| # 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 | |
