Step function generator

[frenchy 43]

Hi,

I need to create a step function generator (exponential functions, sine function, etc...) to send functions to a high speed length controller (via a DAQ board, of course) which will treat my signal to control a motor...

Actually I really don't know how to do this program, so if someone could help me...

Thank you !

Hi,

You can find many different waveform functions in waveform generation to output the signal you want. By using a NI DAQ card with some simple analog output example programs, you can learn how to use DAQ functions with the waveform function to generate the wanted signal.

To elaborate.

The function generators can be found on the functions >> waveform >> analog waveform >> waveform generation palette. There are shipping examples that show how to control the analog output of DAC cards. Open LabVIEW 7.1 >> help >> find examples >> Choose "Hardware Input and Output". You will have to navigate from here to what applies to your system. I suspect it will be something like DAQmx >> Analog Generation >> Voltage.
