USBasp - 

USB programmer for Atmel AVR controllers


Features
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.

  • 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).

======================


자작 PCB로 제작

==> 오류 : Unknown USB device !!

==> Atmega8을 사용하라고 되어있는데 ATMEGA8A 사용했더니 오류임

==> 결국 atmega8-16을 사용했더니 인식됨


주의 : 새로산 AVR 인 경우 내부 클럭1MHz 로 설정되어 있으므로

        SLOW SCK 점퍼를 ON 해야 인식된다
