can nRF52840 qspi support multiple devices

[visionwang]

Hi

 nRF52840 has only one qspi interface, can it connect two qspi devices: qspi flash and qspi sram?

Yes, but you'll have to change the CS pin(PSEL.CSN) whenever you want to talk to another device.

Can you supply the code about driving spram?

Thanks.

We do not have an SPRAM example. You'll have to ask the manufacturer of your SPRAM for a general driver and port it to our device.
