Summary: Taking the serial port driver of the b0x Chip Based on the ARM7TDMI kernel as an example, this paper analyzes the hierarchy and mechanism of the VxWorks serial port driver, and studies the working principle of the TTY driver and the underlying SCC driver. Combined with the serial port driver of the b0x chip, the design method and precautions of the VxWor

Use Win32 to create a serial communication programAuthor: konchatTranslation: powercpp Download the sample code in this article Introduction:This article describes how to process serial ports in Win32. Serial communication can be achieved through a variety of technologies, such as ActiveX, I/O access and file operations. This article describes how to use

There are two methods in VC ++ for serial communication. One is to use Microsoft Communication Control, an ActiveX control provided by Microsoft. Another method is to directly access the serial port using VC ++. The two methods are described below. I. Microsoft Communications Control Microsoft provides a serial communication control in windows. With this control

The preceding (1) (2) is also a protection method of serial number. At present, many software protection methods still use this serial number protection method. This article will systematically describe this protection method. Most serial number protection requires the user name and serial number, or the machine code,

I. Serial PortAPI 1.Open serial port You can use the createfile function to open the serial port. There are usually two ways to enable it. One is synchronous (nonoverlapped) and the other is asynchronous (overlapped ). Handle hcomm; Hcomm = createfile (gszport, // serial port name Generic_read | generic_write

Abstract: The use of Delphi to develop industrial control system software has become the choice of more and more developers, and serial communication is one of the problems that must be solved in this process. Based on the analysis and comparison of several common serial communication methods, this paper focuses on the use of the Spcomm Control in the Delphi development environment to achieve

An embedded system usually needs to carry out Full-duplex communication with its main control system, for example, a pipelined control system needs to continuously accept the query and control information sent from the master control system, and send the execution result or query result back to the master control system. This paper introduces a simple Java class library which realizes Full-duplex communication through serial port, which simplifies the
