si4432发送模式的配置问题
我用430和si4432做的点对点无线通信，为什么我的程序跑到接收数据模式的时候就跑飞了。下面是我的代码希望高手多多指教。我做了个发送模式的，可以正常发送。但是就是进入接收模式的时候程序跑飞了，voidSI4432_Init(void)

}
就是在使能接收连接的时候跑飞了。我担心是不是初始化出了问题。请各位大侠帮帮忙，小弟不胜感激。 问题解决了，就是寄存器初始化出了问题。 linqixing 发表于 2013-5-21 01:12 static/image/common/back.gif

是那个寄存器初始化的问题呢，能具体讲一下吗，谢谢！ 使用分集天线功能，信号更好，直接软件控制好就行了吗，需不需要软件控制的。
