I want to know the number of SPI device of nrf52840DK, if there has only one SPI GPIO.

I have the same problem, could you tell me how you solved it?

Hi KV,

I see the same issue. I see the CS go low, clock signals as well as data that my Master MCU is supposed to send out on the MOSI line, but the MISO line is always the default char (255) and I do not get to the NRF_DRV_SPIS_XFER_DONE. Did you resolve your issue? If yes then how?

Hi Sylvain,

Where in the SPI master code did you put the delay? After the master had sent a byte? Please let me know, I am having the same issue.

Now it works, I had to put a delay on my master SPI Nucleo board ...

I have the same problem and I use the SPIS_PCA10056 example. Here's my definition of pin :

#ifndef APP_SPIS_SCK_PIN
#define APP_SPIS_SCK_PIN 47
#endif

#ifndef APP_SPIS_MISO_PIN
#define APP_SPIS_MISO_PIN 46
#endif

#ifndef APP_SPIS_MOSI_PIN
#define APP_SPIS_MOSI_PIN 45
#endif

#ifndef APP_SPIS_CS_PIN
#define APP_SPIS_CS_PIN 44
#endif

#ifndef APP_SPIS_IRQ_PRIORITY
#define APP_SPIS_IRQ_PRIORITY 7
#endif

I don't undertsand why it doesn't work ...

It should work. Which pins are you using? Are you using the SPIS driver?
