1 Kernel driver adt7411 2 ===================== 3 4 Supported chips: 5 * Analog Devices ADT7411 6 Prefix: 'adt7411' 7 Addresses scanned: 0x48, 0x4a, 0x4b 8 Datasheet: Publicly available at the Analog Devices website 9 10 Author: Wolfram Sang (based on adt7470 by Darrick J. Wong) 11 12 Description 13 ----------- 14 15 This driver implements support for the Analog Devices ADT7411 chip. There may 16 be other chips that implement this interface. 17 18 The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an 19 SPI-compatible 4-wire interface. It provides a 10-bit analog to digital 20 converter which measures 1 temperature, vdd and 8 input voltages. It has an 21 internal temperature sensor, but an external one can also be connected (one 22 loses 2 inputs then). There are high- and low-limit registers for all inputs. 23 24 Check the datasheet for details. 25 26 sysfs-Interface 27 --------------- 28 29 in0_input - vdd voltage input 30 in[1-8]_input - analog 1-8 input 31 temp1_input - temperature input 32 33 Besides standard interfaces, this driver adds (0 = off, 1 = on): 34 35 adc_ref_vdd - Use vdd as reference instead of 2.25 V 36 fast_sampling - Sample at 22.5 kHz instead of 1.4 kHz, but drop filters 37 no_average - Turn off averaging over 16 samples 38 39 Notes 40 ----- 41 42 SPI, external temperature sensor and limit registers are not supported yet.
