| 21:13.22 | T0mW | I've dumped the kernel keymap with dumpkeys with the intention of mapping some zipit keys to Fx (function keys). Anyone know where I can get detailed information about the kernel keymapping? |
| 21:13.54 | T0mW | I know where the keymap is in the source, but there is something called a string table? |
| 21:14.31 | CosmicPenguin | keymaps are black voodoo |
| 21:14.41 | T0mW | no sh~t, heh |
| 21:15.22 | T0mW | as I have found out. I have a key mapped as F10, it appears to give the new code when I push it, but, midnite commander seems to translate it into something else. |
| 21:15.40 | CosmicPenguin | technology from the dark ages has a tendency t odo that |
| 21:16.06 | T0mW | showkey only gives the raw keycode, what could I use to see the translated keycode (or string)? |
| 21:17.01 | T0mW | I'm down to the final polishing, adding in missing keyboard keys: function F1..F10 |
| 21:18.28 | T0mW | I can map an individual keycode over to another key, but I looks like a key, such as F1, responds by sending ESC-something (two chars), that doesn't seem to be working (string table prob with my kernel?) |

| 21:43.39 | T0mW | here is one problem 2.4 kernel + 2.6.11 headers where #define NR_KEYS 256 in the headers and it is actually 128 in kernel headers (OE sillyness) |
| 21:53.10 | jbevren | T0mW: what's the preferred method of using the console? (I thought /dev/console was the way to g0 |
| 21:54.10 | T0mW | jbevren: you are asking someone who has always shied away from reading into linux/driver/char/console.c |
| 21:54.12 | T0mW | heh |
| 21:54.46 | T0mW | jbevren: reading that code always gives me a headache |
| 21:56.18 | jbevren | hehe |
| 21:56.32 | jbevren | that said, I'd only use it for char IO |
| 21:56.33 | jbevren | I doubt I'd ever find myself IOCTL'ing it |
| 21:58.19 | T0mW | jbevren: well, it looks like I cannot avoid correcting the 2.4 kernel header problem in OpenEmbedded. I'm using a hacked version of 2.6.11 headers and that has been giving me grief with threads (it wants to use NPTL which is not not in my kernel). |
| 21:58.55 | T0mW | jbevren: one good thing about working with the Zipit is that I'm gaining a lot of experience with the kernel |
| 21:59.11 | jbevren | tom: I see. I really need to serial-hack my zipit some time heh |
| 21:59.26 | jbevren | with any luck I'll have better progress than I did with the SD card attempt |
| 21:59.40 | jbevren | (I lost one of the SMT resistors in a solder blob) |
| 21:59.49 | T0mW | jbevren: If you are not challenged by a soldering iron, I'm now selling only the boards. |
| 22:00.00 | jbevren | I actually have a real one now |
| 22:00.09 | jbevren | a weller low-end tmep controlled unit |
| 22:00.11 | jbevren | its so nice :D |
| 22:00.23 | jbevren | how much are the boards (or link?) |
| 22:00.50 | jbevren | http://www.sparkfun.com/commerce/product_info.php?products_id=8291 <- this could be fun |
| 22:00.50 | T0mW | jbevren: yeah, retired my old weller tc201 40W in favor of a $300+ MetCal iron. Real nice setup. |
| 22:00.58 | jbevren | nod, this is a $150ish iron |
| 22:01.03 | jbevren | I have 800 and 700 tips |
| 22:01.07 | jbevren | both fine and large |
| 22:01.41 | T0mW | jbevren: I know that the tools don't make the mechanic, but, when you do have nice tools, and, know how to use them. Well... |
| 22:01.48 | jbevren | I could stuff one of those GPS modules into a zipit hehe |
| 22:02.02 | jbevren | right |
| 22:02.09 | jbevren | its like someone told me about musical instruments |
| 22:02.15 | jbevren | they dont make a musician great |
| 22:02.24 | jbevren | but if you only have a so-so instrument, you'll only ever be so-so |
| 22:02.32 | T0mW | jbevren: too bad they did not make more I/O pins available inside that Zipit, it could have been so much more fun adding stuff into it on the SPI. |
| 22:02.42 | jbevren | yeah |
| 22:02.49 | jbevren | I really wish SPI were extended |
| 22:03.02 | jbevren | I did see the other day, a i2c/spi bridge |
| 22:03.07 | jbevren | but i2c's fairly limited on bitrate |
| 22:03.24 | T0mW | jbevren: there is one other Port Pin, but you have to go to lengths to use it. You really need a microscope to attach a wire to it. |
