Doxygen <<< landing page has best implementation introduction.
This directory contains the source code for the rusEFI embedded firmware.
TL;DR
make
Embedded firmware is build on top of https://www.chibios.org/ with plain Makefile gcc version 12 (See https://github.com/rusefi/rusefi/blob/master/.github/workflows/hardware-ci.yaml to confirm current GCC version)
Windows development is fully supported with Cygwin, WSL or Linux is recommended due to poor NTFS performance.
