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.
