| 00:00.20 | solar | yep. That 2 year mark seems to be the scale or fail turnpoint |
| 00:01.20 | ds2 | the company I moved up here with peaked at about I think 500+ consultants and now they are barely keeping 50ish (if memory serves) and that's over the course of 5 or so years |
| 00:01.56 | g1powermac | $15k as capitol?! |
| 00:02.01 | g1powermac | thats peanuts |
| 00:02.26 | solar | g1powermac_PB: yep. ppl out here are living the dream. |
| 00:02.35 | g1powermac | then again I part own a retail store, which requires insane amounts of capitol |
| 00:02.53 | solar | I keep trying to clue prpplague in. But he seems to like bad weather and non-sexy people |
| 00:03.08 | g1powermac | our store has had an interesting ride |
| 00:03.27 | g1powermac | three years ago we started with peanuts for capital, somehow we made it work |
| 00:03.43 | g1powermac | now our store is three times the size |
| 00:04.00 | solar | my first business adventure involved getting 150k SBC loan. Ruining a friends credit. |
| 00:04.18 | g1powermac | and cash flow that would boggle the minds of most non business owning people |
| 00:04.31 | solar | found sales to be the hardest part of being a geel trying to go solo/independent |
| 00:04.40 | solar | geek ^ |
| 00:04.42 | g1powermac | yea |
| 00:05.01 | g1powermac | that stuff just isn't nice |
| 00:05.23 | pea | sales.. ugh. not me land. |
| 00:05.55 | g1powermac | but yea, my family were the only people working at the store, now we have 8 or so employees |
| 00:06.08 | g1powermac | and this is just selling shoes |
| 00:07.55 | g1powermac | btw, anyone who just can't stand doing engineering anymore, we're always looking for some more sales people ;-) |
| 00:08.13 | g1powermac | of course relocating to kentucky is required ;-) |
| 00:08.39 | ds2 | is there a free still in the package? ;) |
| 00:08.56 | g1powermac | heheh |
| 00:09.09 | g1powermac | you can go walk to the local bourbon distillery ;-) |
| 00:09.20 | ds2 | 'local' == onsite? ;) |
| 00:09.27 | g1powermac | close enough ;-) |
| 00:09.44 | g1powermac | its about a ten minute drive away :-) |
| 00:10.23 | g1powermac | or you can go hit the winery |
| 00:10.33 | ds2 | sick of those around here |
| 00:10.51 | ds2 | taking perfectly good grapes and turning them into spoiled juice ;) |
| 00:11.11 | g1powermac | or if you head up a little further north, you can go hit the Jim Bean distillery ;-) |
| 00:11.27 | ds2 | how far are you from the famous smokey mtns? |
| 00:11.43 | g1powermac | prolly about 4 hour drive |
| 00:11.55 | g1powermac | we're quite a bit north of TN |
| 00:12.20 | ds2 | for some reason I thought you were right off I55 |
| 00:12.39 | g1powermac | nope |
| 00:13.54 | g1powermac | oh yea, forgot, we have two bourbon distilleries in this county |
| 00:14.09 | g1powermac | plus the winery |
| 00:14.39 | g1powermac | and this is a county with less than 20k people in it :-) |
| 00:16.22 | ds2 | does that mean E80 is available? |
| 00:25.41 | g1powermac_PB | nope |
| 00:37.07 | GPSFan | g1powermac: our county has 10+ wineries, 1 distillery, and a brewery, total pop. ~ 30k |
| 00:39.10 | solar | really need more beer |
| 00:39.55 | ds2 | wonder what the stats are for wineries up in Napa |
| 00:40.13 | GPSFan | bazillions... |
| 00:42.11 | solar | the problem there is you still can't walk from one to another to another and home |
| 00:42.26 | solar | somewhere along the lines you are going to end up driving when you really should not be |
| 00:42.47 | ds2 | so move into lucas ranch or something like that ;) |
| 00:43.11 | solar | pubs :) |
| 00:43.15 | GPSFan | of the 10+ wineries in this county 3 are within 2 miles of my house, one right across the street. ;>)) |
| 00:43.44 | solar | I've love the view |
| 00:43.54 | solar | erp. |
| 00:44.05 | ds2 | GPSFan: where are you? |
| 00:44.14 | GPSFan | western colorado. |
| 00:44.40 | ds2 | like where mesa verde is? |
| 00:45.16 | solar | I hear boulder is nice |
| 00:45.30 | GPSFan | not quite that far south. very rural though |
| 00:46.39 | GPSFan | just down the road from: http://www.catchwine.com/wineries/colorado/terror_creek_winery/ |
| 00:48.03 | solar | bang. And here is the map :) http://tinyurl.com/3em84m |
| 00:48.43 | GPSFan | that's in town real close tot the brewery. gotta go cul... |
| 00:50.56 | solar | so that looks about 4.6 fields they have at the one next to you. |
| 00:51.03 | solar | is that a dirt road to get there? |

