Hello, I want to send data to the DAC with the I2S protocol (assume we are sending an array) and see a sine wave at the output.
At this point, I would like to ask: Does the DAC in the stm32f407vg model mean the CS43L22 IC or an internal DAC unit in it, and as far as i know, the CS43L22 IC can communicate over i2s, can we communicate with the internal DAC over the i2s line?
Finally, I have the stm32f429l board. Can I communicate this board with the DAC via the i2s line? Or should I procure an external DAC IC?
Thank you in advance for your answers and help.
