C# on PC: how to toggle DTR to Prop/FT231X?

Tracy Allen

The programmer I'm working with does not know how to control DTR using C# on the PC. It would be really convenient on my side with the propeller if the PC could do that in order to reset the prop to a known state. Does anyone have any quick tips or links I could pass on about how to work it? I'm clueless about C#.

As you have to go through the virtual comport, I guess this way below is the way to do it:
I have not tried it as I used a UART HID devices that can toggle any pin manually.

using (SerialPort serialPort = new SerialPort("COM1", 9600))
{
    serialPort.Open();
    while (true)
    {
        Thread.Sleep(1000);
        serialPort.DtrEnable = true;
        Thread.Sleep(1000);
        serialPort.DtrEnable = false;
    }
    serialPort.Close();
}
