ESP32 HW SPI : Pins for MOSI, MISO, SCK , ( CS )

[BlackGP]

Hi,

I need to connect ESP32 Spi whit my microcontroller by the SPI interface.

I want use the VSPI.

But what are the correct pinout of the VSPI? Who is MISO?

Who is MOSI?

Interesting question, do you have any software for VSPI ?
I could find some definitions for register etc. but no functions.

What is "VSPI"?

What is "VSPI"?

ESP32 features three SPIs (SPI, HSPI and VSPI) in slave and master modes. Also known as SPI1, SPI2, SPI3?

In master mode
SPID = MOSI = data out
SPIQ = MISO = data in

In slave mode
swapped or same??

The pin of the HSPI is also used for the Jtag , so I can't use HSPI in my project because I need to debugging my applications via Jtag.

In my project I will be using the VSPI interface as a slave.

Question 1
Will my external CPU able to issue AT commands to the ESP 32 through the VSPI interface?

Question 2
I need to interconnect the VSPI interface with my MCU's SPI interface.

Who is MISO and MOSI among these signals: VSPIHD, VSPIQ, VSPID
