1. API description In Win32 API, the serial port uses the file access method, and its operation API is basically the same as the file operation API. Open serial port In Win32, the API function used to open the serial port is createfile, and its prototype is: Handle createfile (Lptstr lpfilename, // name of the serial p

Many serial peripherals are used in the automotive terminal project, such as DVD movement, GPS, Bluetooth, radar, and tire pressure monitoring. The main CPU (TCC89XX) and small MCU (STM32) through serial communication. For a moment, the serial port is a little too slow to use. You can only use the debug serial port for

Do not often contact computer friends may be a lot of small computer knowledge do not understand, today's editor in the QQ group of computer enthusiasts have found a friend asked a relatively simple, but the novice friends generally do not pay attention to the problem: what is a serial disk, what is the same port hard drive. Whichever speed is faster and so on. The author found that a lot of friends do not understand or know the incomplete, editing he

What I want to do is a serial port tool similar to a Super Terminal for AT command applications. The option card interface sends at commands to communicate with the data card, facilitating R D personnel to read and write data cards and testers to test, improve work efficiency.Start with two images:When receiving this task, we must first analyze the two main parts of the software. What are the main technical difficulties? The software includes two par

Under Win32, you can use two kinds of programming to implement serial communication, one is to use ActiveX control, this method is simple, but less flexible. The second is to call the Windows API function, this method can clearly grasp the mechanism of serial communication, and free and flexible. The following is a description of the API serial communication cont

In computer systems, there are two main types of data communication: one is serial communication, where the binary bit of each character is arranged by bit for transmission, which is slow, but the transmission distance is far away. Both the mouse port and USB port belong to the serial port. The other is parallel communication. The binary bit of each character uses multiple data lines for simultaneous transm

I recently summarized three methods of reading and writing through the serial port (COM:The 1st method is to use a serial control launched by Microsoft in. net2.0. the SerialPort class must be. net2.0.The 2nd method is to use APIs to write serial communication. Although it is difficult, you can easily implement the various functions you want.The first method is t
