:40.56 | Sienna | libftd2xx said remove it |
| 01:41.23 | RobotGuy | Hmmmm, that could be my problem. Wrong driver catching then Flyswatter. |
| 01:44.05 | RobotGuy | ftdi_sio is the kernel driver, I think. |
| 01:44.11 | Sienna | it is |
| 01:44.22 | Sienna | and it relies on usbserial |
| 01:44.41 | RobotGuy | I need that for other things though, or at least I think I do. |
| 01:44.44 | Sienna | i just loaded both, and my FTDI library still sees squate |
| 01:44.53 | RobotGuy | It finds my USB-UIRT IR dongle. |
| 01:45.16 | RobotGuy | I'll have to rebuild my kernel to remove that driver. |
| 01:45.32 | Sienna | ah yes, from the libftdi page: |
| 01:45.33 | Sienna | Note: When you get a -5 error "can't claim usb device" during ftdi_usb_open(), make sure the kernel ftdi_sio driver is unloaded. |
| 01:46.36 | Sienna | i am going to send an email to the ftdi driver people... see if they have any insight |
| 01:47.15 | RobotGuy | I bet prpplague will have an answer tomorrow when he's here. |
| 01:50.12 | RobotGuy | Sienna: http://www.pastebin.ca/1031639 <-- this is what I get when I run openocd. |

| 15:14.44 | T0mW | prpplague: the spi system is using the HARDWARE spi controller, not a bitbanger. I'm running the enc28j60 at full speed. |
| 15:15.08 | prpplague | T0mW: cool, done any thruput tests? |
| 15:15.55 | T0mW | prpplague: no, there is an issue with packet loss. Using "ping -s 800 -c 50 x.x.x.x" I am seeing 4%..12% packet loss. |
| 15:16.03 | T0mW | not sure why at this point. |
| 15:16.25 | prpplague | T0mW: what clock rate are you using for the spi controller? |
| 15:16.38 | T0mW | prpplague: but, if you have a known good board, you can test the code and see if I have a hardware issue (rbias?). |
| 15:16.55 | T0mW | prpplague: 0x5900000c == 0 |
| 15:17.00 | prpplague | T0mW: yea, i'll me testing with two known good boards |
| 15:17.19 | prpplague | T0mW: hmm, i'll have to check that value |
| 15:17.24 | prpplague | T0mW: but i think thats too high |
| 15:17.39 | T0mW | prpplague: hdparm -t reports 311 KB/s xfer rate on the MMC card |
| 15:17.39 | prpplague | T0mW: seems like that would be about 22mhz |
| 15:18.24 | T0mW | prpplague: I've read the data sheet and it calls for a 25MHz max spi clock rate. And, I have a B5 rev chip... |
| 15:18.51 | prpplague | T0mW: hmm, i thought the optimal was for something around 12mhz |
| 15:18.52 | T0mW | prpplague: I could try it at 1MHZ an see. but, I will patch you. |
| 15:19.05 | T0mW | prpplague: I tried 8MHz too |
| 15:19.06 | prpplague | T0mW: okie dokie thanks |

