AVR307: Half Duplex UART Using the USI Module

Updated: Jan 20, 2005


(18 pages, updated 10/03)

The Universal Serial Interface (USI) present in AVR devices like the ATtiny26, ATtiny2313, and ATmega169, is a communication module designed for TWI and SPI communication. The USI is however not restricted to these two serial communication standards. It can be used for UART communication as well.
