Hi Torsten,

I managed to adapt your ADCaptureRunFree to work with a float array.
Since I could not find a suitable algorithm on the internet, I figured out
one myself. Because I need only to convert integers between 0 and 1023,
it is much simpler then the algorithms I found on internet.
I attached the results. Hope you like my first attempt of asm programming.

Thanks for the asm spectrum analyzer files. They look promising (fast!) but
also complicated. I will study them and let you know if I can use them.

Regards,
Pepe
