DSP怎么向串口发送数据呢？比如我想发送一个变量last_ad_result的具体值，我用语句

while(SciaRegs.SCIFFRX.bit.RXFFST !=1) { }

&nbsp; &nbsp;&nbsp; &nbsp;ReceivedChar = SciaRegs.SCIRXBUF.all;

&nbsp; &nbsp;&nbsp; &nbsp; msg = &quot;&nbsp;&nbsp;The temperature is:last_ad_result\0&quot;;
&nbsp; &nbsp;&nbsp; &nbsp; scia_msg(msg);

&nbsp; &nbsp;&nbsp; &nbsp; i = 0;
&nbsp; &nbsp; while(msg != '\0')
&nbsp; &nbsp; {
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;scia_xmit(msg);
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;i++;
&nbsp; &nbsp; }

void scia_xmit(int a)
{
&nbsp; &nbsp; while (SciaRegs.SCIFFTX.bit.TXFFST != 0) {}
&nbsp; &nbsp; SciaRegs.SCITXBUF=a;

}

但是用串口助手显示的是The temperature is:last_ad_result啊，而不是The temperature is:某个数值啊
