This change enables the use of all channels on the ADC MCP3204 & MCP3208 devices for the Current Loop Temperature Sensors (X300-X399). You can now specify a channel select independent of the X value so all channels on the chip are available. Additionally a new value for W is enabled to allow for single or differential pairs to be selected.
Channel select = "C"
C0 (default), C1, C2, C3... etc up to C7 on MCP3208 device.
Single / Differential select = "W".
W0 (single, default)
W1 (differential)
