Re-work hints for QSPI flash on PCA10056

[Julie H]

The design I'm working on will tentatively use "Original SPI" (like "Original Coke" ...), so I started cutting up the QSPI bridges to disconnect DIO2 and DIO3 (which are also other things ...) prior to pulling them up to Vcc.

Has anyone else done this? I'm comfy working under a microscope, but I'm an old geezer fart and I'm always looking for huge pads and buttons and knobs and dials I can use.

Hi Julie

There are several standard SPI interfaces in the nRF51840, both master and slave, so you shouldn't need to repurpose the QSPI interface for this.

If you just need standard SPI I would simply use the SPIM0 or SPIM1 interface instead ;)

Best regards

I totally understand - the nRF52840 will be a great part in full-sized applications on account of having 48 GPIO pins. I'm not sure a 48+ pin "dongle" would be a "dongle" anymore.

I may have found a silk screen issue. I have to head into the office to try and resolve a completely different issue. As soon as I'm convinced the silk screen problem is real I'll post another question.
