Confirmations about ESP32 peripherals

[metRo_]

BTW what is HS1d0-d7 HS1clk HS1cmd ?

8-bit SDIO

Is this SDIO free? Do you think it is possible to use it to drive an LCD using DMA?

and by software can I write to a register and the data is sent out to HS1d0-d7 ? It is faster then clock the 8 bits out.

[metRo_]

Where can I get more information on the sd card interface? I tried Xtensa LX6 documentation but doesn't found any public document. Which would be the maximum clock on this interface?

No idea about the SPI, but the ESP32 is going to have a modified I2S module. The DMA capabilities that has will stay, but it will also be able to output/input parallel data so you can e.g. send images to a parallel LCD using DMA.

I want to use I2S module,to read input data.but esp32_datasheet did not say specifically how to use I2S,Can you tell me the specific configuration steps to use?How to operate the register steps?thank you

Sorry, the I2S chapter of the TRM is still in editing. We'll try to update it ASAP, but it'll probably take at least a few more weeks.
