If you’re using macOS you may want use Homebrew to install the needed packages. If you install packages like “avr-libc” and “avr-gcc” the rest of the needed packages (like make) will be installed by dependencies, too. In almost all cases you can get the whole “stuff” easily by using your Linux distributions package manager, like apt-get for Debian and Ubuntu or pacman for Arch Linux. make needs a makefile to know what it’s supposed to do. But it is a very convenient tool, that will do the trivial and boring stuff for you. It can also be configured to use avrdude to flash the compiled binary to the micro-controller. make will run the avr-gcc compiler and other parts from the toolchain, to produce a binary. Make is a build automation tool which, well, automates the build process. In most cases you will use some kind of programmer, that is connected to your computer on one side and to the micro-controller on the other side. BTW: “cross” means, that the compiler itself will run on another architecture than the binary it is compiling.Īvrdude is the tool to actually flash the compiled binary file to a micro-controller. It already contains many functions and header files that are optimised for the target platform.Īvr-gcc is an open source cross-compiler for Atmels AVR micro-controllers and part of the so called toolchain, that will produce a ready-to-use binary that can be flashed to a micro-controller. Avr-libc is the standard library for AVR micro-controllers.
