One reason for me to install windows on my Macbook Air is do something with AVR. After long search on Internet. I found the solution to move this thing back to MacOS.
1. CrossPack – A development environment for Atmel AVR (http://www.obdev.at/products/crosspack/index.html)
With this CrossPack you can use command line to compile your code.
How to program hex file to your AVR
avrdude -p m328p -c avrisp2 -P /dev/cu.usbmodem00001201 -U flash:w:3pi-serial-slave.hex
But you also able to use GUI tools like ‘eclipse’. By install this following program.
1. Eclipse IDE for C/C++ Developer (http://www.eclipse.org/downloads/)
2. Open Eclipse program and goto “Help -> install new software” and type “http://avr-eclipse.sourceforge.net/updatesite”
