Debug

Files: debug.cpp debug.h Remarks: printf style filtered debug output using usart328p or usart2560. Change the value of g_dbgFilter to reflect which debug messages are displayed.

TWI

Files: i2c.c i2c.h Remarks: Very much a work in progess, particularly the interrupt driven class.

IO

Files: IoDigitalPort328p.cpp IoDigitalPort328p.h Remarks: Uses ASF to configure pins, setup interrupt functions and provide a callback mechanism to clients.

Ringbuffer Files:

RingBuffer.h Remarks: General purpose ring buffer object, used by usart & i2c classes

Timer Files:

Timer2560.cpp
Timer2560.h
Timer328p.cpp
Timer328p.h

Remarks: Interrupt driven timer, with callback mechanism.

USART

Usart2560.cpp
Usart2560.h
Usart328p.cpp
Usart328p.h

Remarks: Interrupt driven usart for data IO or tx/rx pins. Hard coded to a faster baud rate than arduino libs.