| 02:17.09 | ds2 | it was just going to be a third serial port |
| 02:17.30 | solar | I'm not run any benchmarks. But I'm almost afraid to admit that on face value it seems gnueabi runs faster than uclibc-oabi |
| 02:17.46 | ds2 | that's what the specs claim |
| 02:19.12 | solar | -uclibcgnueabi we were able to build a few weeks ago right before .30-rc1. So that should be interesting |

| 14:23.09 | CosmicPenguin | yeah - I interviewed with them, but they didn't go through with it because of the commodity stuff |
| 14:25.31 | CosmicPenguin | They had little need for kernel hackers |

| 14:38.02 | libin_v | ARM talks of 8-byte Stack Alignment. http://www.arm.com/support/faqdev/14269.html What is significance of Stack Alignment, when compared to Data Alignment(Word Aligned/Word Addressable memory)? |
| 14:38.05 | CosmicPenguin | If I ever start a company (highly unlikely these days), it would be called Lefthand Software Factory |
| 14:38.30 | chouimat|work | likes Botsnack |
| 14:40.20 | prpplague | libin_v: i don't do much low level assembly, but iirc, the 8 byte stack alignment is to make it easier to work with one 32bit value and one 32bit instruction |
| 14:41.50 | libin_v | prpplague: Could u please elaborate :) |
| 14:44.32 | prpplague | libin_v: functions like LDRD and STRD provide operations based on 2 values, if the values are 32-bit values, you need to have 64-bits available to work with them |
| 14:44.42 | adyer | libin_v: does it really matter? If the compiler is assuming that alignment, you'd better obey it :-) |
| 14:44.51 | chouimat|work | hehe |
| 14:45.48 | libin_v | adyer: My question was In case of Data Alignment we can rearrange the data in a structure.... if members are not aligned? What is the case with Stack Alignment?? |
| 14:47.55 | Chocobo | Has anyone here done anything with Luminary Micro ARM microcontrollers? |
| 14:54.31 | prpplague | Chocobo: iirc there are a couple people that hang out here that have |
| 14:55.41 | Chocobo | Oh man, that would be handy... I am trying to figure out how correctly relocate the interrupt vector table. And if I need to twiddle with the stack pointer after doing so. |

| 15:32.45 | prpplague | CosmicPenguin: yea, this is for a laser scanner |
| 15:32.50 | CosmicPenguin | And I for one, agree - if I can go into say, best buy, scan a barcode and see what the prices are elsewhere... I would totally go for that |
| 15:32.58 | prpplague | CosmicPenguin: trying to decide the best way to set it up in the kernel |
| 15:33.09 | CosmicPenguin | character devices are your friend |
| 15:33.12 | CosmicPenguin | block devices are your enemy |
| 15:33.32 | prpplague | CosmicPenguin: yea, this has several different items |
| 15:33.42 | prpplague | CosmicPenguin: one the data is actually sent via a rs-232 interface |
| 15:34.08 | prpplague | CosmicPenguin: but it has gpio's that control the start of the scan and the good/bad scan indicator |
| 15:34.48 | prpplague | CosmicPenguin: in addition, the scan needs to be inititated via a input scan code |
| 15:34.49 | solar | results from testing eabi on the nail were so pleasing that I'm testing an armv4tl-softfloat-linux-uclibcgnueabi firmware image and it looks good so far. |

