Interfacing an SPI ADC (MCP3008) chip to the Raspberry Pi using C++ (spidev)

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 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 …

ADC Circuit: Raspberry Pi Analog Input Circuit on Breadboard

This project shows how to construct a simple MCP3002 Analog-to-Digital Converter (ADC) circuit with a test potentiometer input. It shows how to wire the SPI pins for successful data communication between the ADC and the Raspberry Pi. Breadboard Build A breadboard, or “solderless breadboard”, is a tool, which allows engineers to rapidly prototype their circuit …
