Board Temperature monitoring

Purpose

Monitor periodically (~ 1Hz) the internal temperature of the micro-controller as well as the FEB64 board temperature using SSTProtocol

Description

For the uC, the temperature is readout through its internal ADC[8]. For board temperature, dedicated device ADT7486A used for the remote temperature has an internal sensor (see External Temperature (SST)), this device uses a particular SSTProtocol.

Condition

Board shutdown in case of over limit measurements Around 50degC for the uC and the Board temperature See FEB64 Limit parameters
