I have a CS4344 DAC connected to my STM32F407 outputting sound at a 44.1kHz rate with DMA and I2S and I would like to output and envelope signal through the internal DAC of the STM32F4, in sync with the I2S.
I could use a timer at a frequency of 44.1kHz but the 2 outputs wouldn't be in sync.
Is it possible to use the I2S WS clock to trigger the DAC conversion? So that everytime a sample is sent through I2S, a sample is converted through the internal DAC?
Thanks in advance!
