Synchronize internal DAC transfer to I2S DMA transfer

Posted on August 16, 2016 at 20:12

Hi!

I have a CS4344 DAC connected via I2S to my STM32F407, converting values at a rate of 44.1kHz.

In parallel, I would like to convert values through the internal DAC, at the same rate, in a synchronized way (everytime a value is converted on the CS4344, it's also converted in the internal DAC).

For example, it would work if I could use I2S' WS clock to trigger the internal DAC's conversions. Is it possible? If yes, how?

Thanks in advance!
