It seems to be working so far. I got this information from SuperMicro,
for their C7X58 and X8SAX motherboards (included here as a direct
transcription from their reply):
Windbond W83795AG, Slave Address=0x2e (0x5c in 8-Bit format)
=============================================================
Fan1/CPU Fan Speed, Offset 0x2e RPM = 84375/Data
Fan2 Fan Speed, Offset 0x2f RPM = 84375/Data
Fan3 Fan Speed, Offset 0x30 RPM = 84375/Data
Fan4 Fan Speed, Offset 0x31 RPM = 84375/Data
Fan5 Fan Speed, Offset 0x32 RPM = 84375/Data
Fan6 Fan Speed, Offset 0x33 RPM = 84375/Data
CPU Voltage, Offset 0x10 Voltage = Data* 0.008
DIMM Voltage, Offset 0x12 Voltage = Data* 0.008
+5V Voltage, Offset 0x13 Voltage = Data* 0.008 * (40/10)
+12V Voltage, Offset 0x14 Voltage = Data* 0.008/(10./66.2)
-12V Voltage, Offset 0x15 Voltage = ((Data*0.008-2.048)/Fact)+2.048
+3.3V Voltage, Offset 0x1c Voltage = Data* 0.024
+3.3VSB Voltage, Offset 0x1d Voltage = Data* 0.024
Battery Voltage, Offset 0x1e Voltage = Data* 0.024
CPU Temperature, Offset 0x26 Temperature = Data
System Temperature, Offset 0x20 Temperature = Data
Chassis Intrusion, Bank 0, Offset 0x46, BitMask 0x40 1 = Bad, 0 =
Good
(Clear Bit: Bank 0, Offset 0x4d, BitMask 0x80)
Power Supply Failure, GP31(From W83627DHG-P) 1 = Good, 0 = Bad
Is there any way to access the last two? Do we export the GPIO pins of
these chips through sysfs at all?
Also, I am wondering what they mean with "Fact" in the -12V reading.
