Description
|
|
-----------
|
|
|
|
This driver implements support for the Analog Devices ADT7411 chip. There may
|
|
be other chips that implement this interface.
|
|
|
|
The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
|
|
SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
|
|
converter which measures 1 temperature, vdd and 8 input voltages. It has an
|
|
internal temperature sensor, but an external one can also be connected (one
|
|
loses 2 inputs then). There are high- and low-limit registers for all inputs.
|
|
|
|
Check the datasheet for details.

|
adc_ref_vdd Use vdd as reference instead of 2.25 V
|
|
fast_sampling Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
|
|
no_average Turn off averaging over 16 samples
