The Code uses some Microsoft specific safe C functions like You can also compile the code using GCC or MinGW after a few tweaks. C extension (Eg: MySourceFile.C).Compiler would automatically do the rest. So create a Win32 C++ project and save your source file with a. In Visual Studio,there is no longer an option for creating a C project. Recommended IDE is Visual Studio (Professional or Community Edition).Since we are developing on Windows platform, Contact Us to Enquire about the full Source codes.

Please note that the source codes on the website show only the relevant sections to highlight the process of programming the serial port.

Isolated USB to Serial/RS232/RS485 converter.

One major issue with interfacing real word devices with your PC's is that High voltage spurious transients can couple on to your USB or RS232 or RS485 lines.These high voltage transients can cause severe damage to your computer or its ports. The software is written using C language and communicates with the Serial Port using Win32 API.Īll codes have been tested on a 64bit Windows 10 System.Īll the codes in this tutorial are licensed under MIT License making it eligible to be used for developing proprietary software applications. The tutorial is aimed at Software/Embedded developers who may want to interface real world sensors like DAQ's,USB Relays,USB GPIO boards ,Temperature sensors,Humidity sensors etc to Windows PC. Here i am assuming that you are using a Virtual COM port based any of the numerous IC's available on the market.

This tutorial teaches you to program your Windows PC to communicate with an external peripheral like data acquisition boards, USB GPIO Boards,Relay boards etc through its serial port (Virtual or Real).
