BBC:MICROBIT v1
===============
Quickstart
----------
Installing PlatformIO (once per box)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
python3 -m venv --system-site-packages venv-platformio
./venv-platformio/bin/python3 -m pip install -U platformio
Preparing /etc/fstab for uploading (once per box)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
sudo mkdir -p /media/microbit
echo 'LABEL="MICROBIT" /media/microbit auto noauto,user 0 0' | sudo tee -a /etc/fstab
sudo systemctl daemon-reload
Compiling
^^^^^^^^^
./venv-platformio/bin/pio run
Uploading
^^^^^^^^^
mount /media/microbit; cp .pio/build/bbcmicrobit-maqueen/firmware.hex /media/microbit; umount /media/microbit
Random notes
------------
- what works:
- Arduino :(
- adafruit's microbit library
- obsolete maqueen library
- newping
- platformio
- bleak
- what does not work:
- platformio on raspberry pi: insist on embedded srecord, which is compiled
for eabihf and I couldn't get it to load
- makecode + bluetooth + maqueen: out of mem (020)
- dal/codal, yotta, mbed etc.: I coudn't get it to work, and I'm appalled
by the constant nagging by mbed to sign in
also plaformio doesn't support mbed for microbit (only arduino and zephyr)
- didn't try zephyr
- didn't try micropython, because LU docs say it won't have bluetooth
- bluezero: confuses tx and rx for some reason (works with makecode,
probably tested only against that one)
- didn't try gattlib

Won't work with bluetooth. Maybe I can get it to work on ESP32? Would
require another robot.
