# Serial Port Programming using Win32 API and C language

<img src="http://xanthium.in/sites/default/files/site-images/serial-prog-win32-api/serial-programming-win32-api-tutorial.jpeg">


This repo contains code for transmitting and receiving characters (Strings) serially between an x86 Windows PC and a Microcontroller (MSP430G2553 on Launchpad).The code is written in C and uses Win32 API calls to control the SerialPort on a Windows machine.

## Online Tutorial

 - [Windows Serial Port Programming Tutorial using Win32 API's and C Language](https://www.xanthium.in/Serial-Port-Programming-using-Win32-API) 

## Details



- The Microcontroller and PC are connected in **null modem configuration** using  3 signals (TX,RX and Ground).

 - The code uses standard Win32 API's to intialize the PC serial port and transmit a character to the microcontroller board.
 - The PC side code is written in **C** using **Win32 API** 
 - and can be compiled using **GCC** or **Microsoft Visual Studio Express**.

- The Code will Work With Standard **RS232 Serial ports** or any **USB to Serial Converter**.

- The Microcontroller side code is written in **Embedded C** and Compiled using **IAR embedded Workbench for MSP430**.

- The Hardware used is MSP430G2553 on Launch pad development board.

## Repo Contents 

- **USB2SERIAL_Read**
  - Contains Code for **Reading data** from the serial port of Windows Machine .
  - A string is transmitted by **MSP430 Microcontroller** which is received by the PC Serialport and then displayed on the Console.

- **USB2SERIAL_Write**
  - Contains Code for **Transmitting data** from the serial port of Windows Machine .
  - A character is **transmitted by the Windows PC** towards the MSP430 Microcontroller.
    The character is received by the MSP430 and an LED on the development board is turned ON to signify data reception.