| 15:47.27 | prpplague | chouimat|work: yea well, i'd describe it like this, even though you have run off the guy that overflowed the toilet, there is still a @#$ mess in the bathroom |
| 15:48.11 | chouimat|work | prpplague: at least it's just the toilet and not a sewage overflow ;) |

| 15:55.53 | prpplague | my left hand is tingle today |
| 15:57.56 | solar | prpplague: sure one moment |
| 16:02.49 | prpplague | hates owning a house |
| 16:03.25 | prpplague | CosmicPenguin: the developer sold off the remaining lots in out development to a company that is going to build cheap ass houses |
| 16:03.33 | prpplague | CosmicPenguin: about 1/2 the cost of the current homes |
| 16:04.41 | CosmicPenguin | yeah, I have that going on too |
| 16:04.56 | CosmicPenguin | So, you electronics people - I need to find a 4 or 6 inch 8 ohm speaker |
| 16:05.04 | CosmicPenguin | whence do I go on the intertubes? |
| 16:05.06 | prpplague | solar: great, i'll load that on the second partion of my sd card |
| 16:05.45 | prpplague | CosmicPenguin: 8-ohm is pretty common, jameco might be a good source since they have lots of pictures to get a feel for the product |
| 16:06.26 | prpplague | CosmicPenguin: you HOA(or anyone else) been able to do anything about it? |
| 16:06.41 | CosmicPenguin | what do we care? |
| 16:06.51 | solar | prpplague: it wont go directly into X first go. So if you can telnet in or so. |
| 16:07.05 | solar | root (nopass) |
| 16:07.17 | prpplague | CosmicPenguin: devalues your house? |
| 16:07.25 | prpplague | solar: ahh ok |
| 16:07.27 | CosmicPenguin | nah |
| 16:07.46 | CosmicPenguin | it doesn't really - the value of the house is based on comperables, not your neighbor |
| 16:08.54 | prpplague | CosmicPenguin: with a $200k difference in cost? |
| 16:11.06 | CosmicPenguin | our developer was building houses with a 200k difference |
| 16:11.20 | CosmicPenguin | You want to live in a diverse neighborhood |
| 16:11.40 | prpplague | CosmicPenguin: i guess the dynamics are different here |
| 16:11.55 | CosmicPenguin | What you don't want is a comperable house to go in and then have to sell at cut price because of the economy |
| 16:12.02 | prpplague | CosmicPenguin: most of the communities here want a min size and a min value |
| 16:12.08 | CosmicPenguin | far better for you to have a cheaper house that will stay filled |
| 16:12.49 | prpplague | doesn't understand of this house stuff |
| 16:12.54 | CosmicPenguin | I'm just talking about the economics here - the social factor is a different story all together, but we're smart enough to concentrate on what matters |
| 16:13.17 | chouimat|work | prpplague: it's like the rest of the economy ... it go up because people think it will go up |
| 16:13.38 | solar | prpplague: Feedback welcome. |
| 16:13.39 | prpplague | CosmicPenguin: i assume when you say "we're" you are refering to you and your wife |
| 16:13.43 | solar | is off to work. cya |
| 16:13.47 | CosmicPenguin | prpplague: no, you and me... :) |
| 16:13.49 | prpplague | solar: will do |
| 16:14.14 | prpplague | CosmicPenguin: like i said, i don't understand all this house stuff, i'd just as soon not own one, its a total pain in the ass |
| 16:14.36 | CosmicPenguin | Economics are never fun |
| 16:14.48 | prpplague | CosmicPenguin: can you recommend a user space daemon that uses events? |
| 16:14.55 | prpplague | CosmicPenguin: something as an example |
| 16:15.13 | CosmicPenguin | acpid |

