Thermocouple ( MCP960X) component
Component to interface the MCP960X IC from Microchip. Uses a standard 2-wire I2C interface to connect to the IC and collect the temperature. IC available in different versions to suit different thermocouple types.
Examples
Here is a basic example to display both the thermocouple temperature and IC surface temperature.
Sim Demo
Downloadable macro reference
ReadReference_Int
Returns the Reference (IC die) temperature from the last sample as an integer value.
Use Sample first, which samples both reference & themocouple temperatures.
Parameters
- This macro has no parameters
Return value
ReadReference_Float
Returns the reference (IC die) temperature from the last sample as a floating point.
Use Sample first, which samples both reference & themocouple temperatures.
Parameters
- This macro has no parameters
Return value
Sample
Must be called before any of the Read functions.
Reads the memory of the MCP9600/1 IC. Returns 0 for 9600. Checks for errors, MCP9601 only.
Returns: 0 = OK, 1 = O/ C Themocouple & 2=S/C Themocouple.
Parameters
- This macro has no parameters
Return value
ReadThermocouple_Int
Returns the thermocouple temperature from the last sample as an integer value.
Use Sample first, which samples both reference & themocouple temperatures.
Parameters
- This macro has no parameters
Return value
ReadThermocouple_Float
Returns the thermocouple temperature from the last sample as a floating point value.
Use Sample first, which samples both reference & themocouple temperatures.
Parameters
- This macro has no parameters
Return value
Initialise
Configures the I2C bus ready for communications.
Parameters
- This macro has no parameters
Return value
- This call does not return a value
