How to program AVR in Mac OS X? In our college we are using a module developed by IIT Bombay (called FIREBIRD V[ver 5]). It has ATmega2560 and ATmega8 microcontrollers (master and slave) with bootloader.

The staff uses AVR Studio for programming. But since AVR Studio is supported only on Windows (and I have a Mac), I was looking for AVR programming in Mac. I downloaded Crosspack AVR. But I don't know how to proceed after this point. Also I downloaded TextWrangler (because I was told auto-suggestion is not available in TextEdit).

Also I have downloaded the Arduino IDE, and I don't know what is required or how to configure it to program AVR microcontrollers.

I searched on the web and nothing is clear (mostly they all depend on something to do with terminal and the command line).

I don't have Xcode installed in my Mac (I saw a relatively easy tutorial on how to set up Xcode for this purpose) and the file is 4GB. I am trying to work around using Xcode, but if it's the only nice way do let me know!

Pertinent suggestions would be helpful.
If you don't want to use the Terminal and the command line, the Arduino IDE is your best option. Get yourself an AVR programmer (or an Arduino Uno to serve as programmer, with the ArduinoISP sketch uploaded), and code on it.



Then connect your Arduino to your module via SPI. Select the correct processor and port.



You can now upload the sketch:
