关于上位机VisualScope的问题

飘渺孤鸿~ · 发表于 2015-4-2 14:21:12

程序里边已经添加了上位机的协议，然后串口助手可以收到数据，但显示波形的上位机却没反应，请问是什么原因呢，谢谢大家！

这个是通信协议，然后我直接调用WirelessSerial(100,200,300,400)；没反应

unsigned char TxBuf[10] = {0,0,0,0,0,0,0,0,0,0};

void SCI_sendstring(unsigned char *a,unsigned char stringlen)
{
unsigned char i;
  for(i=0;i<=stringlen;i++)
      Uart_SendByte(UART4,*(a++));
}

unsigned int CRC_Check(unsigned char *Buf, unsigned char crc_count)
{
unsigned short CRC_Temp;
unsigned char i,j;
CRC_Temp = 0xffff;

for (i=0;i<crc_count; i++)
{
      CRC_Temp ^= Buf[i];
      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 WirelessSerial(float a,float b,float c,float d)
{
  int num;
  unsigned char *data;

#if 1
  num = (int)a; //Speed
  data = (unsigned char *)&num;
  TxBuf[0] = *data;
  data++;
  TxBuf[1] = *data;

  num = (int)b;    //MotorPWM
  data = (unsigned char *)&num;
  TxBuf[2] = *data;
  data++;
  TxBuf[3] = *data;

  num = (int)c;       //angle
  data = (unsigned char *)&num;
  TxBuf[4] = *data;
  data++;
  TxBuf[5] = *data;

  num = (int)d;
  data = (unsigned char *)&num;
  TxBuf[6] = *data;
  data++;
  TxBuf[7] = *data;
#endif

  num = CRC_Check(TxBuf,8);
  TxBuf[8] = num & 0xFF;
  TxBuf[9] = num >> 8;

  SCI_sendstring(TxBuf,9);
}