| 16:15.27 | prpplague | $5-10 |
| 16:15.35 | prpplague | but they have a min order iirc |
| 16:15.43 | CosmicPenguin | Of what? |

| 16:33.44 | CosmicPenguin | yeah, I found one on partsexpress |
| 16:37.17 | prpplague | CosmicPenguin: if you want to monitor two different /dev/input/eventX , you have to open them both, correct? or is there an easy way to combine them? |
| 16:37.42 | CosmicPenguin | not really - you have to monitor them both |
| 16:37.50 | prpplague | thats what i figured |
| 16:37.52 | CosmicPenguin | THere might be a way to merge them, but i doubt it |
| 16:38.38 | prpplague | just trying to decide if i really want to do this from userspace |
| 16:50.04 | prpplague | CosmicPenguin: userspace will have to monitor /dev/input/event1 for a button push, then trigger a scan on /dev/bctrigger , and watch for the output on /dev/ttySAC0 |
| 16:50.26 | CosmicPenguin | so the userspace needs to trigger a scan? |
| 16:50.33 | CosmicPenguin | can the kernel do that automatically? |
| 16:51.28 | prpplague | CosmicPenguin: well, i was wanting to use the events so they could use any number of keys or event to trigger the scan |
| 16:53.41 | prpplague | CosmicPenguin: if i were to confine it to just the trigger button, i could do it as a simple gpio key module |
| 16:54.42 | prpplague | CosmicPenguin: i could hack the serial driver to add some stuff to do it |

| 16:55.05 | CosmicPenguin | can't he just wait until data shows up? |
| 16:56.13 | prpplague | CosmicPenguin: the user needs to trigger the scan, it may be by clicking an icon, pressing the trigger button, or having set one of the other buttons on the keyboard to trigger the scan |
| 16:57.39 | prpplague | CosmicPenguin: i.e. something similiar to the fancy multimedia keyboards with the "internet" or "media player" buttons |
| 16:59.26 | CosmicPenguin | oh okay |
| 16:59.33 | CosmicPenguin | so you'll need to have the back and forth |
| 17:00.15 | adyer | prpplague: you need some simple event code? there is an 'evtest.c' program floating around that shows how to open and read events. That plus some daemon framework and maybe some magic with select() should get you where you need to go |

| 17:55.02 | Chocobo | hrm. Never heard of that before. Is it a GAS thing? or an ARM ASM thing? |
| 17:55.54 | roxfan | i.e. the "true" form of the instruction is ldr r1, [PC, #delta] |
| 17:56.36 | roxfan | where pc+8+delta contains the value 0x20000000 |

| 18:07.36 | roxfan | ah, so you're assembling, not disassembling |
| 18:08.23 | Chocobo | roxfan, correct. |
| 18:08.41 | roxfan | still i don't see how it makes _reading_ code more complex |
| 18:08.47 | roxfan | but maybe it's just me |
| 18:09.07 | ds2 | 2D or 3D barcode? |
| 18:09.24 | roxfan | 3d? o.O |
| 18:09.39 | ds2 | oops 1D or 2D I mean |
| 18:09.59 | ds2 | 3D would cool though ;) |
| 18:10.03 | roxfan | yeah |
| 18:10.16 | roxfan | would need a reader working in 4d though |
| 18:10.39 | ds2 | little RC plane with a wireless cammera.... |
| 18:10.59 | Chocobo | so ldr r1, =0x20000000, r1 will contain 0x20000000 correct? I guess I don't get "where" that value is when compiled to machine code. |
| 18:11.17 | ds2 | or I suppose multicolored, 2D code is close to a 3D code |
| 18:11.30 | roxfan | it's placed in a so-called literal pool, which is allocated by the assembler |
| 18:11.41 | roxfan | most commonly it's placed after the function |
| 18:11.59 | prpplague | hmm |
| 18:12.13 | roxfan | actually for this instruction you don't need the literal pool |
| 18:12.16 | prpplague | wonders what the heck is going on |
| 18:12.22 | roxfan | so the assembler might optimize it into a mov |

