Dear all, I am going to design a simple data aquisition system. I am newbie to FFT and uC. See if there is any recommendation. Thanks. Bill
"I am going to design a simple data aquisition system. I am newbie to FFT..." Do you actually need the FFT to do acquisition? If not, you could consider doing just the acquisition on the 8051, and then pass the data to another system (eg, PC) to do FFT processing, etc...
