WROOM-32 + external SPI devices

[techydude]

Hi guys,
I'm finally trying to wrap my head around the ESP32, specifically with the ESP32-WROOM-32 module, as regards what I can use GPIO6..11 / WROOM-32 pins 17..22 for.

AFAIK these are connected to the 4Mbyte QSPI-Flash chip on the WROOM-32 module?
And those same 6 signals are brought out to the WROOM-32's external pins, but only for the purpose of connecting additional SPI-Flash or SPI-RAM *memory-mapped* devices?
And that those extra external SPI-Flash/SPI-RAM devices will need their own CSx pins, which can be mapped to any other GPIOx?
And I can't use those 6 WROOM-32 pins for general-purpose SPI devices?

My situation is that I'm intending to use a PaPiRus Eink display board (www.adafruit.com/product/3420) which has both the Eink display as one SPI device, as well as a 32Mbit SPI-Flash chip, sharing the same SPI bus with 2 CS signals. If I'm correct in my understanding above, I won't be able to use the QSPI signals for anything; I'll need to put the PaPiRus with its 2 SPI devices on a separate SPI bus (i.e. HSPI or VSPI) on other GPIO pins, right?

Thanks, Anthony.

Yes. In theory it's possible to support other generic SPI devices over the flash SPI bus, but esp-idf does not have support for that yet.
