How to call my native C++ code from Lua.

Start with creating a project from the template “Native Extension” when starting the editor.
You can read more in the manual (the readme in the project links to it as well):

Is it possible to send messages to the Pico from Defold and how?

If you have the Raspberry Pi Pico “W” (wifi) then you can get/send messages from WiFi network by using http. Using C for usb connection might be more challenging (but not impossible).

Oh! OK, then I don’t recommend him to mess with C/C++ if he is not a C/C++ guru

You can get messages from the buttons themselves to the pico (but you can’t send messages from defold to the Pico). So, you could program the pico so that LEDs turn on and off according to button presses (if your LEDs work with 3.3v, which is what the pico outputs from GP). It would involve putting these lines of code in somewhere:

Just to be clear by the way - I’ve always used this method. It’s very easy. It might not fit your set up if your game is very complicated, but in the three projects I’ve done, it’s always worked.

Here, for example

I’ve created a very simple reflex trainer game. The lights are controlled by a modified raspberry pi which also sends keypresses to defold just like a USB keyboard. Sorry for the messy desk.
