ADAU1761 - How would you do a Phase Locked Loop?
Hi everyone, I did my own version of a Phase Locked Loop, like normally used for frequency modulation. Everything works fine in SigmaStudio, but when I transport it to a microcontroller I have some bu

ADAU17xx Sigma DSP Readback cell inconsistent read with MicroController
Hi, I can read a fixed DC source value (positive and negative) with my MicroController by using a DSP readback block. I can also read a sinus output in the MicroController using the DSP readback. BUT,
