stm32H750: Config of SAI4 sample rate in stm32CubeMx

[Poul-Erik]

I have created a clock of 38.4MHz for SAI4A and SAI4B but I am not able to get 24.0kHz sample rate for a I2S 32bit Master input.

All sample rages seams to relate 4.8MHz clock.

Hello Poul,

you really want 24kHz sample rate ? this is no standard frequ. , but ok, lets try:

with pll setting

 

comes close to your 24khz ;

if you want frequ. exact 100% , you must use a matching clock, ie, 49,152 MHz.

ok?
