Abstract
A display button and host computer communication device based on 51 singlechips, after pressing the button, the singlechips receive the key signal, it transfers the key signal to the host computer USB port through USB to the serial port chip, thus the host computer can receive the key signal, the host computer can send the key value definition of each button to the singlechips through the USB signal through the host computer USB port, the singlechips store it in EEPROM and keep. The communication between the keys on the display and the host computer side of the computer is realized.
Description
Technical Field
The utility model relates to a computer technology field, concretely relates to display button and host computer communication device based on 51 singlechips.
Background
With the development of electronic technology, people have higher requirements on life quality, and the requirements are more and more embodied and specialized according to the use conditions. For conventional displays, the display panel typically has only MENU buttons for controlling image parameter settings. In a specific field, in order to facilitate the operation of a host on a display end, a plurality of keys need to be added on a display panel, the key values are customized according to requirements, and the keys can be communicated with the host to realize the input of any key value so as to complete specific functions.
Disclosure of Invention
The utility model discloses an overcome not enough of above technique, provide a display button and host computer communication device based on 51 singlechips.
The utility model overcomes the technical scheme that its technical problem adopted is:
a display button and host computer communication device based on 51 singlechip includes:
a single chip microcomputer;
the keys are arranged on the display and connected with the singlechip;
EEPROM, it connects to the one-chip computer;
the USB-to-serial port chip is connected to the single chip microcomputer through a serial communication interface, the USB-to-serial port chip is connected to a USB port of the computer host, and the USB port of the computer host is connected with the single chip microcomputer.
Further, the single chip microcomputer is a C8051 type single chip microcomputer.
Further, the USB to serial port chip is an FT4232HL type USB to serial port chip.
The utility model has the advantages that: after the keys are pressed down, the single chip microcomputer receives the key signals, the key signals are forwarded to the USB port of the computer host through the USB-to-serial port chip, the computer host can receive the key signals, the computer host can send the key value definitions of the keys to the single chip microcomputer through the USB signals and the USB port of the computer host, and the single chip microcomputer stores the key value definitions into the EEPROM for storage. The communication between the keys on the display and the host computer side of the computer is realized.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure, 1, a singlechip 2, an EEPROM 3, a USB-to-serial port chip 4, keys 5 and a USB port of a computer host.
Detailed Description
The present invention will be further explained with reference to fig. 1.
A display button and host computer communication device based on 51 singlechip includes: a single chip microcomputer 1; a plurality of keys 4 arranged on the display, wherein each key 4 is connected with the singlechip 1; an EEPROM 2 connected to the single chip microcomputer 1; USB changes serial port chip 3, and it passes through serial communication interface to be connected in singlechip 1, and USB changes serial port chip 3 connects in computer host computer USB mouth, and computer host computer USB mouth is connected with singlechip 1. When the keys 4 are pressed down, the single chip microcomputer 1 receives the key signals, the key signals are forwarded to the USB port 5 of the computer host through the USB-to-serial port chip 3, the computer host can receive the key signals, the computer host can send the key value definitions of the keys 4 to the single chip microcomputer 1 through the USB signals through the USB port 5 of the computer host, and the single chip microcomputer 1 stores the key value definitions into the EEPROM 2 for storage. The communication between the keys 4 on the display and the computer host is realized.
Further, the single chip microcomputer 1 is a C8051 type single chip microcomputer.
Further, the USB serial-to-serial chip 3 is an FT4232HL USB serial-to-serial chip.
The above description is only the preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, and is not used to limit the protection scope of the present invention.
