摘要
介绍了基于nRF401无线数据传输器件的数传模块的设计与实现,给出了微控制器与nRF401的接口原理图,针对微控制器串行口不足的问题,用软件模拟实现了一个串行口,并得出了51系列单片机波特率自适应功能的定时器初值设定方法,给出了计算公式。
The design of wireless data transmission module based on RF transceiver nRF401 is introduced.The interface circuit between microcontroller and nRF401 is presented,a method which simulates serial port by software is introduced,and successfully solves the scarcity of serial port.The method for setting initial value of timer in MCS-51 single chip computers with band rate self-adapting is discussed, and corresponding setting formulas are given.
