morning |

<rkdavis> |
morning |
| [09:15:46] |
<aliosa27> |
morn |
| [09:17:47] |
<rkdavis> |
aliosa27: i presume you know alot about i2c? |
| [09:17:59] |
<aliosa27> |
yessir |
| [09:18:17] |
<rkdavis> |
i need to do some i2c stuff on the zipit BUT i can't use the kernel modules |
| [09:18:34] |
<rkdavis> |
any ideas on how to do it /naked/ without /dev node helpers? |
| [09:18:57] |
<rkdavis> |
i found a snippit for the zipit but no headers for function declarations to show me the way |
| [09:20:37] |
<aliosa27> |
well you wont have a node in /dev till you write a driver for whatever your trying to interface via i2c.. |
| [09:21:16] |
<aliosa27> |
i2c-dev.h is the header you want to look at |
| [09:21:39] |
<rkdavis> |
well i used the modules i2c-core, i2c-pxa and i2c-algo-bit and made the node by hand but nada |
| [09:22:05] |
<rkdavis> |
so i'm going to try it all via userspace if possible with no node |
| [09:22:08] |
<aliosa27> |
does core detect whatever it is you have connected |
| [09:22:23] |
<rkdavis> |
i'm trying to get to the battery chip in the zipit |
| [09:22:36] |
<aliosa27> |
ooo |
| [09:22:40] |
<rkdavis> |
i2c-core etc don't seem to do anything but i get some stuff in /sys |
| [09:23:15] |
<rkdavis> |
thanks to GPSFan i can read some stat stuff but now i need i2c to get the voltage and as i'm in stock i'm limited |
| [09:23:49] |
<aliosa27> |
i have actually never done i2c work in linux without using the kernels wrappers...other kernel'less things I have...but yeh.. |
| [09:24:41] |
<aliosa27> |
do you know the adderss of the chip |
| [09:24:43] |
<rkdavis> |
i remembered yesterday that in stock the sound chip needed init'ing via i2c so looked at the snippit they posted on the wiki but al the important stuff is missing |
| [09:25:04] |
<rkdavis> |
yup according to crazymonkeypants and gpsfan it's 0x55 and the register is 0x02 |
| [09:25:41] |
<aliosa27> |
i2c-dev is the only way to talk to i2c stuff via userspace |
| [09:26:22] |
<aliosa27> |
as im sure udev is not running in the stock image |
| [09:26:30] |
<aliosa27> |
you might have to mknod /dev/i2c-0 |
| [09:26:35] |
<aliosa27> |
.1 , etc |
| [09:26:44] |
<rkdavis> |
http://linux.zipitwireless.com/projects/z2kernel/wiki/WikiStart#AudioRegisterSetup this was the snippit i remembered -- it's on address 0x36 and it's writing but i would imaging the process would be the same, but what Senddata does i dunno and the only references i can find to pI2CBus i can find in google are about X drivers |
| [09:27:11] |
<rkdavis> |
yup i made /dev/i2c-0 c 89 0 -- it complains when i try to read/write to it |
| [09:27:44] |
<rkdavis> |
/dev/i2c-0: No such device or address |
| [09:28:04] |
<rkdavis> |
Module Size Used by Not tainted |
| [09:28:04] |
<rkdavis> |
i2c_pxa 7168 0 |
| [09:28:05] |
<rkdavis> |
i2c_core 17584 1 i2c_pxa |
| [09:28:19] |

<aliosa27> |
and insmodding i2c_core does not output anything? |
| [09:28:47] |
<rkdavis> |
i am not having much luck with the kernel modules so i am trying to do it without, there must be a way as the stock app can read the voltage and it has no drivers in the kernel |
| [09:28:59] |
<rkdavis> |
no errors or anything even when using -v |
| [09:29:44] |
<rkdavis> |
it's actually so annoying as i've seen tons of examples for atmega's and other processors but nothing linux and pxa27x based |
| [09:29:53] |
<aliosa27> |
anything in proc/apm in the stock |
| [09:30:12] |
<rkdavis> |
no /proc/apm in stock |

i have an attiny hooked up via i2c in 2.6.29 on my zipit.. |
| [09:31:10] |
<aliosa27> |
never tried the stock stuffs |
| [09:31:23] |
<rkdavis> |
got some stuff in /sys/bus/i2c and /sys/class/i2c-adapter |
| [09:31:50] |
<aliosa27> |
are you serial'd in |
| [09:32:35] |
<rkdavis> |
nope no serial mod on this zipit (or any actually) |
| [09:33:50] |
<aliosa27> |

so 2 i2c devices |

<rkdavis> |
lrwxrwxrwx 1 root root 0 Jan 1 17:13 device -> ../../../devices/platform/pxa2xx-i2c.1/i2c-1 |

<rkdavis> |
and i2c-0 as well |
| [09:39:50] |
<rkdavis> |
basically device,name,subsystem and uevent |
| [09:43:21] |
<aliosa27> |
i will have to load the stock when i get home |
| [09:44:28] |
<rkdavis> |
i may have busted modules -- these are the ones that ray built, maybe i should just build my own and see if i get anything better although it is annoying because i KNOW it's possible without using the module i just have no idea how and can't find any examples |
| [09:46:08] |
<aliosa27> |
id say you would ither have to beusing the userspace i2c driver or ther eis a phantom driver that is missing from the source tree that gives power info |

| [12:24:03] |
<aliosa27> |
sweet |
| [12:24:41] |
<rkdavis> |
ok it's not very accurate but it gives a sence of the level and when combined with the battery stat gpio's it better than what we had |
| [12:25:26] |
<rkdavis> |
now to combine it all back into m powerdaemon :) ugh i really should comment some of these lines |
| [12:25:28] |
<aliosa27> |
shoot me you code..i want to factor in cpu load/audio |
| [12:25:43] |
<rkdavis> |
ok |
| [12:26:08] |
<rkdavis> |
give me you email address and after the kid and i have watched qi xl i'll send it on it's way |
| [12:26:25] |
<rkdavis> |
it's really dirty code though :) |
| [12:26:33] |
