AVR 이란

AVR은 중앙처리장치와 소용량 플래시메모리가 하나의 IC에 집적되어 있다. AVR 하버드구조(Harvard architecture)의 변형 형태로 프로그램과 데이터 메모리가 분리된 형태이다. 특수 명령어로 프로그램 데이터를 데이터 영역으로 읽을 수 있다. Atmel에서 탄생한 AVR은 2016년 Microchip에 인수 되면서, 새로운 전기를 맞았다.

AVR의 종류

아트멜 AVR은 AVR UC3, AVR XMEGA, megaAVR, tinyAVR 시리즈 등이 있으며 그 중, ATmega128이 교육용으로 가장 흔하게 쓰인다.

ISP

6핀 또는 10핀 ISP 연결 커넥터 ISP(in-system programming) 프로그램 전송 방식은 기능적으로 SPI 방법에 Reset 선을 추가한 것이다. PCB에 납땜 상태에서 프로그램 코드를 전송할 수 있다. AVR에서 가장 일반적인 방법이다.Atmel AVR ISP mkII 장치는 USB에 연결하고 Atmel의 ISP 프로그램에 의해 동작한다.
AVRDUDE (AVR Downloader/UploaDEr)는 Linux, FreeBSD, 윈도, OS X에서 실행되며 다양한 하드웨어(Atmel AVR ISP mkII, Atmel JTAG ICE)로 프로그래밍을 할 수 있다.
AVR의 대표적 개발환경인 Atmel Studio는 현재 7.0 버전까지 나와있으며, Microsoft의 Visual Studio를 바탕으로 만들어져 UI가 매우 유사하다.
AVRISP MKII와 같은 툴 없이 아두이노를 ISP 툴로 만들어 사용할 수 있다.
