关于NRF24L01的，求解

<p>SPI_NRF_Write(SPI1,NRF_WRITE_REG+TX_ADDR,buf,5);&nbsp; <br />
想问下大神为何跳不出&nbsp; while (SPI_I2S_GetFlagStatus(SPIx, SPI_I2S_FLAG_RXNE) == RESET);这条语句,怎样让RXNE置1额<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
*************************************************************************<br />
u8 SPI_NRF_Write(SPI_TypeDef* SPIx,char CMD,unsigned char* WBuff,unsigned char ByteNUM)<br />
{<br />
&nbsp;unsigned char i,status; <br />
&nbsp;SPI1_CE_LOW();<br />
&nbsp;SPI1_NRF_CSN_LOW();//使能片选<br />
&nbsp;<br />
&nbsp;status=SPI_RW_Byte( SPIx , CMD);<br />
&nbsp;for(i=0;i&lt;ByteNUM;i++)<br />
&nbsp;{<br />
&nbsp;&nbsp;&nbsp;&nbsp; SPI_RW_Byte( SPIx,*WBuff++);<br />
&nbsp;&nbsp; // printf("写入第%d个数据\r\n",ByteNUM);&nbsp;&nbsp; <br />
&nbsp;}<br />
&nbsp;SPI1_NRF_CSN_HIGH();//<br />
&nbsp;return status;<br />
}//SPI_NRF_Write()<br />
************************************************************************************************<br />
u8 SPI_RW_Byte(SPI_TypeDef* SPIx,unsigned char Byte)<br />
{<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; while( SPI_I2S_GetFlagStatus(SPIx, SPI_I2S_FLAG_TXE) == RESET);&nbsp; //查发送缓冲器是否为空，空即可以发送<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SPI_I2S_SendData(SPIx, Byte);&nbsp;&nbsp; //库函数：发送一个字节<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //当SPI接收缓冲器为空时等待<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <span style="color:#e53333;">while (SPI_I2S_GetFlagStatus(SPIx, SPI_I2S_FLAG_RXNE) == RESET);&nbsp;</span><br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return SPI_I2S_ReceiveData(SPIx);<br />
}//SPI_RW_Byte()<br />

检查配置。
