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 ;)

Hi Julie

We have to wait for the production version of the part before we can make the USB dongle, so it will be a bit of a wait unfortunately (expected Q1 2018). Because of the smaller size, and to avoid using non standard header sizes, it won't have all GPIO's broken out. Currently we are looking at around 14 available GPIO's, with some of the remaining GPIO's used for things like LED's and buttons.

Best regards
