Arduino Lua Interpreter

A basic example of an embedded Lua interpreter within the Arduino framework

Overview

This project demonstrates how to integrate a Lua interpreter with Arduino, allowing you to run Lua scripts on Arduino-compatible hardware. This can be useful for adding scripting capabilities to your embedded projects.
The project was built on a Raspberry Pi Pico board, but can be easily edited for other boards thanks to the PlatformIO IDE

How to build PlatformIO based project

1. Install PlatformIO Core
2. Сlone this repository
3. Run these commands:

# Build project
$ pio run

# Upload project
$ pio run --target upload

# Clean build files
$ pio run --target clean

Usage example (Fibonacci sequence and custom function)

$ pyserial-miniterm /dev/ttyACM0
--- Miniterm on /dev/ttyACM0  9600,8,N,1 ---
--- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---
> function fib(n) if n <= 0 then return 0 elseif n == 1 then return 1 else local a, b = 0, 1; for i = 2, n do a, b = b, a + b; print(b) end end end
> fib(22)
