| 02:11.26 | prplague | hey |
| 02:12.01 | g1powermac_APW | did ya see the higher quality photos I got of the zipit? |
| 02:12.08 | prpplague | yea |
| 02:12.13 | g1powermac_APW | I also got a shot with all chips marked |
| 02:12.17 | g1powermac_APW | k |
| 02:12.37 | g1powermac_APW | this is new though: http://www.flickr.com/photos/77471288@N00/2443844509/ |
| 02:12.45 | g1powermac_APW | I resurrected my dev system :-) |
| 02:12.56 | prpplague | looks |
| 02:13.07 | g1powermac_APW | now with dual monitors |
| 02:13.13 | prpplague | nice looking work area |
| 02:13.35 | g1powermac_APW | yea, nice and clean from just setting it up |
| 02:13.51 | g1powermac_APW | oh yea, the computer is built in an ammocan :-) |
| 02:14.39 | g1powermac_APW | you can see how it was constructed here: http://www.flickr.com/photos/77471288@N00/page3/ |
| 02:15.37 | g1powermac_APW | actually, you've prolly seen it when I was originally building the thing, though maybe not |
| 02:15.46 | g1powermac_APW | it was over 2 years ago |
| 02:19.05 | g1powermac_APW | well, tomorrow I think I'll work on the linux side of this machine, got the windows part completely updated and such tonight |
| 02:19.39 | g1powermac_APW | could be interesting getting linux to do the dual monitor thing, I know it was giving me grief about the video card I got to begin with only one monitor |
| 02:20.29 | g1powermac_APW | oh yea, just remembered, I got a question for you |
| 02:21.17 | g1powermac_APW | prpplague: I was looking at the datasheet for the pxa270 earlier and if I read the datasheet right, wouldn't the jtag pins be on the left side of the chip toward the middle vertically? |
| 02:22.41 | g1powermac_APW | reason i ask is because there is four test point markings right near what I thing would be the jtag pins: http://www.flickr.com/photos/77471288@N00/2441468389/sizes/l/in/photostream/ |
| 02:24.04 | g1powermac_APW | I figure the actual TP's are under the shield for the wifi chip |
| 02:26.40 | g1powermac_APW | brb, switching to other computer |
| 02:28.08 | g1powermac_PB | ok, back |
| 02:29.30 | RobotGuy | Oh, here I am. I forgot I had X-Chat running. |
| 02:29.45 | g1powermac_PB | RobotGuy: :-) |
| 02:30.23 | RobotGuy | I'm still looking for those DIP level translator chips. I know DigiKey has them but I have misplaced my notes and want to order some in a week. |
| 02:30.43 | RobotGuy | Hi g1powermac_PB |
| 02:30.47 | g1powermac_PB | what kind of level shifting chips? rs232? |
| 02:36.31 | prpplague | g1powermac_PB gotta make sure you have the correct bga package, there are two |
| 02:36.42 | g1powermac_PB | oh |
| 02:36.50 | prpplague | g1powermac_PB from what i saw looking from the top, the jtag is on row R |
| 02:37.00 | prpplague | thats for the pbga package |
| 02:37.06 | g1powermac_PB | ahh, ok |
| 02:50.17 | *** join/#edev slapin_nb (n=slapin@saris-243.ip.PeterStar.net) |
| 02:50.37 | g1powermac_PB | interesting, so in this case, the jtag pins would be toward the top edge of the chip and bit toward the right corner |
| 02:50.59 | g1powermac_PB | kinda right where one of the yellow wires attach |
| 02:59.45 | prpplague | should be row R |
| 02:59.58 | prpplague | its near those resistors on the right side |
| 03:01.21 | g1powermac_PB | well, if you look at the markings on the board, the letter 'rows' are the vertical ones |
| 03:01.35 | g1powermac_PB | the number rows are horizontal |
| 03:02.13 | g1powermac_PB | so it can't be on the right side if those markings are correct |

