Qiachip 433mhz Remote control + receiver for projection screens or curtains Receiver rf module Rrf remote controller with receiver

Its Qiachip 433mhz  Remote control + receiver for projection screens or curtains Receiver rf module Rrf remote controller with receiver, Clear and code matching: (Clear the code before switching modes) 1. Clear function-After pressing the learning button ""KEY"" 7 times, let go after the LED indicator turns off, wait until the LED indicator flashes 3 times and then turn off, and begin to clear all the remote control code data in the memory, it means that the clear function is completed. 2. Code matching function-press the learning button (jog mode) ""KEY"", the LED indicator lights up to indicate that the microprocessor enters the learning and code matching state, press the matching wireless remote control button, the LED indicator flashes 3 If it turns off after the second time, it means that the code is successfully matched. (The learning button is pressed once to learn to pair the remote control as jog mode; twice to learn to pair the remote control is self-locking mode; press 3 times to learn to pair the remote control as interlock mode;) The wireless remote control switch can store 21 different remote controls , You need to clear the code again before changing the working mode. (This paragraph is one-key code matching, and the program will automatically allocate data bits) 3. Code matching test——After the code matching is successful, when you press the remote control button, the corresponding D0, D1, D2, and D3 output are high level. Explanation of jog mode: Press and hold the remote control button, the corresponding data pin will output high level, release the remote control button, the corresponding data pin will become low level Self-locking mode explanation: Press and hold the remote control button, the corresponding data pin outputs high level, release the remote control button, the corresponding data pin is still high level, press the same button on the remote control again, the corresponding data pin becomes low level (loop) Explanation of interlock mode: Press and hold the remote control button, the corresponding data pin outputs high level, release the remote control button, the corresponding data pin remains high, and then press the same button on the remote control, the corresponding data pin is still high, press another button on the remote control, Last time the corresponding data pin of the remote control changed to a low frequency, the data pin corresponding to the button this time outputs a high frequency (and so on)