| 22:03.37 | jbevren | ah, under the edge? |
| 22:03.45 | T0mW | jbevren: under the keyboard |
| 22:03.54 | jbevren | back side of pcb? |
| 22:04.03 | jbevren | that brings up a question. Is the keyboard all GPIO? |
| 22:04.15 | T0mW | on the keyboard side of the PCB there is a feed thru to an unused GPIO pin |
| 22:04.25 | jbevren | ah |
| 22:04.35 | T0mW | jbevren: hey |
| 22:04.41 | jbevren | makes me wish I had a zipit here |
| 22:04.44 | jbevren | sadly I only have a pepperpad |
| 22:04.53 | jbevren | hey? |
| 22:04.59 | T0mW | jbevren: I wonder if the keyboard port can be used somehow... |
| 22:05.07 | jbevren | well |
| 22:05.13 | jbevren | its a ribbon cable |
| 22:05.16 | jbevren | not an encoded kbd |
| 22:05.22 | jbevren | so I figure its GPIO |
| 22:05.29 | jbevren | like, for example, the commodore 64 kbd |
| 22:05.35 | jbevren | thats read using 16 gpio's |
| 22:05.57 | jbevren | is the zipit source browsable online? |
| 22:06.04 | jbevren | I'm not at home lol |
| 22:06.24 | prpplague | T0mW: isn't the zipit keyboard a gpio matrix? |
| 22:06.29 | jbevren | you'd need another console (serial, net, whatever) |
| 22:06.32 | jbevren | prpplague: thats my guess |
| 22:06.49 | T0mW | GPIO PA7 and PB3 go to the cover switch... |
| 22:07.00 | jbevren | two lines to the switch? hrm |
| 22:07.06 | T0mW | if you do not use the cover switch to detect a lid closure... |
| 22:07.15 | jbevren | nod |
| 22:07.21 | jbevren | my zipit is dunkles+zipitpet |
| 22:07.24 | prpplague | hmm |
| 22:07.25 | jbevren | I havent modified too much |
| 22:07.29 | prpplague | not seeing the info on the keyboard |
| 22:07.38 | jbevren | prpplague: keyboard driver source |
| 22:07.38 | T0mW | jbevren: you *could* remove the cover switch from the pcb and solder to that pad... |
| 22:08.13 | T0mW | prpplague: I don't think it is a GPIO matrix, but a programmed keyscanner in the hardware? |
| 22:08.32 | T0mW | automagic keyscanner in the CPU hardware? |
| 22:09.01 | prpplague | T0mW: hmm, but i'm sure the lines are multiplex |
| 22:09.30 | T0mW | jbevren: I've often thought that if you could get just two GPIOs free, then you could use those as a 4 line decoder to select which SPI device you're talking to... |
| 22:09.43 | jbevren | T0mW: right |
| 22:10.00 | prpplague | yea looks like it has a 8x8 keypad matrix |
| 22:10.11 | T0mW | actually, three devices: 0==NOT CONNECTED, 1=SDCARD, 2=.. 3=.. |
| 22:10.14 | jbevren | T0mW: if the lines hook to the keypad direct from the cpu, they're most likely muxed |
| 22:10.21 | jbevren | T0mW: right |
| 22:10.36 | jbevren | T0mW: or conversely, use the GPIO lines as a device select |
| 22:10.38 | T0mW | jbevren: currently, the cover switch is not used in the kernel |
| 22:10.42 | prpplague | yea they can be used for gpios |
| 22:10.45 | jbevren | adding one pin to select give syou 4 devices on the chain |
| 22:10.55 | jbevren | T0mW: dunkles' software uses it |
| 22:11.04 | jbevren | if the lid switch is pressed, it boots to initrd instead of cramfs |
| 22:11.09 | jbevren | good recovery option:) |
| 22:11.15 | prpplague | T0mW: what you could do, is use a atmega48 to do the keypad decoding and send it via spi using some gpios |
| 22:11.17 | T0mW | Who is "dunkle"? TomW's software doesn't use it. |
| 22:11.25 | jbevren | adam Dunkles (I think?) |
| 22:11.29 | jbevren | no wait, he did continki |
| 22:11.30 | prpplague | T0mW: leaving the rest of the gpios for generic usage |
| 22:11.41 | jbevren | who's the adam guy that modified zipitpet's original ahck? |
| 22:11.55 | prpplague | T0mW: is there a schematic generated for the zipit? |
| 22:12.04 | prpplague | T0mW: didn't you tone it out? |
| 22:12.23 | CosmicPenguin | blah |
| 22:12.29 | prpplague | CosmicPenguin: hehe |
| 22:12.38 | jbevren | cos; yeah yeah, zipit blah hehe |
| 22:12.45 | CosmicPenguin | I don't have any enthusasim to work - my office is all packed |
| 22:12.52 | jbevren | ah |
| 22:12.55 | prpplague | CosmicPenguin: you move on monday? |
| 22:13.01 | jbevren | I'm sorting trees for shipping for work |
