5.2. Installing Prerequisites

To program AVRs in macOS, you will need the free avr-gcc compiler, avr-libc, AVRDUDE, and other associated tools.

To obtain these tools, we recommend first installing Homebrew. Then run the following commands to install AVRDUDE and homebrew-avr:

brew install avrdude
xcode-select --install
brew tap osx-cross/avr
brew install avr-gcc
