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 |
