Im running a stm32 L432KC nucleo with the following settings.
clk = 80 Mhz Spi to to sd card module Prescaler 2 Counter period 1813 buffer size 500
Half buffering to play .wav music file at a freq of 22050 hz. 8bit mono
Im getting strange noise from the DAC output. And my clk seems to be off even though ive set it up in the correct way.
I have tried switching mcu, adjusting clk, 5 different amp circuits, code seems to be fine. When playing a 440hz sinewave i get the following outputoscillocope on DAC1 output
