TWI code for master and slave mode of I2C.
This code is written in C for avr-gcc.
This code is an interrupt driven implementation of the TWI.
A demo program is included (with AVR studio 4 project files).
The demo program was compiled for an Atmega324P and should work
with other dual UART AVR's without needing to edit the demo c file.
