Homebrew for Atmel AVR GCC

This repository contains the Atmel version of the GNU AVR Toolchain as formulae for Homebrew. Atmel does not upstream all their changes to GCC, so this toolchain is the official toolchain, which is different from the open-source version.

Atmel publishes precompiled binaries for Windows and Linux in their website. For OS X there is no website, instead the binaries are hosted together with the sources:

• http://distribute.atmel.no/tools/opensource/Atmel-AVR-GNU-Toolchain/

Two gcc version are provided:

• avr-gcc 4.9.2 in toolchain 3.5.4 (atmel-avr-gcc@35 formula), and
• avr-gcc 5.4.0 in toolchain 3.6.1 (atmel-avr-gcc formula).

Note that avr-gcc 5.4.0 is the very first GCC for AVRs from Atmel to support C++14.

Sidenote: At the time of this writing (November 2017), no binaries for toolchain v3.6.1 for Linux exist. The expected, but non-existant URL would be:
