Hi,
I have a problem with read implementation. I explain you.
I need to read EEprom and so: 3 pin (chipselect, DI, clock) set output mode and 1 set input (DO).
I initialize read port-pin:
private struct PortPinSettingRead
{
public DigitalSingleChannelReader reader;
public Task digitalInputReadTask;
public UInt32 pin;
}
PortPinSettingRead portPinSettingRead;
portPinSettingRead.digitalInputReadTask = new Task();
portPinSettingRead.digitalInputReadTask.DIChannels.CreateChannel("dev1/port11/line3", "", ChannelLineGrouping.OneChannelForEachLine);
portPinSettingRead.digitalInputReadTask.Control(TaskAction.Verify);
portPinSettingRead.reader = new DigitalSingleChannelReader(portPinSettingRead.digitalInputReadTask.Stream);
//READING
public int readDI(){
try
{
return portPinSettingRead.reader.ReadSingleSamplePortInt32();
}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
return -1;
}
}
I see by oscilloscope, that when I call readDI() function, the output pin go to 0.
Is it possible?
Thank you
