This repository contains the code for a cruise control system for a recreational craft. Atmel Studio 7.0 was used to create this AVR-GCC-based project.
- Atmel AVR ATmega328P
- Data bus: 8 Bit
- Clock: 16 MHz external oscillator
- Flash: 32 KBytes ISP
Internal C modules are located in the cruise-control folder.
