Data frames should not use non-return to zero codes, let alone long 0 and 1. Use Manchester code or POCSAG code, etc. Interference of microcontroller to Receiver module
RXB10 is generally normal when microcontroller simulates 2262. However, when microcontroller simulates 2272 decoding, it is usually found that remote control distance is shortened a lot. This is because the clock frequency double of microcontroller will cause interference to Receiver Module. 51 series of microcontroller electromagnetic interference is relatively large, 2051 is slightly smaller, PIC series is relatively small, we need to adopt some anti-interference measures to reduce interference. For example, the single chip microcomputer and remote control receiving circuit are respectively powered by two 5-volt power supplies, and the receiving board is powered by a 78L05 separately. The clock area of the single chip microcomputer is far away from the receiver Module
RXB10, so as to reduce the working frequency of the single chip microcomputer and add shielding in the middle.