| 18:12.33 | roxfan | *for this constant |
| 18:12.43 | ds2 | Chocobo: the instructions on ARM are exactly 32bit long so to encode a literal 32bit load, it can't be an immediateload unless there are tricks you can play like shifts |

| 18:16.43 | Chocobo | doh! |
| 18:17.50 | Chocobo | huh... that is as easy as .thumb correct? If so then yes... I am also passing -mthumb -mcpu=cortex-m3 to the assembler. |
| 18:18.31 | roxfan | hmm cortex is thumb2 so i think it should support loading high regs... |
| 18:18.53 | roxfan | but you could try a quick hack anyway |
| 18:19.04 | roxfan | ldr r0, [r0,#0] |
| 18:19.07 | roxfan | mov sp, r0 |

| 18:36.10 | Chocobo | See, I am really annoyed right now. I put in the code to load the stack pointer (inline asm) in the ResetISR routine. BUT... it uses a "push" before I load the stack pointer. That is so annoying. |
| 18:36.48 | Chocobo | The luminary chips are pretty sweet eh? I am using the lm3s102... soldered down to an 28-SOIC -> 28-WDIP adapter board. |
| 18:37.40 | roxfan | hmm weird, what does it push? |
| 18:38.24 | roxfan | actually you're supposed to set the initial sp value in the vector table |
| 18:39.25 | roxfan | the first entry |
| 18:40.42 | Chocobo | roxfan, indeed. But I am trying to use the flash loader built into the chip and put my code AFTER the flash loader. you call COMMAND_RUN with the code you want to execute so you need load the SP, and update where you vector interrupt table is. |
| 18:40.53 | Chocobo | 000008b8 <ResetISR>: |
| 18:40.53 | Chocobo | <PROTECTED> |
| 18:41.15 | roxfan | ah |
| 18:41.18 | Chocobo | that is the first line of the ResetISR... |
| 18:42.15 | Chocobo | It doesn't seem like it needs the link register. This isn't a function you return from. |
| 18:42.28 | roxfan | you probably need to tell the compiler about it |
| 18:42.49 | Chocobo | Well I told the linker about it with --entry=ResetISR |
| 18:43.25 | roxfan | ah but the linker can't influence the compiler :) |
| 18:43.29 | Chocobo | your right though, that is a compiler thing |

| 18:46.25 | Chocobo | That worked like a charm. |
| 18:46.25 | roxfan | hehe :) |
| 18:47.50 | Chocobo | hmm, it seems like the code from Luminary is incorrect. Hrmm, maybe not. I guess seeing that the code was intended to run from 0x0, where the SP would be initialized automatically.... it is ok. |
| 18:51.33 | Chocobo | that interesting, when I relocated the interrupt table ... my light no longer blinks. |
| 18:51.47 | Chocobo | I need to GPL my flash loader code too... it is working well. |
| 19:02.10 | Chocobo | Ok, one final question (well... for now) how would you put a function at a specific location? right now I put it in it's own section, and updated the linker script to output that section first. it is sort of ugly really. |
| 19:03.27 | roxfan | i think i've read somwhere that that's what you have to do for gcc toolchain |

