Hi WiFive,

Would you know if in this revision 3 of the chip, the "i2s with dma" module can transfer words smaller than 32 bits, ie 8 bits per transfer ?

How many megahertz in parallel output mode does the i2s module with dma support in this new review ?


Thank's.

I don't think there are any changes to i2s or dma

As far as i know the module i2s with dma of esp32-s2 supports these features.
So i would like to know if in revision 3 of esp32 maybe they used the same module as esp32-s2.

WiFive is correct; there are no changes in DMA or I2S in ECO3.
