Hi,
I'm new to using DAQmx ANSI C and am attempting to calculate pulse
widths. I have a PCI 6031E series board with SCB-100 break-out
block. I've reviewed the example code, PulseWidth_main.c, provided by
NI that makes use of counters. I modified it to run in a loop (by
creating a buffer, using a while loop, and reading data using
DAQmxReadCounterF64). Unfortunately I am getting the following error:
------------------------------------
DAQmx Error: Pulse width measurement was started while the input signal was active,
and no additional pulses were received, which caused the measurement not to
complete during the specified timeout.
When measuring a single pulse width, make sure the measurement counter is started
before the pulse to be measured is active, or provide a timeout sufficient for at least one
additional pulse to be measured.
Task Name: _unnamedTask<0>
Status Code: -200339
-----------------------------------
Has anyone encountered this problem? Perhaps my hardware connections
are incorrect. I'm using a function generator to generate a 5 V, 10 ms
pulse twice per second, and conencting it to CTR0 source.
