315M超再生无线遥控模块驱动
1、315M遥控模块介绍
315MHz遥控是一款超再生无线电通信模块和无线电遥控接收器组成的套件。一般采用2272-M4解码芯片,具有信号稳定、发射距离远、应用简单的特点。

315M模块集成了LC振荡电路,内含放大整形,输出的数据信号被解码后为高电平信号,带四路解码IO输出。
315M超再生无线遥控广泛应用于遥控开关、遥控器、遥控插座、遥控LED、遥控音响、遥控电动门、遥控车库门、遥控伸缩门、遥控卷闸门等等。
接收模块的引脚说明如下:

接收模块的D0~D3引脚对应遥控的ABCD个按键,当遥控按键按下时,对应的按键输出高电平;当遥控按键松开时,对应引脚停止输出。
注意:关于315M遥控模块的具体使用,请根据厂商提供的使用说明。
2、315M遥控接收模块配置
开发环境搭建、系统时钟配置、调试配置及串口配置,请参考:
