구차니의 잡동사니 모음

다이오드는 허용전류 1A이하의 것이면 상관없습니다.

EXT/USB는 전원을 어떤 것을 쓸지에 대한 선택이므로 AVR STUDIO와는 상관이 없습니다. 하시던대로 사용하시면 되겠습니다.

다이오드를 4148로 임의 교체하여 정상 동작은 확인하였습니다.

It is AVR910 Programmer. used with AVRProg in AVRstudio4. From i test, It does not stably, some time had problem with driver.

No. There is no mechanism for usbasp to work with Studio4. I know nothing about Studio5.

Usbasp is normally 'driven' by avrdude.exe which is a regular commandline program.

For a programmer to 'work' with Studio4 'Connect Programmer', it must appear as if it is a genuine Atmel programmer. e.g. give the correct ID and respond to the protocol.

I can only guess that a 'special_usbasp' would impersonate a AVRISP-2, parse the AVRISP-2 commands and then send the real usbasp commands. Then return any AVRISP-2 type errors. This whole procedure is fraught with problems. You might just as well buy an AVRISP-2 in the first place.

OTOH, if you use an 'external' Makefile with a Studio project, you can do anything you want.

David.

Note that when only using -mmcu=architecture but no -mmcu=MCU type, including the file <avr/io.h> cannot work since it cannot decide which device's definitions to select.
