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

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

What is "VSPI"?
Free book on ESP32 available here: https://leanpub.com/kolban-ESP32

ESP32 features three SPIs (SPI, HSPI and VSPI) in slave and master modes. Also known as SPI1, SPI2, SPI3?kolban wrote:What is "VSPI"?
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
