avrdude Software for programming Atmel AVR microcontroller

AVRDUDE is a program for programming Atmel's AVR CPU's. It can program the Flash and EEPROM, and where supported by the serial programming protocol, it can program fuse and lock bits. AVRDUDE also supplies a direct instruction mode allowing one to issue any programming instruction to the AVR chip regardless of whether AVRDUDE implements that specific feature of a particular chip.
