利用编解码芯片的无线收发电路

Wireless Transmitting and Receiver Circuit Using Coding and Decoding Chip

无线数字信号传输由于抗干扰性强,在电子产品中得到广泛应用,若配以编码和解码功能,便可以更好地处理工程中经常遇到的多点测量需要区分不同探点的问题。介绍一种利用编解码芯片PT2262/2272的单片机控制电路,并分析了电路构建中所传输数据时序的处理过程,以利于编制软件时进行正确的设置,加快程序的编写速度;结合无线收发模块F05C/J04E的使用及实际电路设计中遇到的问题,给出了设计中需要重点关注的技术环节和电路调试时需要注意的事项。

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.
