An embedded operating system toolkit for LEGO MINDSTORMS NXT.
This project is forked from nxos, developed by David Anderson and others.
This fork updates it to make it work on today's computers.
Requirements
- GNU ARM Embedded Toolchain v10-2020-q4 or similar. This repository assumes
that
arm-none-eabi-gccis on your path. - Python 3.8 or newer.
- Poetry v1.x.
- Pybricksdev udev rules
- See this guide for tips, tricks and useful references.
Building
poetry install
poetry shell
cd nxos
scons appkernels=examples/sound
This builds sound_samba.bin which can run from RAM, and sound_rom.bin which can be installed on flash.
Deploying
First, put the NXT in update (SAMBA) mode:
- Press and hold the small button in the LEGO Technic pin hole under the USB port for 5 seconds.
- Turn the hub on. You will hear a clicking sound.
To run a firmware from RAM and then go back to update mode:
pynxt fwexec systems/examples/sound/sound_samba.bin
To install it on the brick permanently:
pynxt fwflash systems/examples/sound/sound_rom.bin
