c# - 等待串口的响应，然后发送下一个数据
我正在从.bin文件中以字节为单位读取数据并将整个字节数据拆分为16-16字节帧，因此我想一个接一个地读取 16 个字节帧并等待第一帧完成其周期。
SerialPort 类的回调方法：
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// Read data from serial port:
byte[] buffer = new byte[serialPort.BytesToRead];
serialPort.Read(buffer, 0, buffer.Length);
StringBuilder sb = new StringBuilder();
List
for (int i = 0; i < buffer.Length; i++)
{
string currentByte = string.Format("{0:X2}", buffer[i]);
response.Add(currentByte);
sb.AppendFormat("{0:X2}", buffer[i]);
}
string responesCode = response[1].ToString();
if (responesCode == "44")
{
// Wait until the first response is not received
foreach (var packet in packetList.Skip(1))
{
// This method which sending the the data
this.ReadByteDataFromFile(packet);
}
}
}
FdBrowseFile_Click按钮点击：
private void FdBrowseFile_Click(object sender, RoutedEventArgs e)
{
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
Nullable
if (result == true)
{
byte[] fileBytes = File.ReadAllBytes(filename);
foreach (byte[] copySlice in fileBytes.Slices(16))
{
var splitedByteArray = copySlice;
if (splitedByteArray.Length != 16)
{
byte[] padd = new byte[16];
var startAt = 0;
Array.Copy(splitedByteArray, 0, padd, startAt, splitedByteArray.Length);
packetList.Add(padd);
}
else
{
packetList.Add(splitedByteArray);
}
}
ReadByteDataFromFile(packetList[0]);
}
}
ReadByteDataFromFile 方法：
public void ReadByteDataFromFile(byte[] packet) {
try {
byte[] mBuffer = new byte[24];
byte[] payload = new byte[16];
int i = 0;
foreach(var bytes in packet) {
payload[i++] = bytes;
}
CheckSumHelper checkSumHelper = new CheckSumHelper();
var ckSum = checkSumHelper.GetCheckSum(payload);
mBuffer[0] = 0x02;
mBuffer[1] = 0x10;
mBuffer[2] = CheckSumHelper.GetBytesFromDecimal(packet[0]);
mBuffer[3] = CheckSumHelper.GetBytesFromDecimal(packet[1]);
mBuffer[4] = CheckSumHelper.GetBytesFromDecimal(packet[2]);
mBuffer[5] = CheckSumHelper.GetBytesFromDecimal(packet[3]);
mBuffer[6] = CheckSumHelper.GetBytesFromDecimal(packet[4]);
mBuffer[7] = CheckSumHelper.GetBytesFromDecimal(packet[5]);
mBuffer[8] = CheckSumHelper.GetBytesFromDecimal(packet[6]);
mBuffer[9] = CheckSumHelper.GetBytesFromDecimal(packet[7]);
mBuffer[10] = CheckSumHelper.GetBytesFromDecimal(packet[8]);
mBuffer[11] = CheckSumHelper.GetBytesFromDecimal(packet[9]);
mBuffer[12] = CheckSumHelper.GetBytesFromDecimal(packet[10]);
mBuffer[13] = CheckSumHelper.GetBytesFromDecimal(packet[11]);
mBuffer[14] = CheckSumHelper.GetBytesFromDecimal(packet[12]);
mBuffer[15] = CheckSumHelper.GetBytesFromDecimal(packet[13]);
mBuffer[16] = CheckSumHelper.GetBytesFromDecimal(packet[14]);
mBuffer[17] = CheckSumHelper.GetBytesFromDecimal(packet[15]);
mBuffer[18] = 0x17;
mBuffer[19] = 0x00;
mBuffer[20] = 0x00;
mBuffer[21] = 0x00;
mBuffer[22] = Convert.ToByte(int.Parse(ckSum, System.Globalization.NumberStyles.HexNumber));
mBuffer[23] = 0x03;
serialPort.Write(mBuffer, 0, mBuffer.Length);
} catch (Exception ex) {
ExceptionHandler exceptionHandler = new ExceptionHandler();
exceptionHandler.HandleException(ex);
}
}
如何为ReadByteDataFromFile方法添加延迟？
