Hi - I hope this is the best place to discuss Occidentalis. I had been using an I2C TMP102 temp sensor (http://www.element14.com/community/grou ... spberry-pi) with bootc.net's image (http://www.bootc.net/archives/2012/07/0 ... ezy-image/). I was able to read the TMP102 via the 'senors' utility which I installed via the 'lm-sensors' package.
This week I tried out Occidentalis and was pleased to get the 1-wire DS18B20 temp sensor working with it. However, when I tried to use the I2C TMP102, I received an error message from 'sensors': http://www.element14.com/community/grou ... ment-15937
This is a screenshot:
i2cdetect does see the TMP102 on the bus, but the issue is that the 'sensors' utility reports:
"No sensors found!"
"Make sure you loaded all the kernel drivers you need"
Any ideas would be appreciated. (I'll add a screenshot of i2cdetect from Occidentalis tonight, but it did see a device at 0x48 which is the TMP102's address).
UPDATE: screenshots including hwclock not finding ds1307 located at: https://picasaweb.google.com/1175420012 ... 01I2CIssue#
Thanks,
Drew

Re: Occidentalis, I2C & lm-sensors issue
sounds like theres some other driver cboot has wrapped in that we do not, you should put in an issue on our linux kernel repo at the adafruit github repo
can you do that?
can you do that?

Re: Occidentalis, I2C & lm-sensors issue
Sure, but I don't see the Issues tab on the adafruit account's adafruit-raspberrypi-linux repo:

like I do for the raspberrypi account's linux repo:

Re: Occidentalis, I2C & lm-sensors issue
I think that your adafruit-raspberrypi-linux repo doesn't have Issues enabled. Looking at one of my repos, I see a checkbox for Issues under the Admin section:

Re: Occidentalis, I2C & lm-sensors issue
Comparing with bootc.net's image, I see the problem for TMP102 and DS1307 is that Occidentalis is missing the kernel modules. This is what bootc.net image loads:
root@raspberrypi:~# lsmod
Module Size Used by
tmp102 2571 0
hwmon 1023 1 tmp102
rtc_ds1307 6171 0
root@raspberrypi:~# lsmod
Module Size Used by
tmp102 2571 0
hwmon 1023 1 tmp102
rtc_ds1307 6171 0

Re: Occidentalis, I2C & lm-sensors issue
I haven't tried it yet, but there's some discussion on the Raspberry Pi boards about this topic. They show an example of using the tmp102 without the lm-sensors tools.
