ADP sink example ok ESP-IDF with internal DAC

Postby fbeaulier » Tue Dec 04, 2018 2:15 pm

Hi ,
I'm would like to try the ADP sink example configured with internal DAC.
I seems to run, i have some signals on GPIO 25 and 26 as expected but it is completely saturated.
I'm sending a pure sinus from my phone and i get a square (at the right frequency) even at low volume.
Besides it seems that the DAC is in fact a PWM ?
Anyone had success with this example ?
Any tips on how to solve that ?

Thanks

François
