USBasp – USB programmer for Atmel AVR controllers

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.

Features

  • Works under multiple platforms. Linux, Mac OS X and Windows are tested.
  • No special controllers or smd components are needed.
  • Programming speed is up to 5kBytes/sec.
  • SCK option to support targets with low clock speed (< 1,5MHz).
  • Planned: serial interface to target (e.g. for debugging).
