arduino rs232 interface

Description of RS232/RS485/rs422 Interface Converter The DMUs series converter is a standard RS232/RS485/rs422 converter that completes the electrical conversion between the serial RS232 and RS485/rs422, and can extend the maximum communication distance to 1200 meters (4000 feet ). DMUs adopt the basic three-line s

This paper describes the design of the controller based on RS232 interface. It uses a single-chip microcomputer to control the interface chip nat914, and uses SCPI statements in the Super Terminal of the serial communication tool that comes with the winelows operating system, the communication and program-controlled operation between the computer and the Kaplan i

CAN bus/RS232 interface design [Date:] Source: foreign electronic components by Zhao Jie, Liu weijing, Sun Huijia, Li Nan [Font:Large Medium Small] 　 1 IntroductionCAN is called "Controller Area Network", that is, Controller LAN, is an international standard, high-price Field Bus, plays an important role in the field of automatic control. CAN is a multi-master serial communication bus w

Both VGA and DVI are video transmission lines. The former is the traditional analog transmission, the latter species is more, there is only the transmission of digital or analog or digital mode is transmitted, in short, the latter video signal transmission quality is higher than the former, and transmission speed faster. Many displays on the market now use the DVI interface (including HDMI, HDTV, and DisplayPort, etc.)Interfaces are very easy to diffe

Analogwrite (pin, value) First follow the connection number Circuit This time, we will use Arduino and a set of three-color lamps (red, yellow, and green) to Apply PWM. First, let's take a look at the Arduino board. There are six PWM interfaces in total, they are digital interfaces 3, 5, 6, 9, 10, and 11. For convenience, we use the continuous PWM interfaces 9, 10, and 11. During program writing, we wi
