8051 based spectral analyser

[Borges]

Greetings,

I am working on a project that consists in creating a spectral analyser for the power line using the 8051 and the ADC0808 for analog to digital conversion. In the LabVIEW I am trying to sample the waveform of the power line and use the FFT algorithm to perform the spectral analysis with 0Hz to 2.5kHz of range.

Do you think that is possible to use this uC with no problems to perform this application with the Instrument I/O Assistant? Here is the screenshot that what I am trying to do.

Observation: The frequency of the desired signal that I am trying to sample is equal to 60Hz and the ADC0808 has a conversion time equal to 100us.

Thanks,

Borges -

The I/O Assistant is used to help you establish communication with serial, GPIB, Ethernet devices. It does not, however, process signals in any way.  You should be able to establish communication without any problems using the I/O Assistant.

To perform an FFT analysis of your signal, you will need to use one of the many signal processing VIs in LabVIEW. There are express VIs that do Spectral Measurements as well.  

I hope this helps
