Compare not working with Boolean AND

[MasterLover]

Sound from a microphone is being inputted into the daq assistant.

Can anyone tell me why it isn't working or is there a different way for the two conditions to be met without using this method.

A little backround on the rest of the code. The two writes are two LED's that are to be set off at certain sound levels.

Thanks

You need to get rid of the evil dynamic data type. I have no idea what the assistant is set for but you need to convert to a dbl so you are ANDing two Boolean. If you are taking multiple samples, you have to decide what you want - max value, mean, etc.

The assistant is acquiring voltage. That was the only way we learned how to acquire the sound by. I think its taking the amplitude level? How would I convert to dbl? First year using labview

Please look at the daq assistant and see if you are acquiring a single sample our multiple ones. That is extremely basic knowledge. You should understand the difference between a scalar and a waveform with multiple points.

There is the Convert from Dynamic Data function. Pick the type that meets the type of sampling. To single dbl or to array. For an array, you have to decide what part of the waveform you want and as I already said, it could be the max value or the mean. It's your waveform, so that's your decision.

No worries, we all have had a first year.  Here is some free training if you are interested.

Basically the DAQ Assistant is the easy way to do things but it hides many of the powerful features of DAQ.  Writing the code with the DAQmx API is more time consuming, but allows for more control, and more features.  You won't find any DAQ Assistants in my real code, only for quick debug.
