define HELP_MAKEFILE
Usage:  make <target>   where <target> can be:

  build           Use platformio to build the firmware
  upload          Use platformio to upload to the board (rebuild if necessary)
  monitor         Use platformio serial monitor (auto-detect port)

  firmware        Perform all three steps in a row.
