That's great! You solved the problem. And... God, It's slave mode! I missed it. ;)

Hello

It seems taking a break and attacking this issue in the morning with a cup of coffee was a good idea.

monpetit was almost correct except that the #define that needed enabling was SPISx_ENABLED (for slave mode), not SPIx_ENABLED. I somehow overlooked this several times yesterday as they looks so similar.

Nordic SPI Slave example defines by default:

#define SPIS1_ENABLED 1

However Nordic template project does not, so must be set if porting..

Thank you for your help :)

Yes the header is included in both main.c and spi_slave_example.c where the functionality is employed.

does the c file which is failing to compile actually include the header file in which you define these things, either directly, or indirectly?

How interesting... I haven't met a problem like this. If you solve it please share with me.

FYI I have tried this with a fresh new template project from SDK 10 to try and isolate anything I may have done with my template modified for AN36. Essentially I repeated exactly what I did in my initial post (add nrf_drv_spis, including files etc.). Once again the same build errors show, so I can be sure that so far it is not to do with my meddling as far as getting the template to do what I want for AN36.

It should be using SPI1 so I set "#define SPI1_ENABLED 1" in the same file but the exact same errors show.

Interestingly, the example provided with SDK 10 does not have any of them enabled, but it appears to build and work fine...

*edit: Pins are configured the same way as in the SDK8.1.1 example which is in the spi_slave_example_init() which is according to the board header, in my case custom board (almost same as pca10028.h) so this must explain why it works without touching nrf_drv_config.h: spis_config.miso_pin = SPIS_MISO_PIN; spis_config.mosi_pin = SPIS_MOSI_PIN; spis_config.sck_pin = SPIS_SCK_PIN; spis_config.csn_pin = SPIS_CSN_PIN;

When you use nrf_drv_xxx components you should modify header file "nrf_drv_config.h". Open it and find definition SPI0_ENABLED and modify it to 1.

#define SPI0_ENABLED 1

And you can assign SPI pins to your taste.

#define SPI0_CONFIG_SCK_PIN         2
#define SPI0_CONFIG_MOSI_PIN        3
#define SPI0_CONFIG_MISO_PIN        4
