Embodiment Construction

[0036] see figure 1 , an infrared remote control for sending display codes for LED dot matrix displays, which includes:

[0037] 1) Microprocessor: It can be realized by ordinary single-chip microcomputer, such as 51 series single-chip microcomputer and PIC series single-chip microcomputer.

[0038] 2) Serial port: connected to the serial receiving and sending pins of the microprocessor, used to connect with the serial port of a PC or mobile device, and receive the dot matrix display code of characters or graphics.

[0039] 3) Non-volatile storage device: connected to the microprocessor through the main control synchronous serial port. In this embodiment, the non-volatile storage device is EEPROM, which is used to store the dot matrix display code of characters or graphics received through the serial port. .

[0040] 4) Button 1: connected to the input pin of the microprocessor, used to send control commands to the microprocessor, start the infrared transmitter, and emit the...

Abstract

The invention provides an infrared remote controller for sending a display code to an LED dot matrix display screen and a control method thereof. The infrared remote controller comprises (1) a microprocessor; (2) a serial port which is connected with serial receiving and sending pins of the microprocessor, and used for receiving the dot matrix display code; (3) a nonvolatile storage device which is connected with the main control synchronous serial port of the microprocessor, and used for storing the dot matrix display code received by the remote controller; (4) a button (1) which is connected with an input pin of the microprocessor, and used for sending an infrared emitter starting signal to the microprocessor; (5) an infrared emitter used for emitting the stored dot matrix display code of the character or graphic; (6) a digital display component (2) used for displaying the serial number of the information currently emitted by the infrared emitter in the nonvolatile storage device; and (7) a remote controller power supply. The invention has the advantages of refreshing the display content on the LED dot matrix display screen more quickly and conveniently, and also providing more abundant display content for the LED dot matrix display screen.

Description

technical field [0001] The invention relates to an infrared remote controller and a method thereof, in particular to an infrared remote controller and a control method for sending display codes for an LED dot matrix display screen. Background technique [0002] At present, the application range of LED dot matrix display screens is getting wider and wider, and the displayed content is becoming more and more diverse, such as Chinese characters, English characters, digital characters or graphics. However, the information displayed on the LED dot matrix display is often not static and needs to be updated in due course. The current method of updating the display content of the LED dot matrix display is usually to first connect the serial port of the PC to the serial port of the display screen through a serial port cable, and then use the PC to send new display content to the display screen. A big disadvantage of this method is that many LED dot-matrix displays are fixed in a cer...
