Serial Communication Overview There are many kinds of serial communication protocols, such as rs232,rs485,rs422, even the popular USB is serial communication protocol. And the applicat

operating system and window operating system. The main modules of serial communication program design are visual c++6 respectively. 0 programming environment and Unux development. In this paper, the similarities and differences of serial communication programs in two programming environments and their comparisons are

, can solve even a minor problem for your project, it is enough.Although my introduction to this series of things is not a web framework, nor any open source server, but I believe that as a programmer, what kind of problems will be encountered. Sometimes the more simple the problem is, the less it is, the harder it is to find the guy. As long as you are not dealing with "architecture", "widget" or "frame" all day, believe what I say you will use.1 Introduction to

Basic concepts of Serial Communication 1. What is a serial port?2, what is RS-232?3, What Is RS-422?4, What Is RS-485?5. What is a handshake?1. What is a serial port?The serial port is a protocol used to communicate with a very general device on a computer (do not confuse it

The basic data communication methods can be divided into parallel communication and serial communication:Parallel Communication: it refers to the simultaneous transmission of one piece of data using multiple data transmission lines. It features high transmission speed and is suitable for short-distance

Parallel and serial basic communication mode1. Parallel communication modeIt is usually the data bytes that are transmitted at the same time with multiple data lines.The parallel communication control is simple, the transmission speed is fast, because the transmission line is many, the long-distance transmission time h

RS-232 serial port, serial port by bit to send and receive bytes. Although it is slower than byte parallel communication, the serial port can use one line to send data while the other line to receive data. Typically, the serial port is used for ASCII character transmission.

protocol, as long as the single-chip microcomputer in accordance with the Modbus protocol to send and receive data, you can communicate. The touch screen and MCU are connected directly with RS-232 or RS-485 standard interface, and the transfer rate is set to 9600bps. Figure 1 is the circuit diagram of the system.
