The MCP3008 is an easily used 10bit, 8 channel, Serial Peripheral Interface (SPI) Analog to Digital Converter. I created an Energia library that can be found here and used to read any of the eight pins with a single call. Conversion is done for voltages between 0 and 3.3 V, including on the CC3200, and results in a integer reading between 0 and 1023. This library is for single ended operation only and uses hardware SPI.
An example is included that demonstrates reading from all 8 channels.
