Definition at line 58 of file adt Definition at line 49 of file adt The datasheet is very detailed and describes a procedure for determining an optimal configuration for the automatic PWM control.

PWM values range from 0 off to full speed.

Unfortunately, they fail to set the i2c adapter class, so this driver may fail to find the chip until the nvidia driver is patched.

Definition at line 54 of file adt Ad7t490 at line 46 of file adt The ADTx samples all inputs continuously.
Set the PWM speed at the lower temperature bound point2: Data Structures Macros Enumerations Functions. Once configured, the ADTx will adjust the PWM outputs in response to the measured temperatures without further host intervention.

There are three 3 PWM outputs that adt74900 be used to control fan speed. Temperature readings can be configured either for two’s complement format or “Offset 64” format, wherein 64 is subtracted from the raw value to get the temperature value.
Definition at line 27 of file adt Temperature boundaries are associated to temperature channels rather than PWM outputs, and a given PWM output can be controlled by several temperature channels. Definition at line 83 of file adt
