原子哥，虚拟示波器后面那个发送函数怎么写的

[mw_shl_code=c,true]unsigned short CRC_CHECK(unsigned char *Buf, unsigned char CRC_CNT) { unsigned short CRC_Temp; unsigned char i,j; CRC_Temp = 0xffff; for (i=0;i<CRC_CNT; i++){ CRC_Temp ^= Buf; for (j=0;j<8;j++) { if (CRC_Temp & 0x01) CRC_Temp = (CRC_Temp >>1 ) ^ 0xa001; else CRC_Temp = CRC_Temp >> 1; } } return(CRC_Temp); } void OutPut_Data(void) { int temp[4] = {0}; unsigned int temp1[4] = {0}; unsigned char databuf[10] = {0}; unsigned char i; unsigned short CRC16 = 0; for(i=0;i<4;i++) { temp = (int)OutData; temp1 = (unsigned int)temp; } for(i=0;i<4;i++) { databuf[i*2] = (unsigned char)(temp1%256); databuf[i*2+1] = (unsigned char)(temp1/256); } CRC16 = CRC_CHECK(databuf,8); databuf[8] = CRC16%256; databuf[9] = CRC16/256; for(i=0;i<10;i++) USART_SendData(USART1,databuf); } [/mw_shl_code]

就这里的最后一条函数 [mw_shl_code=c,true]USART_SendData(USART1,databuf);对么这样写，咋么在示波器上看不到波形走动呢，COM口设置是对了的，就是这里的发送函数不对感觉，您有着段示波器的例程吗？共享一份吧[/mw_shl_code]
