# Windows Serial Port Programming Tutorial using C/C++ and Win32 API
- Introduction to Serial Port Programming using Win32 API for Communicating with external devices like Raspberry Pi Pico or Arduino.
- This project demonstrates how to perform **serial port communication** between a **Windows PC** and an **embedded system (like an ATmega microcontroller)** using the **native Win32/Win64 API** in C.
- The program does **not require any external libraries** such as MFC or .NET, and can be compiled using **Visual Studio**.
- Designed for an Software Developer who wants to dabble in Windows System Programming

- [Link to Comprehensive introduction to Serial port programming using Win32 and C](https://www.xanthium.in/serial-port-communication-with-microcontroller-programming-using-win32-win64-native-api)
- Direct access to COM ports using the Win32 API and C language
- Compatible with both 32-bit and 64-bit Windows OS (Windows 7,Windows 8,Windows 10,Windows 11)
- Useful for communication with microcontrollers, Arduino, sensors, etc.
- Learn to Read and Write into Windows Serial Port using Win32 API and C/C++
- Learn to set Read Timeouts in Windows Serial port Programming
- We teach how to read from serial port using polling strategy and ReadFile() function
- Learn to build event driven serial communication system using the WaitCommEvent()
- Build a Bi-Directional Serial Communication link between Windows PC and Arduino using Win32 API in C/C++
## Prerequisites
- Windows (Win10/11 32/64-bit)
- Visual Studio 2017/2019/2022
- Basic knowledge of **C** and serial communication
- Arduino or other Microcontroller Board
## Hardware Setup for Serial Port Communication with Microcontroller using Win32 API
You will need:
- A USB-to-Serial converter or real serial port (e.g., COM1)
- A microcontroller or loopback device for testing
- (Optional) Virtual Serial Port Emulator if no hardware is available
-
