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 was asking about physically reworking the board with a soldering iron, not changing the code. One of the issues with the development kits is the number of GPIO pins used for all manner of things -- buttons, LEDs, etc. -- and the PCA10056 adds to that with the QSPI flash tying up pins for DIO2 and DIO3. I'd like to see Nordic produce "dumber" boards that didn't include so many buttons and LEDs.
