| 00:00.27 | chouimat | prpplague: you know the nicest email I got today ... it was a job proposition from one of the competitor of the company I used to work for ... I will have to wait a few months before that |
| 00:03.10 | g1powermac_EPC | and no one wants to manage a shoe store, ehh? ;-) |
| 00:07.52 | chouimat | g1powermac_EPC: hehe |
| 00:08.35 | g1powermac_EPC | c'mon, you even get free room and board in our cardboard recycling dumpster ;-) |
| 00:10.10 | chouimat | hehe ... |
| 00:10.41 | g1powermac_EPC | heck, actually, its pretty spacious, the thing is huge |
| 00:10.50 | chouimat | :) |
| 00:10.56 | g1powermac_EPC | prolly rivals some NYC apartments ;-) |
| 00:11.06 | chouimat | you mean broom closet |
| 00:11.17 | g1powermac_EPC | hehe |
| 00:11.37 | g1powermac_EPC | just have to watch for incoming cardboard ;-) |
| 00:11.58 | g1powermac_EPC | and the truck to pickup the cardboard. . .could be a bit painful ;-) |
| 00:19.01 | chouimat | hehe |
| 00:29.10 | g1powermac_EPC | hmm, interesting, seems some people have a linux kernel booting on the iphone |
| 00:37.41 | g1powermac_EPC | wonders how hard it would be to interface to the iphone lcd |
| 00:40.08 | g1powermac_EPC | they're really cheap on ebay |
| 00:49.24 | MonMotha | g1powermac_EPC: not usually complicated IF you get get some form of focs |
| 00:49.26 | MonMotha | *docs |
| 00:49.40 | g1powermac_EPC | yea, thats the issue |
| 00:49.51 | g1powermac_EPC | not seeing much out there |
| 00:50.42 | g1powermac_EPC | holy moly |
| 00:51.00 | g1powermac_EPC | the sparkfun guys made a gps module to connect to the itouch and the iphone without gps |
| 01:02.55 | prpplague | g1powermac_EPC: the iphone is based on similar cores to the s3c24xxxx stuff |
| 01:03.13 | g1powermac_EPC | ahh |
| 01:03.35 | g1powermac_EPC | so you'd think the lcd interface would be similar? |
| 01:13.51 | chouimat | ok time to go read something |
| 01:23.02 | MonMotha | well, most LCDs are interfaced in similar ways. It's just a matter of getting all the numbers you need to plug in to some registers |
| 01:24.44 | g1powermac_EPC | according to the iphone linux site, the lcd uses I2C from some control stuff |
| 01:25.03 | g1powermac_EPC | SPI too |
| 01:25.23 | g1powermac_EPC | would love to figure out how to interface with the multitouch ts |
| 01:25.51 | roxfan | afaik multitouch uses a separate controller |
| 01:26.07 | roxfan | and its firmware is loaded by iphone kernel |
| 01:26.07 | g1powermac_EPC | yea |
| 01:27.05 | ds2 | hmmm |
| 01:27.56 | ds2 | those 0.88 cones are nice |
| 01:34.07 | g1powermac_EPC | hmm |
| 01:40.37 | MonMotha | g1powermac: I2C for control is common. The interface is normally SPI for small LCDs (like used on normal cell phones at ~160x160 resolution) or some form of parallel input |
| 01:41.05 | g1powermac_EPC | hmm |
| 01:41.06 | MonMotha | smaller panels are usually TTL/CMOS level, and sometimes RGB are time multiplexed onto the line (so one pixel is 3 clocks) |
| 01:41.30 | MonMotha | big panels (>480 lines) are usually LVDS and frequently have that time multiplexing |
| 01:42.22 | g1powermac_EPC | ahh |

| 18:49.36 | roxfan | what libraries do you have? |
| 18:51.05 | g1powermac_EPC | this lcd screen's spi interface is just odd |
| 18:51.35 | g1powermac_EPC | it actually wants a device id number transmitted in a start byte with each packet |
| 18:52.21 | chiques-2 | I have debug12.h, hcs12.h, vectors12.h and lcd.h |
| 18:55.59 | chiques-2 | I think I found one in lcd.h |
| 18:58.58 | g1powermac_EPC | hmm, the one chip I want to use with the lcd on the spi bus can handle daisy chaining |
| 18:59.17 | g1powermac_EPC | but this lcd's datasheet just doesn't talk much about the spi interface |
