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.
In the world of electronics, microcontrollers play a significant role in controlling various devices and systems. They are small, integrated circuits that contain a processor, memory, and peripherals, and are capable of executing programmed instructions. One common application of microcontrollers is in wireless communication systems, where they are used to control receiver modules.
However, it is important to be aware of the potential interference that microcontrollers can cause to
RXB10 receiver modules. Interference refers to the disturbance or disruption of the proper functioning of a device or system caused by external factors. In this case, the interference is caused by the microcontroller itself.
There are several ways in which a microcontroller can interfere with a receiver module. One common form of interference is electromagnetic interference (EMI). EMI occurs when the electrical signals generated by the microcontroller interfere with the signals being received by
RXB10 receiver module. This can result in a loss of data or a decrease in the quality of the received signal.
Another form of interference is radio frequency interference (RFI). RFI occurs when the microcontroller emits radio frequency signals that interfere with the radio frequency signals being received by the receiver module. This can lead to a loss of signal strength or even complete signal loss.
To minimize interference from microcontrollers to receiver modules, several measures can be taken. One approach is to use shielding techniques. Shielding involves enclosing the microcontroller and the receiver module in a metallic or conductive material that acts as a barrier, preventing the interference signals from reaching the receiver module. This can be particularly effective in reducing EMI and RFI.
