Generic QSPI interface to communicate with Sensor via High Density Connector

Hello Dear Arduino Portenta Community,

I have already a running implementation for a STM32H7 single core MCU using its QSPI interface to communicate with a sensor.

Now I did some research if it would be possible to adapt my implementation for the Arduino Portenta H7 board using the high density connectors (HDC). Unfortunately some details are still unclear for me. I found that the SRAM is using one QSPI interface and there are several QSPI labeled pin within the HDC, but is it possible to combine them to a complete functional QSPI interface with full control over the protocol and its pins and parameters using the STM32 H7 HAL.

For any hints, answers or sharing own experiences I would be very grateful.
I hope there is a way to make this setup possible, my sensor and its application field is still not (or barely) represented in the Arduino and Maker space and it would be a pleasure for me to change this. :slight_smile:

Cheers,

Interesting project but we are not a free design or code writing service. We will be happy help out with your design and or code but first you have to make an attempt to design it, write it, post it and explain what is not working properly.

As there is hardware it is always best to post links to technical information as there are many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post using the language of electronics, an annotated schematic, (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here, they are wiring diagrams, great for assembly lousy for troubleshooting.
