What do you mean by result is not good?


I have few observations


  • You have useed simulate signal and passed it to the DAQ assistant why are you doing that?
  • Do not keep the DAQ mx configure and the clear task inside the while it will take a lot of time to allocate resource again and again when you create a task inside the loop

Check the attached snippet for using DAQmx (You can optmize it)


The best solution is the one you find it by yourself
