我正在编写一个程序来监视从串行端口(从 arduino)发送的命令并将击键发送到各种其他程序。
我在我的事件中放置了一个调度程序,但它只会运行一次......我已经单步执行了代码,它第一次一直运行,但第二次没有。
private void portReadEvent(object sender, SerialDataReceivedEventArgs args)
{ //break here
Action dump = delegate()
{
dumpInfoText(serialPort.ReadExisting());
}; //create my deligate
txt_portInfo.Dispatcher.Invoke(dump); //run dispatcher
}
private void dumpInfoText(string text)
{
string completeCommand = "";
foreach (char C in text)
{
if (serDump.Length <=8 && (C != (char)0x0A || C != (char)0x0D)) //check
{
serDump = serDump + C; //add char
}
if (serDump.Length == 8) //check to see if my info has a complete command (serDump is global)
{
completeCommand = serDump; //move to complete
serDump = ""; // reset dump
if (C == (char)0x0A || C == (char)0x0D) //dont add crlf
{
serDump = serDump + C; //add char
}
}
if (completeCommand.Length == 8)
{
txt_portInfo.Text = txt_portInfo.Text + completeCommand; //do something with it.
}
}
