| 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. | |
| sysfs-Interface | |
| --------------- | |
| in0_input - vdd voltage input | |
| in[1-8]_input - analog 1-8 input | |
| temp1_input - temperature input | |
| Besides standard interfaces, this driver adds (0 = off, 1 = on): | |
| 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 | |
| Notes | |
| ----- | |
| SPI, external temperature sensor and limit registers are not supported yet. |
