RF433写不到TXFIFO

jidian0177

现在调试CC1101的无线通信，普通寄存器可以写入，可是写不到TXFIFO，卡到红色那句

void CC1101SendPacket( INT8U *txbuffer, INT8U size, TX_DATA_MODE mode )

{

    INT8U address;

    if( mode == BROADCAST )             { address = 0; }

    else if( mode == ADDRESS_CHECK )    { address = CC1101ReadReg( CC1101_ADDR ); }

    CC1101ClrTXBuff( );

    CC1101WriteMultiReg( CC1101_TXFIFO, txbuffer, size );

    CC1101SetTRMode( TX_MODE );

delay_us(500);

    while(! GPIO_ReadInputDataBit( GPIOC, GPIO_Pin_4 )  );//while(！GDO0)

    while( GPIO_ReadInputDataBit( GPIOC, GPIO_Pin_4 )  );//while(GDO0)

    CC1101ClrTXBuff();

}

会是什么原因呢？

正点原子
