Macro reference

Initialise

	Initialise
Configures the I2C bus ready for communications.
- VOID	Return

ReadReference_Float

	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.
- FLOAT	Return

ReadReference_Int

	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.
- INT	Return

ReadThermocouple_Float

	ReadThermocouple_Float
Returns the thermocouple temperature from the last sample as a floating point value. Use Sample first, which samples both reference & themocouple temperatures.
- FLOAT	Return

ReadThermocouple_Int

	ReadThermocouple_Int
Returns the thermocouple temperature from the last sample as an integer value. Use Sample first, which samples both reference & themocouple temperatures.
- INT	Return

Read_N_Registers

	Read_N_Registers
Reads a number of sequential bytes starting from the specified register
- BYTE	Address

- BYTE	Data

- BYTE	Count

- VOID	Return

Read_Register

	Read_Register
Reads a byte from a register
- BYTE	Address

- BYTE	Return

Sample

	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.
- BYTE	Return

Write_N_Registers

	Write_N_Registers
Writes a set of data values to a sequential registers on the accelerometer
- BYTE	Start_Reg

- BYTE	Num_Regs

- STRING	Data

- VOID	Return

Write_Register

	Write_Register
Writes a byte to a register
- BYTE	Address

- BYTE	Data

- VOID	Return

Property reference

	Properties
	Thermocouple Properties
	Thermocouple Type
Thermocouple type. Selects which type of thermocouple the IC works with.
	Filter Coefficients
Digitial filter selection. The higher the number the better the filter. Results more stable but take longer to update.
	Unit
Select Temperature results to be celsius or fahrenheit
	I2C Properties
	Address
Address ranges 0x60 - 0x67 (96 - 103)
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Simulation
	Simulate Comms
