# Makefile to compile code with arduino-cli for defined boards
# on the command line.
#
# Author: Dirk Selbach, [email protected]
# Inspired by: https://github.com/digiampietro/arduino-makefile/tree/master
#
# Build targets:
# 1) Build all defined boards
# make all
# 2) Build ELF for an individual board
# make build/<short-name-of-the-board>/IoTBasic.ino.elf
# e.g. make build/d1_mini/IoTBasic.ino.elf to build ELF for d1_mini board
# 3) Remove build dir for all boards
# make clean
# 4) Remove build dir for an individual board
# TODO
#
# Adding additional boards:
# 1) Get FQBN name of the board you want to add: arduino-cli board listall
# 2) Add the FQBN to the list in FQBN variable below
# 3) Add short name (last part of FQBN) to the list in SBN variable below
