NRF24L01检测是否存在，成功了。但是发不出数据。。
测试是IRQ引脚没有反应。
代码如下：
mian.c代码：
SysInit(); //ϵͳ³õʼ»¯º¯Êý
UsartInit();//´®¿Ú³õʼ»¯º¯Êý
LCD_init(); //LCD5110³õʼ»¯º¯Êý

LCD_clear();
//³õʼ½çÃæ

SendString("Hello!"); //´®¿Ú´òÓ¡Êý¾Ý
SendString("\r\n");
SendString("This is NRF24L01 Test..");
SendString("\r\n");

while(1)//¼ì²âNRF24L01ÊÇ·ñÔÚÏß

}

break;
}
}

知道什么是神吗？其实神本来也是人，只不过神做了人做不到的事情 所以才成了神。 （头文字D, 杜汶泽）
