PySerial

PySerial is a Python library that provides a simple and robust interface for serial communication. It is designed to work with various operating systems, including Windows, macOS, and Linux. The library supports both synchronous and asynchronous communication, making it suitable for a wide range of applications, from simple data logging to complex real-time systems.

PySerial is open-source and is available under the BSD license, which allows for both personal and commercial use. The library is maintained by Chris Liechti and is actively developed on GitHub, where users can contribute to its development and report issues.

The library provides a straightforward API for opening and configuring serial ports, sending and receiving data, and handling errors. It supports various serial port settings, such as baud rate, data bits, parity, stop bits, and flow control. PySerial also includes features for handling timeouts and buffering, which are essential for reliable communication.

One of the key features of PySerial is its support for non-blocking I/O, which allows for efficient handling of multiple serial ports in a single application. This is particularly useful in applications that require real-time processing of data from multiple sources.

PySerial is widely used in various fields, including robotics, embedded systems, and scientific research. Its simplicity and robustness make it a popular choice for developers who need to integrate serial communication into their Python applications. The library is well-documented, with extensive examples and tutorials available to help users get started.