| 15:22.40 | prpplague | T0mW: np |
| 15:24.41 | T0mW | prpplague: is there anybody actively working on the spi system? other than Mr. Dooks? |
| 15:25.01 | prpplague | T0mW: there are a few, there is a mailing list |
| 15:25.04 | prpplague | T0mW: but to be honest |
| 15:25.28 | prpplague | T0mW: the structure is so hard to start off with, that people usually try it for a little while and then give up |
| 15:25.35 | prpplague | T0mW: and just write a direct access driver |
| 15:26.16 | T0mW | prpplague: the issue with the somewhat useless s3c2410_spi_info struct is going to be a big one. |
| 15:26.33 | prpplague | indeed |
| 15:26.53 | T0mW | prpplague: you know about the pin_cs needing to be an array, correct? |
| 15:27.26 | prpplague | T0mW: i recal something about that, but i've not looked in awhile |
| 15:27.40 | T0mW | the platform_data struct gets "lost" in differing parts of the spi system (is set to NULL). |
| 15:28.31 | T0mW | for example, during the enc28j60_probe, the spi struct has chip select info. But, during the net_open, it is empty. |
| 15:29.40 | T0mW | so, you cannot rely upon using a common spi chip select function for your bus such as "s3c2410_gpio_setpin(spi[cs].pin_cs, pol);" |
| 15:29.57 | T0mW | doh |
| 15:30.17 | T0mW | so, you cannot rely upon using a common spi chip select function for your bus such as "s3c2410_gpio_setpin(spi.pin_cs[cs], pol);" |
| 15:30.17 | T0mW | heh |
| 15:44.03 | prpplague | ok now explain this, on american airlines, i can go from dfw to moscow for 1/2 of what it costs to from dfw to lax |
| 15:44.54 | chouimat|work | prpplague: special pricing for internation flight :) |
| 15:45.00 | chouimat|work | +al |
| 15:45.32 | prpplague | chouimat|work: no its just AA they have screwy pricing |
| 15:46.20 | chouimat|work | prpplague: ottawa - quebec city round trip == 430$ I can have a flight to Paris for about the same price |
| 15:47.01 | prpplague | chouimat|work: but like for instance for barbados, they generally don't want american tourists, so they tax flights from the US very heavily, and then use the tax money towards subsidized flights from canada and the UK |
| 15:47.37 | chouimat|work | prpplague: this is a great idea ... maybe we should do this here too :) |

| 19:23.21 | prpplague | Sienna: do a: man setserial |
| 19:23.38 | CosmicPenguin | sjhill: hey homey |
| 19:23.38 | prpplague | Sienna: hehe linux not to blame, vendors not releasing full specs |
| 19:24.20 | Sienna | i was looking at setserial last night, and it made no sense what needed to be changed. I guess thats yet another thing to figure out later |
| 19:25.05 | Sienna | do you have anything on SPI yet w/ regards to the Hammer? |
| 19:25.21 | Sienna | i saw I2C somewhere when I was poking around, but didn't see SPI |
| 19:27.05 | prpplague | Sienna: yea spi and i2c are both supported fully on the hammer/s3c2410 |
| 19:27.31 | Sienna | so how do 'high level' user space programs get to them? |
| 19:27.36 | prpplague | Sienna: one aspect that i;ve been trying to get across to robotguy is there are several methods of i2c and spi support |
| 19:28.19 | prpplague | Sienna: there are user space device nodes that you can use, however that isn't nessarily the best option |
| 19:28.40 | prpplague | Sienna: it mainly depends on what kind of device it is and what you want to do with it |
| 19:28.44 | Sienna | Oh, is Rusty around there at all? I am revising the RDP design of mine, and wondered if he had a preference for a 2x27 or 3x18 stacking connector |
| 19:29.03 | prpplague | Sienna: hehe, rusty rarely shows up at the office, hehe |
| 19:29.05 | Sienna | (personally am leaning to the 3x18) |
| 19:29.16 | Sienna | oh, works from home? Nice! |
| 19:29.21 | prpplague | hasn't actually seen rusty in over a month |
| 19:29.33 | prpplague | Sienna: drop him an email |
| 19:29.39 | Sienna | or is he always on business travel |
| 19:29.55 | Sienna | ok |
| 19:30.04 | prpplague | Sienna: hehe, rusty is retired from AML and does tincantools as a hobby |
| 19:30.36 | Sienna | so, for I2C, the most common is sonar. They are relatively slow, only generating new data maybe ten times a second if you abuse them |
| 19:31.02 | prpplague | Sienna: do you have a typical part? |
| 19:31.18 | Sienna | For SPI, I have a tri-axis accel here that I want to start playing with that will generate new data on the order of 2khz or something IIRC |
| 19:31.47 | Sienna | Sure: Daventech SRF-08 |
| 19:31.59 | prpplague | googles |
| 19:32.19 | Sienna | Dale has my datasheet, or I would look up whatever |
| 19:33.19 | Sienna | (about time yum finished.... now i can try looking again for those packages on the buildroot page) |
| 19:33.50 | *** join/#edev drath_ (i=vmaster@p5B07E620.dip.t-dialin.net) |
| 19:34.43 | prpplague | Sienna: ok so, for the DRF-08, a kernel module with be the best choice |
| 19:35.06 | prpplague | Sienna: you'd want the vast majority of the functionality hidden and just provide data |
| 19:35.07 | Sienna | thats what i figured... most of this would need low level things |
| 19:35.32 | prpplague | Sienna: doing a module for this would be relatively painless |
| 19:35.39 | Sienna | i ordered a book from amazon today on writing device drivers... it should have info on turning them into modules |
| 19:35.44 | prpplague | Sienna: i'd be surprised if there wasn't one already |
| 19:35.50 | Sienna | oh |
| 19:35.53 | Sienna | that would be nice |
| 19:36.01 | Sienna | cause I am really not a low level gal |
| 19:36.36 | Sienna | what is the difference between zlib and zlib1g? |
| 19:38.04 | prpplague | Sienna: good question, don't have an answer |
| 19:38.15 | prpplague | Sienna: looking at the srf-08 protocol now |
| 19:38.22 | Sienna | do you think i need it for buildroot? |
| 19:39.51 | prpplague | Sienna: usually anything buildroot needs it downloads |
| 19:40.01 | Sienna | ok, will try then! |
| 19:40.12 | prpplague | Sienna: there are some basic tools that it needs, but usually it will let you know |
| 19:40.37 | prpplague | Sienna: where did you order your srf-08 from? |
| 19:41.04 | Sienna | you can get them from many places... Junun.org, Acroname, prolly TrossenRobotics |
| 19:42.00 | Sienna | You prolly don't want to volunteer to make modules for everything... there are a lot of components we use :P |
| 19:42.40 | Sienna | however, one thing we will need is a module for the ADS7844 that will be on the RDP... *wink wink* :P |