| 19:42.17 | prpplague | MonMotha: gonna be pricy |
| 19:42.17 | MothaWork | I know libertas has a SPI-ish option |
| 19:42.35 | MothaWork | price is not necessarily a problem so much as availability in uber-low low volume |
| 19:42.53 | MothaWork | this is an as-needed option, i.e. "pay for it if you want it" |
| 19:43.02 | prpplague | MothaWork: you gonna have an onboard tcp/ip stack? |
| 19:43.07 | MothaWork | lwip, yes |
| 19:43.12 | darkman | i need someone know how to hack computer so i can ask some question ty |
| 19:43.35 | CosmicPenguin | darkman: we cannot help you here |
| 19:43.36 | CosmicPenguin | please move on |
| 19:43.39 | MothaWork | darkman: I think you may have confused your definitions of "hacking" |
| 19:43.42 | adyer | MothaWork: zcomax makes a module with a CF interface (non CF connector tho) |
| 19:43.57 | adyer | MothaWork: haven't used it yet |
| 19:43.59 | MothaWork | adyer: no CF interface available and no external bus, so it would have to get bit-banged |
| 19:44.00 | MothaWork | i.e. ugly |
| 19:44.04 | darkman | ok |
| 19:44.16 | darkman | ty and sorry for this |
| 19:44.18 | prpplague | MothaWork: one sec |
| 19:44.52 | adyer | MothaWork: haven't found and open source friendly marvell module with gspi yet |
| 19:45.10 | MothaWork | adyer: opensource is not required as long as I can get the docs under a reasonable NDA |
| 19:45.11 | prpplague | MothaWork: space/size issues? |
| 19:45.36 | MothaWork | prpplague: would like to keep it to about the size of a SD card minus RF structures and connectors |
| 19:45.40 | MothaWork | but that's not a hard requirement |
| 19:45.56 | prpplague | MothaWork: hmm that is a hard requirement, i would suggest this - http://www.lantronix.com/device-networking/embedded-device-servers/wiport.html |
| 19:46.17 | MothaWork | heh, not "hard" as in it can be bigger if necessary |
| 19:46.29 | prpplague | MothaWork: mouser has them in low qty - http://www.mouser.com/Search/ProductDetail.aspx?qs=P41GyhEsKL5OxQY15%2fpVdQ%3d%3d |
| 19:46.35 | adyer | MothaWork: got ethernet? someone had an embedded ethernet-wifi bridge product |
| 19:46.51 | prpplague | MothaWork: for arm7tdmi, thats what i would recommend |
| 19:47.19 | MothaWork | adyer: I do have ethernet, yes, but it need to be exposed to the outside as well |
| 19:47.30 | MothaWork | prpplague: well, that would work, though it would also replicate most of the functionality of our micro |
| 19:48.06 | prpplague | MothaWork: customer doesn't need to know that, hehe |
| 19:48.17 | MothaWork | prpplague: true |
| 19:48.18 | prpplague | MonMotha: gotta go get the kids, bbiab |
| 19:48.22 | MothaWork | though I'm sure management would raise an eyebrow |
| 19:50.23 | adyer | MothaWork: http://www.testech-elect.com/dpac/embedded-802.11-wireless-module.htm |
| 19:51.58 | MothaWork | adyer: yeah, CF+ |
| 19:52.05 | MothaWork | which I'd have to bit bang |
| 19:52.10 | MothaWork | if you can call that bit banging |
| 19:54.23 | adyer | MothaWork: they have more than CF, look at the table at the bottom, serial, spi, ethernet are all options. They are expensive tho |
| 19:54.49 | MothaWork | adyer: yeah; those are the ones with built in webserver and such |
| 19:54.58 | MothaWork | the procs on those are likely bigger than the uC we're using for the rest of the device |
| 19:55.23 | MothaWork | I suggested an ARM926 (which would give me SDIO), but I have been turned down |
| 19:55.38 | MothaWork | I'm not sure that we'll be able to run all the stuff we want in 64k of RAM, though |
| 19:55.49 | MothaWork | TCP sessions can get kinda RAM happy |
| 19:56.18 | roxfan | can't you use a better cpu if the customer is willing to pay for it anyway? |
| 19:56.24 | adyer | MothaWork: here's the bridge module I was thinking of http://www.wiznet.co.kr/en/pro02.php?&ss[2]=2&page=1&num=57 |
| 19:56.27 | MothaWork | there is no "customer" on this |
| 19:56.37 | MothaWork | this is an internal project to "showcase" a platform |
| 19:57.06 | MothaWork | adyer: I might end up doing a bridge using two PHYs and turning them on and off on the management interface |
| 19:57.12 | MothaWork | so you get wired ethernet or wifi |
| 19:57.15 | MothaWork | the uC has a 10/100 MAC |
| 19:57.42 | MothaWork | I think that beats running USB across a PCB for interconnect in terms of silliness, though |
| 20:03.00 | davidc__ | MothaWork: missed your original question... what were you looking for? |
| 20:05.08 | MothaWork | davidc__: wifi module available in super low quantity that can be attached to an ARM7TDMI |
| 20:05.17 | MothaWork | I don't have SDIO, but I do have SPI or a UART |
| 20:05.20 | davidc__ | MonMotha: ah; thats gonna be a problem |
| 20:05.24 | MothaWork | no external bus, so no CF |
| 20:05.24 | davidc__ | USB :P |
| 20:05.30 | MothaWork | only USB device |
| 20:05.35 | MothaWork | no OTG or Host support |
