ADC into FFT

1,198 Views

Hi,

I'm currently working on an Audio Analysis system, based on a DE0-Nano board.

I've built the FFT core and implemented it into the SOPC builder (see attached). However, I'm not entirely sure how to go about connecting it to the ADC output. I assume that the ADC output needs to be written to the memory block that I am using as the Input RAM for the FFT core, but how I go about that escapes me.

I've taken a look at the ADC example, but it's not really been of much help at all with this. All I know is that the ADC output data comes into PIN_A9 on the board, and somehow I need to get that to be read into the FFT. Help!

Thanks.
