GdSerial: Bringing PySerial-like Functionality to Godot 4

Introduction

When working on interactive applications that need to communicate with hardware devices like Arduino boards, sensors, or custom electronics, developers often face the challenge of integrating serial communication into their projects. While Python developers have the excellent PySerial library, Godot 4 developers have been lacking a comprehensive, easy-to-use solution.

GdSerial is a Rust-based extension that brings PySerial-like functionality directly to Godot 4, enabling seamless serial communication for games, applications, and research tools.

Key Features

Usage Example

Interfacing with an Arduino board is now as simple as a few lines of GDScript:

extends Node

var serial: GdSerial

func _ready():
    serial = GdSerial.new()
    serial.set_port("COM3")
    serial.set_baud_rate(115200)
    
    if serial.open():
        serial.writeline("GET_DATA")
        var response = serial.readline()
        print("Data: ", response)
        serial.close()

Conclusion

GdSerial bridges the gap between Godot's powerful application development capabilities and the world of hardware interaction. Whether you're building research tools, educational applications, or interactive installations, it provides a robust foundation for hardware integration.
