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?

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.

ESP32 Price

Hi all,

Do you think it is safe to estimate the esp32 price 1.5 times the esp8266 price? I need that information to make some estimates for a idea I have in mind.

Thank you

Re: Confirmations about ESP32 peripherals

If I remember correctly from the ESP2866 documentation it has hardware SPI however it is used by flash so we can't use it and on ESP32 it looks like there is separate peripherals.

BTW what is HS1d0-d7 HS1clk HS1cmd ?
