Hi all
I want to digitize an analog sinus signal of 1 Hz and simultaniously generate an digital pulse in syncronasation with the sinus peaks.
I'm trying to solve this by routing the analog trigger signal on the input channel to an digital output.
I have read all the samples in LabView so please dont direct me to them again. Can someone help me to configure the DAQmx driver for me?
Below you can find my test code but it doesn't work at all. What is wrong?!!
// Create the master and slave tasks
inputTask =
new Task("inputTask");
outputTask =
new Task("outputTask");
// Configure both tasks
inputTask.AIChannels.CreateVoltageChannel("Dev2/ai0", "", AITerminalConfiguration.Differential, -10, 10, AIVoltageUnits.Volts);
outputTask.COChannels.CreatePulseChannelTime("Dev2/ctr0", "", COPulseTimeUnits.Seconds, COPulseIdleState.Low, initialDelay, lowTime, highTime);
// Set up the timing
inputTask.Timing.ConfigureSampleClock("", 1000, SampleClockActiveEdge.Rising, SampleQuantityMode.FiniteSamples, 1000);
outputTask.Timing.ConfigureImplicit(SampleQuantityMode.FiniteSamples, 1);
// Set up the triggers
inputTask.Triggers.ReferenceTrigger.ConfigureAnalogEdgeTrigger("APFI0", AnalogEdgeReferenceTriggerSlope.Rising, level, 2);
outputTask.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger("ai/ReferenceTrigger", DigitalEdgeStartTriggerEdge.Rising);
// Verify the tasks
inputTask.Control(TaskAction.Verify);
outputTask.Control(TaskAction.Verify);
