1 Kernel driver tmp401 2 ==================== 3 4 Supported chips: 5 * Texas Instruments TMP401 6 Prefix: 'tmp401' 7 Addresses scanned: I2C 0x4c 8 Datasheet: http://focus.ti.com/docs/prod/folders/print/tmp401.html 9 * Texas Instruments TMP411 10 Prefix: 'tmp411' 11 Addresses scanned: I2C 0x4c 12 Datasheet: http://focus.ti.com/docs/prod/folders/print/tmp411.html 13 14 Authors: 15 Hans de Goede <hdegoede@redhat.com> 16 Andre Prendel <andre.prendel@gmx.de> 17 18 Description 19 ----------- 20 21 This driver implements support for Texas Instruments TMP401 and 22 TMP411 chips. These chips implements one remote and one local 23 temperature sensor. Temperature is measured in degrees 24 Celsius. Resolution of the remote sensor is 0.0625 degree. Local 25 sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not 26 supported by the driver so far, so using the default resolution of 0.5 27 degree). 28 29 The driver provides the common sysfs-interface for temperatures (see 30 /Documentation/hwmon/sysfs-interface under Temperatures). 31 32 The TMP411 chip is compatible with TMP401. It provides some additional 33 features. 34 35 * Minimum and Maximum temperature measured since power-on, chip-reset 36 37 Exported via sysfs attributes tempX_lowest and tempX_highest. 38 39 * Reset of historical minimum/maximum temperature measurements 40 41 Exported via sysfs attribute temp_reset_history. Writing 1 to this 42 file triggers a reset.