| 20:05.48 | MothaWork | I guess I could put a SPI USB host on it then hook up a USB wifi device |
| 20:05.51 | MothaWork | that seems even more hackish |
| 20:05.56 | davidc__ | yeah, might be the way to do it.... |
| 20:05.59 | davidc__ | or switch to a new arm |
| 20:06.05 | davidc__ | WIFI is pretty hard to find |
| 20:06.11 | MothaWork | I already requested a different uC and had the request rejected |
| 20:06.21 | MothaWork | though I'm unsure of this uC's ability to do everything desired of it |
| 20:06.32 | MothaWork | and yes, wifi is tough |
| 20:06.34 | MothaWork | I'm not sure why, but it is |
| 20:06.47 | MothaWork | I do have a 10/100 Ethernet MAC |
| 20:06.58 | MothaWork | but the device is to have both wired and wireless |
| 20:07.02 | davidc__ | MonMotha: stuff a linksys router in your box :P |
| 20:07.16 | MothaWork | davidc__: that's essentially what I was thinking of above |
| 20:07.37 | MothaWork | use an ethernet to wifi bridge and hook it up all on the PCB, actually routing ethernet across the PCB between the ethernet PHY and the wifi bridge's inputs |
| 20:07.53 | davidc__ | yup.... well, the only eth/wifi bridges I know are themselves ARM processors |
| 20:07.58 | MothaWork | thing is, all of these modules are WAAAY "smarter" than we want |
| 20:08.00 | davidc__ | well, its not a bridge, but a chip that has the right busses |
| 20:08.11 | davidc__ | to talk to a minipci module |
| 20:08.25 | MothaWork | all we need to be able to do is send/receive wifi frames, and the device needs to handle all the MAC stuff |
| 20:08.33 | MothaWork | s/device/module/ |
| 20:08.44 | MothaWork | purl: don't do that |
| 20:09.01 | MothaWork | gah, it at least responds when you tell it to shut up :) |
| 20:09.15 | davidc__ | MonMotha: yeah, not gonna be pretty. I've seen PCI bit banged before [got enough IO pins? ] :P |
| 20:09.31 | MothaWork | if I'm going there, I might as well just bit bang CF or something |
| 20:09.41 | MothaWork | I could theoretically bit-bang SDIO |
| 20:09.47 | MothaWork | but that's not going to be fun |
| 20:09.54 | davidc__ | yeah... not gonna be a pretty solution no matter how ya work it :/ |
| 20:10.11 | MothaWork | I proposed using an ARM926 running Linux instead. Has SDIO, USB Host, etc. |
| 20:10.23 | MothaWork | but we want to showcase our ARM7TDMI stack |
| 20:10.41 | davidc__ | well, ARM7TDMI code will run nicely on an ARM9 :P |
| 20:10.49 | davidc__ | just scratch off the numbers + don't tell em whats in it |
| 20:10.55 | MothaWork | davidc__: hah |
| 20:11.03 | MothaWork | I think they might notice the huge difference in size of package |
| 20:11.16 | davidc__ | "yes.. that big BGA chip... with all the sdram hanging off the side... definitely ARM7" |
| 20:11.35 | MothaWork | there are some ARM926EJ-S out there with onboard flash and SRAM |
| 20:11.49 | MothaWork | atmel SAM9XE comes to mind |
| 20:11.51 | davidc__ | yup.. I haven't seen one that I can get in low qty though.... |
| 20:12.00 | davidc__ | but I hadn't seen that one yet, so perhaps I'm behind the times :) |
| 20:12.07 | MothaWork | well, I could probably get these since we buy a fair bit of Atmel stuff |
| 20:12.13 | davidc__ | hrm.. Phillips has some ARM7 stuff with USB host IIRC |
| 20:12.22 | MothaWork | I think they may still be in engineering |
| 20:12.29 | MothaWork | davidc__: well, the chip has been explicitly called out |
| 20:12.33 | davidc__ | ah. Joy. |
| 20:12.38 | MothaWork | most of our stack consists of drivers, anyway |
| 20:12.56 | davidc__ | Perhaps electro-therapy of upper management [cattleprod]? |
| 20:13.01 | davidc__ | [might solve your problems] |
| 20:13.10 | MothaWork | yeah AT91SAM9XExxx series is still in development |
| 20:13.29 | MothaWork | amazingly small amount of RAM for some reason |
| 20:13.34 | MothaWork | their SAM7X series has more |
| 20:14.11 | davidc__ | anyhow; just FYI, avoid atheros like then plague. Getting docs out of them is like pulling fingernails. |
| 20:17.51 | MothaWork | well, I have an atheros rep |
| 20:18.05 | MothaWork | and he knows that we won't design it in without full docs up front |
| 20:18.15 | davidc__ | huh... Does he have fangs? and wear a black cloak? |
| 20:18.19 | MothaWork | no |
| 20:18.31 | davidc__ | I dunno.. every time I've dealt with atheros its been miserable |
| 20:18.36 | davidc__ | but perhaps you're higher volume. |
| 20:18.49 | MothaWork | well, they're nowhere near as easy to get basic docs out of as other shave been, for sure |
| 20:18.55 | MothaWork | hell no we're not higher volume :) |
| 20:19.16 | MothaWork | we do buy a fair bit of stuff through him from Atmel, though |
| 20:19.37 | MothaWork | Atmel seems to have exited the wifi realm, though |
| 20:20.17 | davidc__ | anyhow; gotta run. Gonna try and talk apple into replacing this lappy battery and power supply |

