RS-232 RS-232-C is a serial physical interface standard established by the Electronic Industry Association (EIA) in the United States. RS is the abbreviation for “Recommended Standard”, 232 is the identifier number, and C indicates the number of revisions. Its full name is “Serial Binary Data Exchange Interface Technology Standard between Data Terminal Equipment (DTE) and … Read more
Click the blue text to followServo and Motion Control Introduction to RS-232, RS-422, and RS-485 Overview of RS232 The RS-232 interface conforms to the interface standard for serial data communication established by the Electronic Industries Alliance (EIA), with the full original designation being EIA-RS-232 (abbreviated as 232 or RS232). It is widely used for connecting … Read more
Open the GenericApp project, and in the Workspace we can see these options Coordinator: Coordinator, RouterEB: Router, EndDevice: Terminal node. Choose different options, and after compilation, different firmware will be generated. Now let’s write a coordinator first. 1. Using the Coordinator Serial Functionality Add our serial initialization function in the GenericApp.c file within the GenericApp_Init … Read more
Course Details: The “Practical Tutorial on RS-485 Communication Module” is designed and planned by a team of professional electronic engineers from Changxue Electronics, and is recorded exclusively. This course mainly introduces the process, methods, techniques, and design concepts of developing the 51 microcontroller module through the form of module instantiation, focusing on the system design … Read more
To enable communication between devices, there needs to be a bridge connecting the two, which consists of the transmission path and communication protocol. The earliest interface used for device communication was RS232. However, as technology developed, RS232 began to show some limitations, which led to the emergence of new interface standards, one of which is … Read more
The bus, known in English as “BUS”, is very much like a public bus. The route of a public bus is fixed, and anyone can take the bus to any stop along its route. If we compare people to electronic signals, this is the true meaning behind why it is called “BUS” in English instead … Read more
We see that this touchscreen serial interface has RS485 as well as RS232. Here, we will briefly explain and distinguish between the serial interfaces RS485/RS232/RS422. RS232:Is a three-wire communication (1 transmitting wire, 1 receiving wire, and 1 common wire which is the reference ground GND). RS422:Is a four-wire communication (1 for transmitting +, 1 for … Read more

Hello everyone, good evening~ Today, I will introduce how many communication methods are available for Siemens PLC. Siemens PLC is a brand that many people frequently use, so today I will share the various ways to achieve communication with Siemens PLC in upper computer development. Here, we can explain from three aspects: serial communication, Ethernet … Read more
From the relevant information about the Raspberry Pi, we can see that there are two serial ports available: one is the hardware serial port (/dev/ttyAMA0), and the other is the mini serial port (/dev/ttyS0). The hardware serial port has a separate baud rate clock source, providing better performance and stability; the mini serial port has … Read more
