CC1150的发射问题

TI的工程师：

      您好，我用CC1150做射频发射端，现在我碰到的问题是： CC1150复位、寄存器初始化都能正常运行。但是我让CC1150发送数据时，此时我判断GDO0口的状态来判断发送进程。每次程序跑到while (!GDO0)；这条语句时，程序就死在这里了。但是同样的程序我用CC1101跑。却没有问题。下面是我的初始化：频率是410M，波特率是250K。

发送程序：

void halRfSendPacket(INT8U *txBuffer, INT8U size)
{
halSpiWriteReg(CCxxx0_TXFIFO, size);
halSpiWriteBurstReg(CCxxx0_TXFIFO, txBuffer, size); //写入要发送的数据

halSpiStrobe(CCxxx0_STX); //进入发送模式发送数据

// Wait for GDO0 to be set -> sync transmitted
while (!GDO0);
// Wait for GDO0 to be cleared -> end of packet
while (GDO0);
halSpiStrobe(CCxxx0_SFTX);
}

死在 while(!GDO0), 那实际用示波器测量GDO0是什么情况？

你用的是什么板子？自己做的还是TI的参考板? MCU是哪颗？

另外可以查看一下 TX_FIFO 的状态，看是不是underflow了。

因为CC1150只支持发送，可以尝试把 GDO0_CFG[5:0] 设置为0x05 试试。

根据你们的提示，查到问题了。由于我们硬件工程师的失误，造成PCB问题。给你们添麻烦了。谢谢！
