try { GlobVar.nLeng = GlobVar.TheMCU.serialPort1.BytesToRead; if ((GlobVar.nLeng > 0) && (GlobVar.nLeng < 30000)) { for (int s = 0; s < GlobVar.nLeng; s++) { nLength = GlobVar.TheMCU.serialPort1.Read(bLocalBuf 0 1); if (nLength == 1) { if (bLocalBuf[0] == 0xc9 && GlobVar.nSOMFlag == 0) { GlobVar.nRindex = 0; GlobVar.RxBufferData[GlobVar.nRindex++] = bLocalBuf[0]; GlobVar.nSOMFlag = 1; } else if (bLocalBuf[0] == 0xcf && GlobVar.nSOMFlag == 1) { Rx_Checksum(); // To compare the recv data Checksum // GlobVar.RxBufferData[GlobVar.nRindex++] = bLocalBuf[0]; if ((GlobVar.RxBufferData[2] == 0x01)) Rx_LinkCheck(); } catch(Exception ex) { //MessageBox.Show(ex.Message); } }
