QSPI disable addressing

Hi Luke

I've asked internally if it is a way to use the QSPI driver to run a custom display. There is no simple way to just disable the memory addressing, as it is designed as a Flash interface.

If you could upload/link to the datasheet of your display we will have a look, and come back to you with a definitive answer on whether this will be possible using the QSPI driver or not.

Best regards,

Simon

Simon,

Thanks for posting that.

I still do not believe this demo is doing what I would like as the demo is using standard SPI to write to the display. The demo is only using the QSPI module to read from a SPI Flash.

I think everything will work fine if there is a way to disable the addressing feature on the QSPI writes.

Hi Luke

One of our colleagues has made a blog post on exactly running an LCD display using QSPI on the nRF52840. Please check it out, and I hope you find it useful.

Best regards,

Simon
