This project is a small UART speed converter using an Atmel ATMega168 microcontroller.
The project was made to convert the UART data from a commercial GPS unit working at 38400bps to the standard 4800 bps of NMEA 0183 data used by Nikon DLSR cameras.

Building requires an avr-gcc toolchain, in the firmware/ directory, to build run:
make
Flashing the firmware on the device requires avrdude and a compatible hardware programmer. Default configuration is stored at the beginning of the Makefile. To program with the default configuration, run:
make load
Fuses can be configured running:
make fuse
