AVR320: Software SPI Master
Updated: Feb 24, 2005
The Synchronous Peripheral Interface (SPI) is gaining rapidly in popularity, allowing faster communication than I2C. For the smaller AVR Microcontrollers, which do not have hardware SPI, this Application Note describes a set of low-level routines for software implementation. These can be used as the basis for communicating with Atmel's 25xxx family of Serial EEPROM memories, as well as a host for other peripheral ICs such as display drivers.
