master clock frequency #3

Jente105 commented 1 week ago

firstly, thanks for your work on this subject. I was looking to replace the PCM5102a with a better dac. I noticed that the STM32F411xE configuration could provide the masterclock. what would the frequency at the rated sample frequencies(44.1, 48 and 96 kHz) of your firmware be when masterclock generation is enabled?

thanks,

Hi

Yikes those calculations are above my paygrade I’m afraid

The best is to post your query on the origin of the source code that I am using which is https://github.com/har-in-air/STM32F411_USB_AUDIO_DAC and https://github.com/dragonman225/stm32f469-usbaudio

If you get to a working configuration with an external i2s clock please let me know the details..

Best wishes Tobias van Dyk

Hi

I attach the SCK frequencies from the datasheet page 24

Best wishes TvD