| 22:13.06 | CosmicPenguin | Tommorrow is the last day |
| 22:13.06 | jbevren | taking an extended vacation from IT |
| 22:13.09 | CosmicPenguin | Move day is on friday |
| 22:13.50 | prpplague | CosmicPenguin: oh? |
| 22:13.54 | prpplague | CosmicPenguin: going to tibet? |
| 22:14.31 | CosmicPenguin | moving offices |
| 22:14.48 | CosmicPenguin | pretty sure I told you guy that, didn't I? |
| 22:15.38 | T0mW`busy | phone |
| 22:16.04 | prpplague | CosmicPenguin: i meant about "extended vacation from IT" |
| 22:16.15 | CosmicPenguin | That wasn't me |
| 22:16.25 | CosmicPenguin | They're going to have to scrap my festering corpse out of this seat |
| 22:16.32 | jbevren | prpplague: that's me hehe |
| 22:16.34 | prpplague | hehe |
| 22:16.54 | jbevren | I'm tired of dealing with retards and a//holes |
| 22:17.08 | jbevren | so I work in a business where there is real accountability for everything |
| 22:17.10 | jbevren | no BS |
| 22:17.16 | jbevren | just work and things actually getting done :) |
| 22:19.24 | prpplague | T0mW`busy: so add a atmega48 to do the keyboard martrix, you'd need 4 gpios to do the spi keyboard interface, but you'd gain 4 gpios from keyboard matrix, plus you could drive the led and the open/close switch from the atmega , so you'd end up with about 6 direct gpios |
| 22:21.13 | jbevren | but if you already have the MMC hack, you only need to add one GPIO to select the atMega |
| 22:21.48 | jbevren | there's one bug I read about with MMC's.. some require that you shift 8 times after deselecting them |
| 22:22.29 | prpplague | jbevren: yea, you'd probably want the keyboard on a dedicated spi for the response time |
| 22:23.53 | jbevren | shrug |
| 22:23.57 | jbevren | probably.. |
| 22:24.05 | jbevren | but if the atmega can buffer, its less of an issue |
| 22:24.11 | jbevren | Ive worked with systems that use PIO IDE |
| 22:24.19 | jbevren | and uninterruptable routines ;) |
| 22:24.29 | jbevren | linux can be nasty, but as long as youre not diskbound in the background, its ok |
| 22:25.01 | prpplague | jbevren: yea, the design we have will buffer 128 characters |
| 22:25.17 | prpplague | jbevren: but we really found you needed to the dedicated spi |
| 22:25.37 | prpplague | the atmega48 is pretty small and pretty thin |
| 22:26.13 | jbevren | a random side note.. a friend and I need to make a ps/2 to parallel adaptor |
| 22:26.23 | jbevren | dunno how old of a system you've worked with.. :) |
| 22:26.36 | jbevren | but older cp/m systems used a parallel ascii keyboard for input |
| 22:27.10 | prpplague | jbevren: parallel in what format? just a 8 bit data line with a clock? |
| 22:27.13 | jbevren | prpplague: a friend has such a system, which runs four concurrent copies of cp/m via a hypervisor hehe |
| 22:27.22 | jbevren | 8 bit data with two lines (available and ack) |
| 22:27.31 | jbevren | not too dissimilar from old parallel printer protocol |
| 22:27.45 | prpplague | jbevren: uh, gotta have a clock in there somewhere? |
| 22:28.21 | jbevren | whyso? The parallel data gets posted on d0:7 and is cleared when the system strobes ACK. (ack would be the closest thing to a clock) |
| 22:28.37 | jbevren | when a new key is ready, the 'rdy' line is asserted |
| 22:28.53 | prpplague | jbevren: ahh the rdy is acting like the clock |
| 22:29.04 | jbevren | nod, like paralle printer protocol |
| 22:29.09 | prpplague | jbevren: easy enough to do with a atmega48 |
| 22:29.16 | jbevren | I know it can be done with a simple IC like a SX20 or mega48 |
| 22:29.24 | jbevren | I have sx20's on hand lol |
| 22:29.45 | jbevren | and with the builtin 1mhz osc on the sx20, it makes a nice single-chip solution mwahah :) |
| 22:30.05 | jbevren | I dont know much of anything about the atmega's |
| 22:32.07 | prpplague | pertty darn easy to dev under linux for them |
| 22:32.08 | prpplague | all c |
| 22:34.02 | jbevren | cool |
| 22:34.21 | jbevren | do they have anything in the range of 16 IOs? |
| 22:34.29 | jbevren | I know its a pretty dumb question :) |
| 22:34.45 | jbevren | but that's a goal. Single chip is preferred, internal clock |
| 22:35.54 | jbevren | oh, didnt see that he left lol |
