| Abstract: | Wireless digital signal transmission has been widely used in electronic product due to its powerful anti-jamming capability if it is mated with coding and decoding function, it can handle multi-survey better in engineering. This paper introduces a kind of MCU control circuit using coding and decoding chip PT2262/ 2272, and analyzes the time sequence of transmission data in circuit construction. In order to correctly set the writing of software, speed up the program compiling speed; this paper also combines the circuit design about wireless and receiving module with problems met in practice. The important technology points which should pay close attention to are also pointed out. |
