TMP43X(4D) Devices TMP43X(4D)

NAME

tmp43x - tmp401, 411, 43x series I2C temperature sensor driver

SYNOPSIS

/dev/sensors/temperature/i2c/tmp43x*

DESCRIPTION

The tmp43x driver supports the Texas Instruments TMP401, TMP411,
TMP431, TMP432, and TMP435 I2C temperature sensor devices. All devices
support a "local" sensor and at least one remote sensor called
"remote1". The TMP432 supports a second remote temperature sensor
called "remote2".

All of the sensors are registered with the kernel sensor framework and
an interface to them is provied by ksensor(4D). The temperature is
measured in units of 1/16th of a degree Celsius and the devices
generally have +/-1 degree Celsius of accuracy.

Temperature information is available to the system through the fault
management architecture (FMA). The file system location and
programming interface to the tmp43x temperature sensors are considered
volatile.
