To find out the COM number corresponding to your serial port, etc are given to USB to Serial Converters or PCI serial port extenders. While COM numbers in double digits like COM32, COM54,COM24. COM1 and COM2 usually refer to the hardware serial ports present in the PC (quite rare now) Serial ports are named as COM1, COM2 ,COM3. If your PC does not have any hardware serial ports (RS232 DB9 ports), you can use USB to Serial Converter's like USB2SERIAL.

The arrival of cheap USB to UART chips like FTD FT232RL,TUSB3410,CP2102 have made it quite easy to upgrade the existing software that used to talk over serial to USB protocol.These chips provide a virtual serial port that behaves like a real one but transmits the data through USB. In the 2020's, the old DB9 Serial port is found only on industrial motherboards and old PC's.The once ubiquitous serial port have been completely replaced by the familiar USB standard. The simple protocol and the 3 pin hardware physical lines (RX,TX,GND) made it quite popular among manufacturers who wanted an easy way to connect their devices with a computer. Serial ports are simple 9 pin legacy ports used by the PC to communicate with external peripherals like Printers,Data Acquisition Sytems,Printers etc. Make sure that variables referenced by those functions are also changed. Which are used to get the COM number from the user and create the COM port address string (Eg "\\.\COM9" ).The code will compile on GCC after removing those functions. 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.

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. The UBRRH contains the four most significant bits, and UBRRL contains the 8 least significant bits of the USART baud rate.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). This is a 12 bit register which contains the USART baud rate. ♦ Bit 11:0 - UBRR11:0: USART Baud Rate Register The URSEL must be one when writing the UCSRC. The UCSZ1:0 bits combined with the UCSZ2 bit in UCSRC sets the number of data bits ( Character Size) in a frame the Receiver and Transmitter use. Writing this bit to one enables the USART Transmitter. Writing this bit to one enables the USART Receiver. Well it's dig a little deeper in the init function to see how it is set up.

Well, this looks cool isn't it? Just a one include uart.h and one UART_init(9600) function. UART_Printf ( "Welcome to AVR Serial Programming by ExploreEmbedded \n \r" ) } return ( 0 ) }
