ADAU1861 and Lark Studio: measure amplitude and phase spectrum

Category: Datasheet/Specs
Product Number: ADAU1861


I'm considering using FastDSP to measure the amplitude and phase characteristics of a feedback loop. For this, I would need a tone generator or a sample player from memory, but I can't find either in Lark Studio. Next, I would need an FFT component, which I also can't find in Lark Studio. Finally, I could output the result, whether it's FFT or simply the sampled response, to an external MCU. I assume I could do this using the "Memory Read", "Memory Write", and "Memory Signal Write" components, but where can I find examples of their usage (memory address ranges) and the format for writing/reading this through the control port?
