#
# Builds custom upload command
# 1) Run platformio as a subprocess to find a COM port
# 2) Build the upload command
# 3) Exit and let upload tool do the work
#
# This script runs between completion of the library/dependencies installation and compilation.
#
# Will continue on if a COM port isn't found so that the compilation can be done.