| 19:43.08 | Sienna | hello like2wise |
| 19:44.07 | prpplague | Sienna: the real question is how detailed do you want the support |
| 19:44.31 | prpplague | Sienna: did you check to see if the ads7844 is already supported? |
| 19:44.39 | Sienna | i am not an embedded developer except by neccesecity. |
| 19:44.55 | Sienna | honestly, i don't even know how to do that. pointers? |
| 19:45.50 | Sienna | (neccessity meaning I have to learn this all from scratch) |
| 19:45.54 | prpplague | Sienna: http://www.google.com/linux |
| 19:46.37 | prpplague | Sienna: what is the ads7844? |
| 19:47.03 | Sienna | should be a 8 channel 12 bit ADC made by TI |
| 19:47.08 | Sienna | it uses SPI |
| 19:47.21 | Sienna | let me check the schematic, make sure i got the part right |
| 19:47.46 | Sienna | yep |
| 19:48.33 | prpplague | ahh one sec |
| 19:48.35 | Sienna | pokes Firefox... where did my find dialog go? |
| 19:48.36 | prpplague | looks |
| 19:50.23 | like2wise | hi Sienna, all |
| 19:50.35 | Sienna | great... now i hid my FF menu bar and I can't get it back |
| 19:50.58 | *** join/#edev ico2 (n=ico2@modem-95.cougar.dialup.pol.co.uk) |
| 19:51.53 | prpplague | Sienna: the ADS7843 is a touch screen version of the ADS7844, basically identical protocol from what i'm seeing |
| 19:52.27 | agaffney | Sienna: owned |
| 19:52.38 | Sienna | owned? I am sorry? |
| 19:52.48 | agaffney | nm :P |
| 19:53.02 | prpplague | Sienna: the ADS7843 has a linux driver for the 2.6 kernel |
| 19:53.18 | prpplague | Sienna: you could probably start with that and do just a few tweaks |
| 19:53.24 | Sienna | can you people with working firefoxs please look up the key to get my menu bar back? |
| 19:53.43 | Sienna | (and looking at the 7843) |
| 19:54.05 | prpplague | Sienna: F11 |
| 19:54.07 | prpplague | Sienna: iirc |
| 19:54.35 | Sienna | why can't i click a link you stupid program! and they keep thinking linux is ready for the desktop... |
| 19:55.01 | Sienna | thanks for trying prpplague, not it |
| 19:55.05 | prpplague | Sienna: what distro are you using? |
| 19:55.08 | Sienna | centos |
| 19:55.15 | prpplague | Sienna: interesting |
| 19:55.29 | prpplague | Sienna: yea the ADS7843 uses the same protocol |
| 19:55.36 | prpplague | Sienna: as the ADS7844 |
| 19:55.41 | Sienna | ok, that would reduce the work |
| 19:56.01 | Sienna | so then would just have to modify things slightly to get more 'results'? |
| 19:56.09 | prpplague | Sienna: its also the same as the ads7845 |
| 19:56.14 | prpplague | Sienna: should |
| 19:56.29 | prpplague | Sienna: the real question is do you want to use the spi and i2c subsystems |
| 19:56.38 | Sienna | ? |
| 19:56.42 | prpplague | Sienna: and just write small and quick kernel modules |
| 19:57.15 | Sienna | kernel modules populate the /proc fs don't they? |
| 19:57.15 | prpplague | Sienna: the subsystems provide a framework for you to write very generic i2c and spi drivers |
| 19:57.54 | prpplague | Sienna: they can, but procfs usage is generally considered bad form these days ( i much prefer procfs) |
| 19:58.05 | Sienna | oh.. what replaced it? |
| 19:58.10 | prpplague | sysfs |
| 19:58.18 | Sienna | ok |
| 19:58.29 | agaffney | Sienna: you're a bit behind :) |
