Hello Ixx,
From taking a look at your program, as far as I can tell, the
code inside the loop is creating a pulse train, and using another
single pulse generation task to control how long to generate the
initial pulse train. The Wait + (ms) VI is used to prevent the
tasks from going directly from being started to being cleared, and they
are a necessary part if you want your program to output as many pulses
at each frequency that you have entered into the 'number of pulses'
control on the front panel. It seems that if you want to try to
transition between these different frequencies more smoothly, you
should generate more intermediate frequencies by increasing the
'Samples' input of the Ramp Pattern VI. If you want to include
more intermediate frequencies, but want to transition from your lowest
frequency to highest in the same amount of time, then you will have to
generate less pulses at each frequency by lowering the value in the
'number of pulses' control.
Have you considered programming with NI-DAQmx functions as opposed to
these Traditional NI-DAQ functions? They are much easier to use
and actually perform better in almost all applications. NI-DAQmx
requires that you have LabVIEW 7.0 or later, and that your DAQ device
is new enough to support it, which you can check
here.
I hope this helps!
