Abstract

The invention discloses a rewritable multi-system programmable infrared remote control emission circuit, which comprises two power supply ports, an IR (Infrared Ray) output port, 12 keyboard input ports and a keyboard input/LED (Light Emitting Diode) output port, wherein a programming file is generated by remote control coding software and is programmed into a built-in MTP (Media Transfer Protocol) storage unit.

Description

technical field [0001] The invention relates to a multi-system programmable infrared remote control transmitter circuit for repeated erasing and writing, which belongs to the field of electronics. Background technique [0002] Infrared remote control has a series of advantages such as simple structure, convenient manufacture, low cost, strong anti-interference ability, and high working reliability. It is the preferred remote control method for short-distance remote control, especially indoor remote control. The market is generally based on the design of the infrared remote control transmitter circuit based on the NEC protocol, and the signal collected by the keyboard is encoded with the NEC protocol. And send the signal out through the sending circuit. Many special chips for remote control transmitters use HT6221 to form a transmitting circuit. Generally, DVDs, VCDs, and stereos used in households use this encoding method. When the transmitter button is pressed, a remote c...