| 03:07.49 | prpplague | pulls up the datasheet |
| 03:08.44 | prpplague | ahh i was looking at the oreintation wrong |
| 03:10.55 | prpplague | g1powermac_PB yea the correct orientation is as you suggested |
| 03:11.12 | prpplague | g1powermac_PB from the picture its on the top right hand side |
| 03:12.16 | g1powermac_PB | ok, so now the question is, do you still think the jtag is brought out to that mess above the chip? |
| 03:14.37 | RobotGuy | g1powermac_PB: 3.3V to 5V and the reverse, also for I2C and SPI. |
| 03:14.55 | RobotGuy | prpplague: Greetings |

| 18:54.43 | g1powermac_PB | yea, was thinking that |
| 18:55.14 | g1powermac_PB | technically, the debian installer/grub should be able to do it |

| 19:35.27 | solar | GPSFan: I read over what ppl arguments were for them before and attempted to address them. I've not pushed back to the bb-repo yet however. |
| 19:35.45 | solar | was hoping to get some feedback from some ppl that might actually use it. |
| 19:36.07 | solar | http://tinderbox.dev.gentoo.org/portage/local/misc/busybox-devmem.patch if anybody wants to test expected behavior |
| 19:37.35 | GPSFan | solar: I'll take a look at the patch, my opinion probably means squat to the upstream folks, but I'll take a look. |
| 20:04.16 | prpplague | solar there is no reason you have to keep the kernel under 1mb, you can always change the values |

| 20:05.44 | prpplague | solar nice busybox applet |
| 20:05.55 | prpplague | solar gonna submit that for the busybox folks? |
| 20:11.54 | solar | prpplague: my plan was to leave it in gentoo for a release cycle. wait for no bug reports. If vapier sees the applet while bumping to the next version he is likely to commit it. |
| 20:12.36 | prpplague | solar so you already spoke to vapier about it? |
| 20:12.37 | solar | otherwise I need to get landley to update my ssh key on svn |

| 20:14.43 | solar | in that thread Bernhard Fischer lists what he saw as the problems. |
| 20:15.14 | solar | the only thing I did not do was try to mash what used to be the two switch statements |
| 20:15.34 | prpplague | yea looking now, i'll patch up some busybox stuff in the morning and put it out on some of our dev systems that current use devmem |
| 20:15.54 | prpplague | should have some good feedback in less than a week |

| 20:36.24 | solar | yeah thats what mdev finds the serial device as |
| 20:37.02 | prpplague | solar http://www.elinux.org/Hammer_Button_Driver |
| 20:37.31 | prpplague | the i've added small system call to the generic pushbutton driver |
| 20:39.03 | prpplague | solar i don't plan on keeping that functionality, it reall is only helpful to some folks moving up from avrs and pics |
| 20:39.40 | prpplague | plus the kernel maintainers would never accept it |
| 20:39.52 | prpplague | they frown on system calls in the kernel |
| 20:44.40 | solar | replace it with an ioctl? |
| 20:45.32 | prpplague | solar just use the standard events with a daemon to monitor for button presses |
| 20:52.36 | solar | thats normally done via dbus? |
| 20:53.14 | prpplague | yea you can use dbus but for most embedded designs dbus is way too big and bulky |
| 20:53.32 | prpplague | so most poeple will create specific daemons for the application |
| 20:56.38 | RobotGuy | I've applied the patch to 2.6.25 and it seems to compile just fine. I can't test it right now though, but have an image already made. |

| 21:20.51 | MonMotha | prpplague: doubtful |
| 21:21.10 | MonMotha | at least not without optics |
| 21:21.28 | prpplague | MonMotha yea, thats what i was thinking, it'd need to be about 10 times the size |
| 21:23.46 | MonMotha | at least |
| 21:24.01 | MonMotha | as a benchmark, the great wall of china is visible from earth orbit |
| 21:24.10 | MonMotha | without optical assistance |
| 21:29.01 | MonMotha | prpplague: you know much about capacitive touchscreens? |
| 21:32.28 | prpplague | MonMotha only a little we, researched them for our next gen industrial pds |

