> 2.8.0 from the web page. Could you download sensors-detect CVS and give it a try?

There is a LM device at 0x19. The devices from 0x20 to 0x23 are really mysterious. If you are curious, you could run "i2cdump 0 0x20" and see if it returns anything interesting. Warning! We don't have the slightest idea on what this device can be, so running this command is potentially dangerous. Do as you want, as I explained in the previous e-mail. > I have been told that "Sensor D1 reads the CPU die temperature, the > local sensor reads the LM83's own temperature.

FYI, the matchings are: temp1 local temp2 D1 temp3 D2 temp4 D3 Temp1 has to be the LMXX own temperature, temp2-4 can be anything remote or nothing at all. > In my testing I have seen that temp1 is fairly stable 36-37.

The LM82 is basically a cut down LM83 with a singe remote temperature instead of 3. Do you have any reason to believe you must have a real LM83, apart from the fact that sensors-detect told you so? > > Are these four entries correct?

Do: echo 80 > /proc/sys/dev/sensors/lm83-i2c-0-19/temp1 echo 90 > /proc/sys/dev/sensors/lm83-i2c-0-19/temp2 echo 100 > /proc/sys/dev/sensors/lm83-i2c-0-19/temp3 echo 110 > /proc/sys/dev/sensors/lm83-i2c-0-19/temp4 Wait a few seconds, and run "i2cdump 0 0x19 b" again. I should be able to conclude. > Are the output from the commands I tried correct? seems strange! Unless hexadecimal is your natural alphabet and you speak the sensor chip language every day, yes, seems strange. Normally, users don't have to deal with this ;) Thanks a lot for reporting! -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
