Due to hardware limitations, fresh sensor data is only available every 2 seconds.
For most of the Winbond chips (identified with a * above), the flags configuration option can be specified to select the type of temperature sensor:
flags | Sensor Type |
0 |
Thermistor diode (Power-On default) |
1 |
Pentium-II diode |
2 |
2N3904 Bipolar |
4 |
Thermistor diode |
There are currently no known pnpbios IDs assigned to LM chips.