| 23:15.33 | prpplague | interesting deal with the dilbert.com upgrade |
| 23:16.03 | prpplague | another example of website "upgrades" that cause the site to be unusable |
| 23:16.26 | prpplague | just like the weather.com and star-telegram.com sites |
| 23:16.42 | prpplague | both did upgrades in the last year that make the sites almost completely useless |
| 23:16.45 | MonMotha | prpplague: many websites are already unusable as far as I'm concerned |
| 23:16.51 | MonMotha | doesn't have flash installed |
| 23:17.19 | prpplague | MonMotha that is indeed true, but when they go from a totally functional site to useless in 48 hours |
| 23:17.47 | prpplague | but its also an example how there is a large disconnect from media types |
| 23:17.55 | MonMotha | yes |
| 23:18.06 | MonMotha | regarding my capacitive touchscreen..got any good info? |
| 23:18.13 | prpplague | like the recent purchase of the discovery channel but harpo, oprah's publishing company |
| 23:18.17 | MonMotha | I want to make a rather large one. Like 30" diagonal |
| 23:18.21 | prpplague | MonMotha got some at the office |
| 23:18.38 | prpplague | MonMotha we ended up going with resistive since it was more cost effective |
| 23:18.47 | MonMotha | I noticed Analog Devices has some neat capacitance measurement chips |
| 23:19.10 | MonMotha | but electrostatics was never my thing, so I'm not entirely sure what an optimal design for the conductive surfaces looks like, especially at that scale |
| 23:19.31 | MonMotha | prpplague: I need multiple touch capability |
| 23:19.38 | MonMotha | and it needs to be reasonably durable |
| 23:19.42 | MonMotha | cost is not a major factor |
| 23:21.09 | prpplague | MonMotha SFE has some cap devices iirc |
| 23:21.51 | prpplague | MonMotha as soon as oprah purchased discovery channel back in october she started making major changes |
| 23:21.56 | prpplague | its a real shame |
| 23:21.58 | MonMotha | well, putting together things like simple dials, sliders, etc. based on capacitive sensing is pretty eas |
| 23:21.59 | MonMotha | y |
| 23:22.06 | MonMotha | and yes, witness Smash Lab |
| 23:22.40 | prpplague | http://www.sparkfun.com/commerce/product_info.php?products_id=7918 |
| 23:22.54 | MonMotha | yup |
| 23:23.00 | MonMotha | looks like a breakout for one of the ADI chips |
| 23:23.50 | MonMotha | I could potentially ask an app engineer at ADI. I know a couple, though none in this field |
| 23:41.29 | RobotGuy | I think I am going to put http://www.trossenrobotics.com/store/p/5196-Robotics-Connection-Serializer-WL.aspx on W.A.L.T.E.R. controlled by a Hammer (TTL level serial). |
| 23:42.35 | RobotGuy | That is assuming, for now, that the Luminary Micro Eval board for the LM3S6965 does not work out. |

| 23:46.18 | g1powermac_PB | is pondering if he should get a new soldering iron/station |

