Where can I find the Header File for the nRF52833 ADAA SOC

[RussM]

I'm specifically interested in the predefined SPIMn - SCK, MOSI, MISO, SO pins for this device, so that I can marry this information into my CPU Schematic Page.
Whilst the Table 40: QFN40 Pin Assignments, there is a Note: If SPIM0, SPIM1, or SPIM2 is used with 8 Mbps data rate, the recommended GPIOs for the
clock signal (SCK) are P1.09, P0.04, and P0.31.

Usually, the Header File defines the parameter and pin for each of these SPIMn signals.  The PCA010100.h file bares no resemblance to the 40-pin QFN40 device.

Your assistance would be appreciated

Hi,

I checked the board file and can confirm that it doesn't set the SCK pin as one of those mentioned in the Product spec, instead it uses Pin 27. Most of the board files for the development kits are fairly similar, as the DKs in the nRF52 series isn't that different. If you're making a custom board then the best would be to just start with the PCA10100.h file and modify so that it fits your board. You can use any other GPIO for SCK, just remap them either in the board file or in your application. Just make sure that you doesn't use the pins marked as low frequency/low drive. 

Usually, the Header File defines the parameter and pin for each of these SPIMn signals

 Elaborate a bit more on this. The other boards files uses mostly the same setup as the one used for the nRF52833 board.

Jared,

Thanks for that, I feel a lot better with my design, I was dreading getting a prototype PCB and found that nothing works.

I'll make a customised copy of the PCA10100.h file for when I test the Prototype PCB.

I was finalising my design, and wanted to have most of the code common to the nRF52833 DK

Sounds good! Also, if you're not aware: We offer free design reviews, just create a new Private ticket and attach your Schematic and PCB layout files and one of our HW engineers will take a look at it.