| 19:58.32 | prpplague | much more robust, but(imho) much more difficult for small applications to use |
| 19:58.37 | Sienna | markes yet another topic to learn about |
| 19:58.38 | agaffney | sysfs has been the new hotness for quite some time |
| 19:58.51 | Sienna | agaffney, I haven't done code since college... |
| 19:58.55 | Sienna | well, i have, but it was php |
| 19:59.03 | agaffney | that doesn't count ;) |
| 19:59.10 | agaffney | I say that as a php coder |
| 19:59.38 | agaffney | as well as a C, perl, python, bash, qbasic, and VB coder :P |
| 19:59.40 | prpplague | Sienna: well, what we want to find out, is what devices you guys are looking to use, and the best methods of allowing non-kernel devrs to access the data |
| 19:59.42 | Sienna | i am not a embedder girl! I Love mechanics. All this stuff makes my head spin :P |
| 20:00.13 | Sienna | s/embedder/emdedded |
| 20:01.07 | Sienna | if there is any way to turn these devices into 'pipes', that might be useful. Every language under the sun knows how to read and write a file descriptor |
| 20:01.37 | prpplague | Sienna: correct, what would be the best solution would to have to a device node under /dev |
| 20:01.39 | Sienna | so, if we can make something in /proc or /sys that we can read for a result or write a command too, i think that might be ideal |
| 20:01.56 | prpplague | Sienna: for example, /dev/srf0 |
| 20:02.07 | Sienna | i don't know about /dev usage either |
| 20:02.14 | prpplague | Sienna: ahh |
| 20:02.37 | prpplague | Sienna: ok, so i can do a quick and dirty srf08 module that uses procfs |
| 20:02.41 | Sienna | maybe a brief explanation? What is the difference (high level) between /proc /dev and /sys>? |
| 20:03.05 | prpplague | Sienna: procfs and sysfs both are for "human" readable functionality |
| 20:03.42 | chouimat|work | <PROTECTED> |
| 20:03.43 | prpplague | Sienna: for example to turn on a led using the sysfs led entries you could do: echo 1 > brightness |
| 20:03.53 | agaffney | Sienna: high level? not much |
| 20:03.59 | Sienna | yes, i saw that example on the wiki |
| 20:04.16 | Sienna | (i was amused for five minutes turning leds on and off.... :look) |
| 20:04.19 | agaffney | but you could do the same thing with a procfs entry |
| 20:04.26 | agaffney | and if you *really* wanted, a /dev entry |
| 20:04.32 | agaffney | but that would be a bit unusual |
| 20:04.37 | prpplague | Sienna: device nodes provide a much more robust connection between an application and kernel spac |
| 20:04.50 | chouimat|work | agaffney: cat /dev/urandom > /dev/dsp :) |
| 20:04.55 | prpplague | Sienna: you can use ioctl's to configure and control the device |
| 20:05.09 | agaffney | chouimat|work: another hit pop song! |
| 20:05.15 | chouimat|work | hehe |
| 20:05.18 | prpplague | Sienna: as well as receive pre-formated data to and from the device node |
| 20:05.21 | agaffney | s/pop/rap/ where appropriate |
| 20:05.36 | Sienna | adds ioctl to the list |
| 20:05.38 | prpplague | Sienna: for example the ttyUSB1 you are using is an example of character based device node |
| 20:05.57 | Sienna | *nods* |
| 20:06.11 | prpplague | Sienna: again the real question is, how you expect to communicate with the devices like the srf-08 |

