用msp430和nrf24l01發送數據，電腦端也是nrf接收，接收不到是為啥

void SetTX_Mode(void)
{
      RF24L01_CE_0 ;

      SPI_Write_Buf(WRITE_REG + TX_ADDR, TX_ADDRESS, TX_ADR_WIDTH);
      SPI_Write_Buf(WRITE_REG + RX_ADDR_P0, TX_ADDRESS, RX_ADR_WIDTH);

      SPI_RW_Reg(WRITE_REG + RF_CH, 0);
      SPI_RW_Reg(WRITE_REG + RX_PW_P0, RX_PLOAD_WIDTH);

   // SPI_RW_Reg(WRITE_REG + RF_SETUP, 0x0F); //設置TX發射參數,0db增益,2Mbps,低噪聲增益開啟
      SPI_RW_Reg(WRITE_REG + RF_SETUP, 0x07); //設置發射速率為1MHZ，發射功率為最大值0dB

      SPI_RW_Reg(WRITE_REG + CONFIG, 0x0e);
      ms_delay(1);
      RF24L01_CE_1;

}
有哪里不對么

本站有文章《51單片機玩轉NRF24L01》看一下，參考里面的方案逐步測試一下！提醒你，有可能是硬件問題！

為什么沒有將數據寫到txbuf中的那一條語句呢

這個是我的你可以參考下，

void TX_Mode(void)
{
CE=0;

    SPI_Write_Buf(WRITE_REG + TX_ADDR, TX_ADDRESS, TX_ADR_WIDTH); // Writes TX_Address to nRF24L01
    SPI_Write_Buf(WRITE_REG + RX_ADDR_P0, TX_ADDRESS, TX_ADR_WIDTH); // RX_Addr0 same as TX_Adr for Auto.Ack
    SPI_Write_Buf(WR_TX_PLOAD, tx_buf, TX_PLOAD_WIDTH); // Writes data to TX payload

    SPI_RW_Reg(WRITE_REG + EN_AA, 0x01);    // Enable Auto.Ack:Pipe0
    SPI_RW_Reg(WRITE_REG + EN_RXADDR, 0x01);  // Enable Pipe0
    SPI_RW_Reg(WRITE_REG + SETUP_RETR, 0x1a); // 500us + 86us, 10 retrans...
    SPI_RW_Reg(WRITE_REG + RF_CH, 40);       // Select RF channel 40
    SPI_RW_Reg(WRITE_REG + RF_SETUP, 0x07); // TX_PWR:0dBm, Datarate:2Mbps, LNA:HCURR
    SPI_RW_Reg(WRITE_REG + CONFIG, 0x0e);    // Set PWR_UP bit, enable CRC(2 bytes) & Prim:TX. MAX_RT & TX_DS enabled..

CE=1;
