Initialise

Initialise
Confgures the SPI bus ready for communications and initialises the MCP356X device. Returns true if device is responding to commands. 
- BOOL Return


SampleADC

SampleADC
Performs a single ADC sample and returns the result as a 24-bit value 
- BYTE PositiveChannel
0=CH0 - 7=CH7, 8=GND, 9=VDD, 11=REF+, 12=REF-, 13=TP, 14=TM, 15=VCM 
- BYTE NegativeChannel
0=CH0 - 7=CH7, 8=GND, 9=VDD, 11=REF+, 12=REF-, 13=TP, 14=TM, 15=VCM 
- LONG Return


SetGainCalibration

SetGainCalibration
Allows the device offset to be entered allowing for accurate readings. 
- ULONG Gain
Default 800000 = Gain of 1X 
- VOID Return


SetOffsetCalibration

SetOffsetCalibration
Allows the device offset to be entered allowing for accurate readings. 
- LONG Offset
 
- VOID Return
