I believe the question “how to communicate to Pico from Defold” better to split into a few smaller questions:
- how to send a data/signal to Pico? It’s a microcontroller probably similar to Arduino, so it should be able to send and receive data via USB. Just a first article after quick search. How to send data to a Raspberry Pi Pico via USB | smittytone messes with micros
There might be YouTube videos about it. - How to run C++ (or other) code inside Defold? I assume that there are examples in C++ how to communicate with Pico.
- How to call my native C++ code from Lua.
