avr-gcc and avrdude

1. AVR-GCC: The Compiler for AVR Microcontrollers

Note

avr-gcc is a compiler based on the GNU Compiler Collection (GCC) tailored for AVR microcontrollers, such as those made by Microchip. It translates C code into machine code specific to the AVR architecture, enabling the programming of microcontrollers like the ATmega328P and ATtiny series.

2. Setting Up avr-gcc

  1. To begin programming with avr-gcc, ensure the following software is installed:

    Explanation

    1. avr-gcc: The compiler for AVR microcontrollers.
    2. avrdude: A utility for uploading compiled code to the microcontroller.
    3. Makefile (optional): For automating the compilation and uploading process.

2.2 Adding avr-gcc and avrdude for compiling and uploading to your PATH

  1. Add either of the following to your ~/.bashrc file

  • If you are on a university PC then:

    Code

    export PATH=$PATH:"/c/ProgramData/arduino-ide-v2/Local/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin"
export PATH=$PATH:"/c/ProgramData/arduino-ide-v2/Local/Arduino15/packages/arduino/tools/avrdude/8.0.0-arduino1/bin"

  • If you are on a on your own windows PC then:

    Code

    export PATH=$PATH:"/c/users/yourusername/AppData/Local/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin"
export PATH=$PATH:"/c/users/yourusername/AppData/Local/Arduino15/packages/arduino/tools/avrdude/8.0.0-arduino1/bin"
