Embedded – Microcontroller – STM32 Driving Digital Potentiometer (MCP41010)
The MCP41010 is a single-channel digital potentiometer produced by Microchip, supporting SPI interface, with a resistance value of 10kΩ and a resolution of 8 bits (0-255 wiper positions). Below is the complete implementation scheme for driving the MCP41010 via SPI with STM32, as shown in the circuit diagram below. STM32 Pin MCP41010 Pin Function Description … Read more
