CCSC software for PIC18F27K40 for make a FFT from 0Hz to 1Khz of a digital Microphones

I will do this for you. Please give me all the details about this so that I can start working on it.

Hi I am Khled from Egypt PIC 18F27K40 has 24 x 10-bit ADC channels so you don't need external ADC It also can work with a CPU speed of 16 MIPS this will help us to prevent any delay due to complex calculations If you already built your hardware please send me your schematic .if not i found a lot project on the web similar to your project . I can send the link to you they may help in your design thank you
