Decoding method of infrared remote control software

The invention provides a decoding method of infrared remote control software, comprising the following steps of: connecting the output end of an infrared remote control receiver to the interrupt input pin of an embedded microprocessor; starting a preset decoding program via the embedded microprocessor when the remote control encoding pulse signal received by the infrared remote control receiver passes through the interrupt input pin of the embedded microprocessor; testing the logic level and the pulse width of each pulse signal in each group of remote control encoding pulse signals, and decoding each group of remote control encoding pulse signals by means of a preset decoding rule to obtain the corresponding digital signals; searching characteristic values matched with the digital signals from the plurality of preset characteristic values to obtain the remote control command corresponding to the matched characteristic values; and executing the remote control command. The method adopts the software decoding te
