I am trying to assess feasibility of using a STM32f411 in combination with 2 4 channel class D amplifier chips (FDA4100LV) to make a USB connected surround amplifier for my computer.
I have the skills to make the USB communication and DMA buffering work. What I am uncertain about is how to use 4 i2s peripherals in sync. Each i2s peripheral seems to be outputting its own clock when configured in master mode. Is it possible to have one peripheral output the clock + 2 channel data and the 3 other peripherals output only 2 channel data on the same clock as the first i2s?
I am sorry if this question was asked before. I am dealing with quite some time pressure here and I do not have the time to do my own proper research on this matter. If someone could point me in the right direction, it would help me a lot.
