在调试24l01时，寄存器配置都正常，在发射数据时IREF会出现一个方波，IRQ脚也会出现发送完毕的低脉冲信号，但是检测VDD_PA，ANT1，ANT2都无脉冲信号出现，这应该还是数据没有通过天线发射出去，请问哪位高手知道问题在哪里不？
还有如何察看发送地址寄存器的地址值？
配置及发送配置程序如下：
自动应答及自动重传禁止，通道0允许
void nRF24L01_TxPacket(unsigned char * tx_buf)
{
CLR_CE();
//SPI_Write_Buf(WRITE_REG + TX_ADDR, TX_ADDRESS, TX_ADR_WIDTH); //
//SPI_Write_Buf(WRITE_REG + RX_ADDR_P0, TX_ADDRESS, TX_ADR_WIDTH);
SPI_W_Reg(FLUSH_TX);
SPI_RW_Reg(WRITE_REG + CONFIG, 0x5c);
SPI_RW_Reg(WRITE_REG + EN_AA, 0x00);
SPI_W_Reg(FLUSH_TX);
SPI_RW_Reg(WRITE_REG + EN_RXADDR, 0x01);
SPI_RW_Reg(WRITE_REG + RX_PW_P0, TX_PLOAD_WIDTH);
SPI_RW_Reg(WRITE_REG + STATUS, 0x7e);
SPI_Write_Buf(WR_TX_PLOAD, tx_buf, TX_PLOAD_WIDTH);
SPI_RW_Reg(WRITE_REG + CONFIG, 0x5e);
SET_CE();
Delay_10us(1);
CLR_CE();
Delay_10us(13);
SPI_RW_Reg(WRITE_REG + STATUS, 0x20);
SPI_W_Reg(FLUSH_TX);
//sta=SPI_Read(STATUS); // read register STATUS's value
//SPI_RW_Reg(WRITE_REG+STATUS,SPI_Read(READ_REG+STATUS)); // clear interrupt flag(TX_DS)
}
/**************************************************/
void Config_nRF24L01()
{
CLR_CE();
SPI_RW_Reg(WRITE_REG + CONFIG, 0x3e); //Enable CRC;CRCO:2Byte;PWR_UP:1;PRIM_RX:PTX
SPI_Write_Buf(WRITE_REG + TX_ADDR, TX_ADDRESS, TX_ADR_WIDTH);
SPI_Write_Buf(WRITE_REG + RX_ADDR_P0, RX_ADDRESS, RX_ADR_WIDTH);
SPI_RW_Reg(WRITE_REG + EN_AA, 0x00); // Disable auto ack
