单片机控制NRF24L01发送，STM32控制接收。。。

我用单片机做发送程序，检测到了发送完成标志位，但是在原子哥的MINISTM32板子上也没有接收到数据。。。<br />
<br />
<br />

主函数while（1）里面的程序段：
<div style="background-color:#E8E8E8;">
[mw_shl_code=c,true] NRFSetTxMode(TxDate); //·???
while(CheckACK()); //?ì????·?·????ê±?

[/mw_shl_code]
</div>
<div style="background-color:#E8E8E8;">
[mw_shl_code=c,true]//发送程序：[/mw_shl_code]
[mw_shl_code=c,true]/*****************NRF?è????·?????????·???????******************************/
void NRFSetTxMode(uchar *TxDate)
{//·???????
CE=0;
   NRFWriteTxDate(W_REGISTER+TX_ADDR,TxAddr,TX_ADDR_WITDH);//???????÷????+???????·????????+???????·+???·?í??
NRFWriteTxDate(W_REGISTER+RX_ADDR_P0,TxAddr,TX_ADDR_WITDH);//?????????????è±????????¨??0???·??·??????·?à??
NRFWriteTxDate(W_TX_PAYLOAD,TxDate,TX_DATA_WITDH);//????????
/******?????????????÷????**************/
    NRFWriteReg(W_REGISTER+EN_AA,0x00);    // ?????????¨??0×???????
    NRFWriteReg(W_REGISTER+EN_RXADDR,0x01); // ?????????¨??0
    NRFWriteReg(W_REGISTER+SETUP_RETR,0x0a);  // ×?????·????±????250us+86us??×?????·?10??
    NRFWriteReg(W_REGISTER+RF_CH,0x40);       // ?????????¨??0x40
    NRFWriteReg(W_REGISTER+RF_SETUP,0x07); // ??????????1Mbps??·???????0dBm???????ù·??ó?÷????