| 23:49.08 | g1powermac_PB | heya RobotGuy |
| 23:49.16 | RobotGuy | g1powermac_PB: Greetings |
| 23:49.28 | g1powermac_PB | is looking at new soldering stations |
| 23:49.43 | g1powermac_PB | the one I got isn't super adequate |
| 23:50.02 | g1powermac_PB | need better heat control and smaller tip |
| 23:50.05 | MonMotha | I like my WESD-51 |
| 23:50.18 | MonMotha | best thing I've found short of a Metcal |
| 23:50.33 | RobotGuy | I have the WES51, but wish I had the WESD-51 |
| 23:50.41 | MonMotha | they're pretty much the same |
| 23:50.47 | MonMotha | the D just adds digital control |
| 23:51.01 | RobotGuy | I know |
| 23:51.13 | g1powermac_PB | hmm, those look nice |
| 23:51.16 | MonMotha | both are temp regulated |
| 23:51.20 | MonMotha | which is the big thing to get |
| 23:52.12 | g1powermac_PB | mine has some form of temp control, just a pot with markings 1 through 5 |
| 23:52.18 | prpplague | g1powermac_PB qualify pricy? |
| 23:52.41 | MonMotha | the Wellers do have changeable tips |
| 23:52.45 | g1powermac_PB | prpplague: depends on what it does :-) |
| 23:52.52 | MonMotha | though I've found the stock tip more than adequate for my usage |
| 23:53.00 | RobotGuy | I got my WES51 with solder wick and flux for $108.00 locally. |
| 23:53.10 | MonMotha | about the only thing I sometimes want a smaller tip for is tacking to 0.5mm QFP leads |
| 23:53.23 | MonMotha | and then you want a REALLY small tip :) |
| 23:53.26 | RobotGuy | I have a 0.4mm tip for mine. |
| 23:53.32 | g1powermac_PB | ya |
| 23:53.42 | MonMotha | small tips are not necessary for most work |
| 23:53.51 | g1powermac_PB | I built my minila with the tip that came with my cheapo iron, that was fun |
| 23:54.09 | MonMotha | well, shadio rack irons and tips suck |
| 23:54.13 | prpplague | MonMotha i really prefer a 1/64 for smd stuff like 603's |
| 23:54.30 | MonMotha | I've never had a need for a tiny tip, really |
| 23:54.39 | g1powermac_PB | well, it isn't a ratshack one, i picked this sucker up at Home Depot/Lowes ;-) |
| 23:54.41 | MonMotha | well, 0402s are tough, I guess |

| 23:54.59 | RobotGuy | I have been trying to get my courage up to try soldering some QFPs. |
| 23:55.02 | g1powermac_PB | that kinda looks like mine |
| 23:55.10 | g1powermac_PB | though mine is a weller, I think |
| 23:55.21 | MonMotha | ah, those |
| 23:55.29 | MonMotha | those aren't actually temp controlled |
| 23:55.33 | MonMotha | you just vary the power lvel |
| 23:55.34 | RobotGuy | There are QFPm TSSOP, and SOIC packages I would like to be able to use. |
| 23:55.45 | g1powermac_PB | MonMotha: yup |
| 23:55.47 | RobotGuy | s/QFPm/QFP/ |
| 23:56.28 | MonMotha | the wellers are actually temp controlled |
| 23:56.37 | RobotGuy | It sucks that one apparently needs a different JTAG for AVRs and ARM. |
| 23:56.37 | MonMotha | you dial up the temp you want and it holds that temp as best it can |
| 23:57.11 | g1powermac_PB | yea, would be nice to have one like that |
| 23:57.29 | MonMotha | temp controlled irons are practically required if you have to work on cheap phenolic type boards (FR-2 or similar) |
| 23:57.35 | MonMotha | they delaminate at higher temps really quickly |
| 23:57.47 | MonMotha | but you need some actual power in order to heat things up |
| 23:58.05 | RobotGuy | I need to wire up a 2x10 to 2x7 JTAG cable, but don't have the connectors I thought I had. |
| 23:58.12 | joe_bleau | WTCTP--the techs can't adjust the temp just 'cause they want to go faster! |
| 23:58.33 | MonMotha | my weller actually has a lockout featur |
| 23:58.43 | joe_bleau | Yeah, until the techs find a magnet. |
| 23:58.47 | MonMotha | it's trivially defeatable if you know how it works, though :) |
| 23:58.48 | RobotGuy | I like the auto-shutoff feature. |
| 23:58.48 | MonMotha | exactly |
| 23:59.09 | g1powermac_PB | wonders if he should just splurge and get a hot air rework station |
| 23:59.14 | MonMotha | I do crank the temp up sometimes...to burn enamel of magnet wire |
