In this entry I will demonstrate how to interface the MCP3008; an SPI-based analog to digital converter (ADC) integrated chip; to the Raspberry Pi. This enables the the Raspberry Pi to interpret analog voltages that are in turn typically emitted by analog-based sensors to reflect a measure of a physical characteristic such as acceleration, light intensity or temperature. We will start by briefly examining the SPI interface.
