- Kernel driver adt7411
- =====================
- Supported chips:
- * Analog Devices ADT7411
- Prefix: 'adt7411'
- Addresses scanned: 0x48, 0x4a, 0x4b
- Datasheet: Publicly available at the Analog Devices website
- Author: Wolfram Sang (based on adt7470 by Darrick J. Wong)
- 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.
