CSerialPort

CSerialPort is a lightweight cross-platform serial port library based on C++, which can easy to read and write serial port on multiple operating system. Also support C, C#, Java, Python, Node.js, Electron etc.

Design Principles

Cross-platform
Easy to use
Higher efficiency

Platform

CSerialPort was tested on the following platforms

Windows ( x86, x86_64, arm64 )
Linux ( x86, x86_64, arm, arm64/aarch64, mips64el, riscv, s390x, ppc64le )
macOS ( x86_64 )
Raspberry Pi ( armv7l )
FreeBSD ( x86_64 )
...

Todo List

Long-term Goal

1.support windows and linux first
2.add communicating protocol
3.support hot swap - CSerialPortExtend
4.higher efficiency notify module - replace with CSerialPortListener
5.support other language - C, C#, Java, Python, Node.js, Electron etc. - more information bindings
6.sync serial port communication
7.new cross-platform gui serial port tool - CommMaster
8.add introduction and tutorial of CSerialPort - CSerialPort Tutorial
9.serial port monitor hook

Short-term Goal

1.cross-platform OS identify class
2.cross-platform thread class
3.cross-platform lock class
4.cross-platform higher efficiency timer class
5.cross-platform thread pool class
6.Performance test report(Throughput && delay && packet dropout rates)
