A simple library for asynchronous serial communication

EasyCom

EasyCom is a Python library for asynchronous serial communication with USB UART devices. It supports hardware like Arduino, ESP32, Raspberry Pi Pico, Teensy, and others. EasyCom offers non-blocking communication with an easy-to-use API and allows you to dynamically register new devices at runtime.

Features

• Asynchronous Communication using threads for non-blocking operations.
• Pre-configured and Dynamically Registered Devices support.
• Automatic Port Detection via PID/VID pairs.
• Thread-safe Writes using queue-based management.
• Customizable Data Handlers for processing incoming data.

Installation

Install EasyCom and its dependencies via pip:

pip install easycom pyserial

---

Usage

Example: Arduino Communication

This example demonstrates sending and receiving data using an Arduino device with a callback function:

from easycom.devices import Arduino

# Callback function to handle received data
def handle_data(data):
    print(f"Received: {data}")

# Initialize the Arduino with the callback function
arduino = Arduino(port="/dev/ttyUSB0", data_handler=handle_data)

# Send data to the Arduino
arduino.write(b"Hello, Arduino!")

# Keep the program running to receive data
input("Press Enter to disconnect...")

# Disconnect the Arduino
arduino.disconnect()

---

Registering a New Device at Runtime

You can dynamically register a new device using the register_device function:

from easycom.devices import register_device

# Register a new device class named "MyDevice"
MyDevice = register_device(
    name="MyDevice",
    pidvids=["1234:5678"],
    default_baudrate=115200,
    default_timeout=3
)

# Use the registered device
device = MyDevice(port="/dev/ttyUSB0")
device.write(b"Hello, MyDevice!")
device.disconnect()
