Abstract
】
This design is aimed at the application requirements of the competition responder
,
so as to research and design a new type of multi-channel wireless responder controlled by single chip microcomputer. The multi-channel wireless responder designed this time is programmed in C language. By using the STC89C52 microcontroller as the main controller
,
the independent key module is used to connect to the GPIO port of the STC89C52 microcontroller to transmit the level signal. The refere
