Interfacing Microchip's MCP41XXX/42XXX Digital Potentiometers to a PICmicro Microcontroller

From Microchip Technology, Inc.
 

 
The MCP41XXX and MCP42XXX family of digital potentiometers communicate using a standard 3-wire SPI compatible interface. This application note will discuss communications between these devices and a PIC16F876 microcontroller. The code supplied with this application note will include both absolute and relocatable assembly code, written for both hardware SPI and firmware SPI implementations.
