SPI quad library / example

[Langelot]

Hello everyone,

I am trying to send data from an ESP WROOM 32 to an FTDI FT4222 chip using SPI QUAD to get hi speed USB data transfer between ESP and USB devices. I made a PCB in accordance with FTDI recommendations.
I am using the Arduino IDE. I searched on the internet but I can't find any library or working example of SPI QUAD communications.

Does any one have some code to share or a starting point?

Thank you.

Does someone have an idea ?

I'm in the same boat - did you (or anyone) ever find an answer to this?
