I am trying to find some FFT code for a PIC16F877. If someone could either possibly find some links for me - or suggest some possible code that I could develop or modify.
Would the dsPICs have the FFT formulas inbuilt?
If so - how would you use these inbuilt functions?
Also which dsPIC would you suggest I use? there seem to be a lot of them out there!
There are many dsPICs and yes they have FFT instructions designed to do the math quickly. The dsPIC30F4013 is a 5V 40pin PDIP. You'll need to learn C to work with them. There should be plenty of FFT & dsPIC app notes on Microchips site.
