SPI3 missing in SDK v14.2.0 for nRF52840

[Jakob]

I am trying to enable SPI in spi_config.h but SPI3 is missing for the nRF52840.

I need DCX functionality, and from the OPS for nRF52840 it looks like it is only SPI3 that has support for it.

Is the SDK still missing support for SPI3?

It's simply because SPI3 isn't working on nRF52840 EngA revision so while there is no chip to use it on there is also no support in SDK. Read errata.

By February 2018 the nRF52840 will go into mass production, with the SPI3 interface included. If you need something before that you should talk to your Nordic sales contact (if you don't have one send me a PM, and will put you in contact with your local sales manager).

Hi ovrebekk,

can you tell where can find the example of SPI3 on nRF52840?

Hi Xiao

We will have an example for SPIM3 in SDK v15.0.0, which is planned to be released at the same time as the nRF52840 production launch at the end of the month.
