i want to use the FFT e-meter library on my TWR-KM34Z50. The problem is there is no description of the function "EnergyCalculation" (in AN4255, AN4847). The only reference to that function i have found is in DRM149. The function is used in the "Kinetis-M Two - Phase Power Meter Reference Design" Firmware. Is it possible to get that firmware, so i can see how to implement the function?
