Digital to Analog Converters (DAC’s)
This attached tutorial is a follow-on to my earlier Digital Potentiometers 101 tutorial which I prepared in December 2009.
For the Digital Potentiometer tutorial, see this thread:

This tutorial covers the R-2R resistor network concept and the Microchip MCP4821/4822 with SPI interface. The code was test on the MCP4822.
forum member Janne has a further code snippet for the MCP4921/4922 at:

For most intents and purposes, the MCP4821/4822 and the MCP4921/4922 are identical from a program control viewpoint
