This repo contains the firmware replacement pbLua that enables a Lua runtime on the Lego Mindstorms NXT robots. You can simply write code in any text editor and transfer it to the brick via a serial connection (USB/Bluetooth), for instance by using screen or minicom. Compilation and execution then takes place on the NXT itself. Additional scripts which are helpful for eased handling and transmission of scripts can be found in the pbLuaConnect repository.

The project was developed by Ralph Hempel and originally provided at his website. Due to downtime of this page the most recent stable package is mirrored here for now. No license is provided as all rights belong to their respective owners. Please contact Mr. Hempel for any enquiries.
