the aim of this module is to send data from/to GODOT <-> Arduino (tested and working on linux platform)

in this demo :

• at the top between < >, data coming from arduino
• at the bottom, integer sent to arduino and controling the intensity of the red LED.

in this project, the arduino nano is wired with MPU9250/MPU650 module SDA --> A4 and SCL --> A5

a led is also wired to D3 in order to be controled from godot

to be copied in Godot module folder (godot-3.x.y-stable/modules/arduino_f/)

in file : comments the line (if not, it is a define for using this module in the main file -> see main.cpp)

// #define TEST_arduino_f_module_in_main

and build again with scons in the main directory /godot-3.x.y-stable (x11 for linux)

scons platform='x11' -j4

(to use 4 threads)

code could be used as is with the main.cpp go to the Godot module folder and :

scons -j4

Godot code to be opened in Godot

open doxyfile with doxygen --> run doxygen --> show HTML output --> enjoy browsing in this beautiful documentation ;)

• add crc check for the strings transmitted from and to Godot

• add the possibility to choose in Godot directly the speed of sending message (for the moment every 10 ms)

• add a second loop to have two channels of sending message in different speed ; for example, fast message every 10 ms and low message every 1000 ms

• add connectivity via WiFi, Bluetooth
