Hi,
I had a look at AN4255: FFT-Based Algorithm for Metering Applications available here and would be interested in evaluating this metering library but unfortunately I could not find it anywhere.
There is no associated AN4255SW zip file as for many other application notes and the only resource I could find was the Filter-based variant of the library for another application note (AN4265) --> AN4265SW: http://www.freescale.com/webapp/Download?colCode=AN4265SW
I tried to change the code in the URL to point to AN4255SW but this resource does not exist.
Could someone point me to an archive containing the required sources/library/headers for the meterlibfft.a referenced in Chapter 5 Metering library of the application note ?
Thanks for any hint,
Romain

Hi Romain,
The FFT-Based Algorithm metering library require customer to sign NDA agreement.
So, please contact with your local Freescale sales or Freescale distributor, who can help to get that meterlibfft.a file.
Freescale distributor network is here.
Wish it helps.
best regards
Ma Hui

Hi Ma Hui,
Thanks for the quick reply and helpful information. We'll contact our official representative to go ahead with it and sign the appropriate NDA.
It would be helpful to put this information directly in the Application Note AN4255. Since the Application Note is public I would have expected to find the code also publicly available.
Necvertheless thanks for the help and best regards.

Hi Romain,
the AN4255SW.zip file has just been put on web now - see the associated file of AN4255. This library is compiled for IAR, CW, Keil, inlcuding also header files. There are not source files for the FFT metering library.
