Detailed Description

Driver for the CC2538 on-chip temperature sensor.

This driver can return the raw as well as the converted value of the sensor reading. This is controlled by the type argument of the sensor driver's value() function. The choices for the type argument are:

• CC2538_SENSORS_VALUE_TYPE_RAW (value() returns the raw reading)
• CC2538_SENSORS_VALUE_TYPE_CONVERTED (value() returns degrees mC)
