Edit:Shenzhen Koroli Electronic Technology Co., Ltd.   UpDate:2019-11-07

Today, Shenzhen Koroli Electronic Technology will explain some of the knowledge about serial port screens. I hope this article about serial port screens will help you.

Is the serial port screen or the parallel port screen easy to use? Where is the difference?

In terms of wiring pins:

1. Parallel screen requires multiple wire connections

2. The serial screen only needs two wires to complete the communication.

3. In terms of procedures:

4. In the program, the serial screen is already intelligent, with configuration function, the usage is very simple and convenient, the use of serial screen, the program quantity is more than 90% less than the parallel screen, and even many serial screens are not needed. The user's MCU microcontroller can be controlled.

5. Parallel screen, the program is very complicated; relatively speaking

6. Interface: The serial screen has a special interface software, you can directly download the interface and it is very simple.

The difference between man-machine interface and touch screen

In life, we often come into contact with the touch screen, and many people will regard the human-machine interface as a touch screen. In a strict sense, there is a fundamental difference between the two.

“Touch screen” is only the hardware part that may be used in the human-machine interface product. It is an input device that replaces the mouse and keyboard functions and is installed at the front end of the display. The human-machine interface product is a kind of hardware and software. Human-computer interaction device. In the industry, people who have touch input functions are often referred to as "touch screens", but this is unscientific. The touch screen is a popular name for people with "touch-enabled human-machine interface"! The real touch screen is "a transparent glass that can be touched by hand"! It can be used to replace the mouse. Modify the knowledge of the human-machine interface.
