| 19:56.46 | prpplague | CosmicPenguin: ping |
| 19:56.50 | CosmicPenguin | pong |
| 19:57.31 | prpplague | CosmicPenguin: hey, quick question, is there a seperate subsystem for handling battery fuel gauges for under linux? |
| 19:57.55 | ds2 | panic()? ;) |
| 19:57.56 | CosmicPenguin | seperate from what? |
| 19:59.01 | prpplague | CosmicPenguin: well seeing how battery fuel gauges don't really fit into a group other than possibly under power management, i wasn't sure if there was specific area |
| 19:59.38 | CosmicPenguin | they kind of live on their own right now |
| 19:59.41 | CosmicPenguin | as platform drivers |
| 19:59.53 | ds2 | actually, isn't there something in the what used to be lmsensor stuff? |
| 19:59.53 | prpplague | CosmicPenguin: thats kinda what i thought |
| 20:02.24 | prpplague | think i'll just add it as a support i2c device |
| 20:03.36 | steliosk | Anyone knows what the cheapest device with a small lcd (grafix), a serial port and the ability to run linux would be ? |
| 20:03.39 | steliosk | Need something in 50-100 pcs quantity for a really low cost project |
| 20:04.46 | prpplague | steliosk: need alot more info, what physical size, what resolution, what type of serial port, what power rating? |
| 20:05.02 | prpplague | steliosk: gotta do a quick meeting, be back in 15minutes |
| 20:07.31 | steliosk | pprpplague : size and resolution are not that important. It will display some numbers and vector data (lines) |
| 20:08.07 | steliosk | pprpplague : Serial port should go up to 115K although i dough it will above 9600 in most cases |
| 20:08.37 | steliosk | pprpplague : power supply battery and/or 12V from car adapter |
| 20:28.03 | prpplague | steliosk: what kind of price range are you looking for? |
| 20:28.45 | steliosk | sub 100$. around 70-75 would be good |
| 20:29.01 | steliosk | less than that great :) |
| 20:29.06 | prpplague | steliosk: including a lcd? |
| 20:29.21 | steliosk | yeah |
| 20:29.42 | prpplague | steliosk: not gonna happen unless you are "repurposing" a device |
| 20:30.22 | steliosk | thinking about that also. anything you recommend ? |
| 20:30.55 | prpplague | steliosk: you can get a zipit for $50 these days |
| 20:31.43 | prpplague | steliosk: needs to run full linux correct? |
| 20:32.34 | steliosk | well what "full linux" ? glibc ? |
| 20:32.41 | cbrake | anybody tried a http://www.chumby.com/ yet? |
| 20:32.44 | steliosk | s/whatwhats |
| 20:33.00 | Crofton | I have a chumby, habe not tried hacking it thoughj |
| 20:34.08 | prpplague | steliosk: linux vs. uclinux |
| 20:34.24 | cbrake | Crofton: I'm trying to find a simple device to use next to a stero to stream audio to so I can ditch my CD player |
| 20:34.54 | cbrake | planning to use a n770, but need some time to get everything set up |
| 20:35.15 | steliosk | pprpplague : i assume (i.e haven't tested it) the apps should work on uclinux also. Don't think they are that "demanding" |
| 20:35.26 | Crofton | cbrake, I'll check if it can read mp3 from memory stick |
| 20:35.37 | prpplague | cbrake: why not order one of pb's devices? |
| 20:35.44 | prpplague | cbrake: they are most excellent |
| 20:35.49 | cbrake | prpplague: good idea -- you have one? |
| 20:35.59 | cbrake | prpplague: what is the company name again? |
| 20:36.09 | steliosk | pprpplague : i think the zipit may be a solution |
| 20:36.11 | prpplague | cbrake: yea, i got one to look at , and ended up taking it home |
| 20:36.37 | chouimat|busy | prpplague: seems I will have to choose between 2 new jobs (if everything goes well) |

| 20:54.32 | prpplague | chouimat|busy: waster disposal engineer or janitorial services manager? |
| 20:55.08 | chouimat|busy | prpplague: hehe one is embedded developer and the other one is Senior Qt Developer (working from home at 80K) |

| 20:56.22 | chouimat|busy | prpplague: hehe |
| 20:56.30 | steliosk | pprpplague : can't seem tp find a zipit device or my eyes are tired and its time to go to bed :) |

| 20:57.56 | prpplague | http://www.elinux.org/ZipIt |
| 20:58.00 | prpplague | start there |
| 20:59.57 | prpplague | hmm |
| 21:00.07 | prpplague | an area of linux i've not tinkered with |
| 21:00.27 | prpplague | we always did all of our battery stuff inside a custom AVR |
| 21:01.01 | CosmicPenguin | prpplague: don't stress it so bad |
| 21:01.06 | CosmicPenguin | just make a platform driver and you'll be fine |
| 21:01.25 | prpplague | CosmicPenguin: yea, the question is how is the best way to present the information |
| 21:01.35 | CosmicPenguin | you want to see how OLPC does it? |
| 21:01.56 | prpplague | CosmicPenguin: yea, that would be nice, is it in a viewable git repo somewhere? |
| 21:02.13 | CosmicPenguin | It might be upstream |
| 21:02.15 | CosmicPenguin | but here's a link: |
| 21:02.22 | CosmicPenguin | http://dev.laptop.org/git?p=olpc-2.6;a=blob;f=drivers/power/olpc_battery.c;h=2c0db6cd28ccaab0232eacbbee277156847374cc;hb=HEAD |
| 21:02.33 | prpplague | okie dokie thanks, i'll have a look |
| 21:02.36 | CosmicPenguin | drivers/power/ also has the some other battery drivers and a sysfs interface |
| 21:04.15 | prpplague | yea, thats what i was looking at |
| 21:04.31 | prpplague | doesn't appear to be upstream, but handhelds.org has similiar infor |
| 21:04.44 | prpplague | looks like there is a seperate git for a battery tree |
| 21:05.29 | CosmicPenguin | dmwm2 did the work - he borrowed on what was out there |
| 21:05.36 | CosmicPenguin | RP might know more whats the current status of things |
| 21:06.25 | prpplague | CosmicPenguin: yea looks pretty nice |
| 21:06.25 | prpplague | CosmicPenguin: i'll probably use those pieces |
| 21:06.25 | prpplague | CosmicPenguin: gotta find some core patches though |
| 21:06.34 | prpplague | CosmicPenguin: thanks i needed a push in the right direction |
| 21:06.39 | prpplague | CosmicPenguin: that should get me started |
| 21:06.56 | prpplague | CosmicPenguin: we are using the TI bq27350 fuel gauge in our next gen battery |
| 21:07.03 | prpplague | CosmicPenguin: i2c communications |
| 21:07.11 | CosmicPenguin | everybody loves i2c |
| 21:07.38 | ds2 | 1wire! ;) |
| 21:08.41 | prpplague | CosmicPenguin: yea, i2c does well for items like batteries |
| 21:08.45 | prpplague | CosmicPenguin: less wire to connect |

| 21:18.34 | prpplague | CosmicPenguin: doing some digging now |
| 21:18.51 | prpplague | CosmicPenguin: checking to see if its actually in 2.6.23 since i have 2.6.22 |
| 21:19.53 | prpplague | CosmicPenguin: indeed it looks merged upstream into 2.6.23 |
| 21:48.23 | prpplague | CosmicPenguin: looks like the battery stuff is in 2.6.23 and fairly stable |
| 21:48.29 | prpplague | CosmicPenguin: think i'll give it a try |
