I tried to write to analog output channel with an external trigger source - PFI0. The write operation times out even after I write values 0 and 1 to the digital channel- Dev1/PFI0 within the timeout period. The error message obtained is given below
Wait Until Done did not indicate that the task was done within the specified timeout.
Increase the timeout, check the program, and make sure connections for external timing and triggering are in place.
Task Name: _unnamedTask<17>
Status Code: -200560
The code that I used for the write operation is given below. The write operation succeeds when I set the source terminal of the Sample Clock as internal source of the device in the API DAQmxCfgSampClkTiming.
What could be the issue with the following code?
double dValues[2]{ 2, 2 };
int32 nError = DAQmxCreateTask("", &oTask);
nError = DAQmxCreateAOVoltageChan(oTask, "Dev1/AO1", "", -3.25, 3.25, DAQmx_Val_Volts, nullptr);
nError = DAQmxCfgSampClkTiming(oTask, "PFI0", 50.0, DAQmx_Val_Rising, DAQmx_Val_FiniteSamps, 2);
nError = DAQmxCfgDigEdgeStartTrig(oTask, "PFI0", DAQmx_Val_Rising);
nError = DAQmxWriteAnalogF64(oTask, 2, 1, 60, DAQmx_Val_GroupByChannel, dValues, nullptr, nullptr);
nError = DAQmxWaitUntilTaskDone(oTask, 60);
