Confirmations about ESP32 peripherals

Re: Confirmations about ESP32 peripherals
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?

Re: Confirmations about ESP32 peripherals
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.
Re: Confirmations about ESP32 peripherals
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 youESP_Sprite wrote:No idea about the SPI, but the ESP32 is going to have a modified I2S module.

Re: Confirmations about ESP32 peripherals
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.