| 20:07.43 | agaffney | people still use fax? |
| 20:07.57 | Sienna | honestly prpplague, as long as I can get values into a variable at 10Hz or so for sonar, and at KHz for acceleration and gyration, i don't care if its a hack to get them there LO |

| 20:11.45 | Sienna | 2) SRF-08 (which should use the same comms protocol as the SRF-10 IIRC, but i can check) |
| 20:12.28 | Sienna | 3) the SPI three axis accelerometer I am using, and then the spi gyros. |
| 20:12.54 | Sienna | again, my suggestions, take them with as much salt as you can swallow ;P |

| 20:15.59 | agaffney | if this guy sucks so bad, why is he still there? |
| 20:16.42 | prpplague | agaffney: because managment just doesn't give a rats ass |
| 20:16.43 | ohsix | perhaps he plys his skills at sucking to a superiors member |
| 20:16.54 | prpplague | ohsix: indeed |

| 20:17.50 | prpplague | he's very very good at blamming everyone else |

| 20:19.21 | prpplague | Sienna: probably have a .mozilla dir with settings |
| 20:19.31 | agaffney | then start firefox |
| 20:20.03 | Sienna | i rm -rf that directory... still did it |
| 20:22.45 | agaffney | that's...unlikely :P |

| 20:31.31 | markus | i use ubuntu. |
| 20:31.39 | Sienna | you can get gcc for it though, right? (*wonders what agaffney can't do with ubuntu*) |
| 20:32.28 | Sienna | if I am trying to get gentoo... which architecture do i choose. I don't see x86_64 |
| 20:32.46 | agaffney | Sienna: amd64 |
| 20:33.04 | agaffney | it was named before x86_64 was anything other than amd64 :P |

| 20:36.49 | Sienna | was that sarcastic? (i know at times I have been a b***h this week... sorry all!) |
| 20:37.15 | prpplague | Sienna: no, not at all |
| 20:37.40 | prpplague | Sienna: just that i've been using linux desktop since july of 1997 |

| 20:39.41 | prpplague | googles |
| 20:39.44 | Sienna | a 3D CAD package |
| 20:39.48 | prpplague | ahh |
| 20:40.23 | Sienna | the free single part version is very easy to use |
| 20:40.39 | Sienna | if you ever needed to make a part.... |
| 20:40.55 | prpplague | doesn't do mechanical very well |

| 20:41.48 | Sienna | me, i am a jack of all trades, so i suck equally at everything |
| 20:42.00 | Sienna | thats another popular package, yes |
| 20:42.18 | Sienna | all of them are so much money though... they need 'hobby' licensing |
| 20:42.35 | prpplague | hehe indeed |
| 20:42.48 | prpplague | welp, suspend resume working |
| 20:43.01 | Sienna | later prpplague |

| 20:44.12 | prpplague | Sienna: hehe |
| 20:44.34 | prpplague | Sienna: no i was saying that i now have suspend/resume working on my development platform |
