Thermocouple TypeK component
A component matchin the Matrix EBM008 thermocouple board. As well as an interface to a standard TypeK thermocouple, this also includes a thermistor that is used for cold junction compensation.
Examples
This demo reads the temperature from both the thermistor and thermocouple.
The thermocouple requires calibration from the thermistor to read accurate temperatures.
This is achieved by holding any switch on PORTD to set adjust the thermocouple to ambient.