| 20:24.11 | prpplague | CosmicPenguin: ok so, i have a button on a gpio, i'm using the gpio_keys class for it |
| 20:24.28 | prpplague | CosmicPenguin: its generating a EV_LED event on the input system |
| 20:25.15 | prpplague | CosmicPenguin: i've created a "generic" EV_LED handler which will be associated with a "generic" led-trigger |
| 20:25.55 | prpplague | CosmicPenguin: the generic led trigger will be tied to my barcode scanner trigger, so it triggers the barcode scan, if it is a good scan it triggers the led |
| 20:26.14 | prpplague | CosmicPenguin: that sound too complexe? |
| 20:30.15 | prpplague | solar: i promise, i've not forgoten about it, just trying to management as much time on it as possible |

| 20:33.19 | MothaWork | ds2: no, it does not |

| 20:34.40 | ds2 | MothaWork: what works as primer? shellac? |
| 20:35.04 | MothaWork | ds2: acrylic primers apparently are good. The latex primers can work, but they sometimes take two coats |
| 20:35.22 | MothaWork | it's similar to preparing wallboard for painting |
| 20:35.54 | ds2 | I'll have to try it... too late for this time... 10 coats and I still see some show through :( |

| 21:45.36 | prpplague | ok, so a generic gpio_keys button generates a EV_LED event, the event is passed to a hardware specific section of code, the section generates the barcode scan request, it either a) receive a good scan signal which calls a led-trigger on the green led or b) times outs and generates a led-trigger on the red led |
| 21:46.31 | prpplague | where the only section that is hardware specific is the generation of the barcode scan request |
| 21:48.32 | prpplague | the only question i really have left is if i should combine the two triggers into one file, or two seperate ones |
