#1984

Hi,

I am experimenting nrf52840 + enc28j60 (ethernet controller). I am trying to
connect to some ports on board to provide spi functionality, need help in
enabling this setup.

Details about ENC28J60 board are here. I need pin numbers on nrf52 board and SPI configuration setup.

=================    ===================================
NRF52840 PCA10056    ENC28J60 (pin numbers on the board)
=================    ===================================
PIN                                     SCK  (1)
PIN                                     SO   (3)
PIN                                     SI   (2)
PIN                                     CS   (7)
PIN                                     INT  (5)
VDD                                   VCC  (10)
GND                                   GND  (9)
=================    ===================================

Which pins to use and how to configure them?

Thanks in advance,

Ravi.

Hi,
Well, You can use for example:
P0.03 - SCK
P0.04 - SO
P0.28 - SI
P0.29 - CS
P0.30 - INT

SPI pins are settable in config menu. 
To catch interrupt on P0.30 pin You can use gpio driver. I see that pin can be configured in gpio driver to generate interrupt on particular edge.
There are no dedicated pins for SPI in nRF devices. You can use any of available pins. Of course remember that LED or something else can be connected to the particular pin. Pins suggested by me are safe.
I advise to start with slower clock frequency like 1MHz and increase it when everything will work properly.

Hi Karol,

Thanks for the reply.

SPIM0_NRF52_GPIO_SCK_PIN
SPIM0_NRF52_GPIO_MOSI_PIN
SPIM0_NRF52_GPIO_MISO_PIN
SPIM0_NRF52_GPIO_SS_PIN_0
and for interrupt on gpio, what should I set?

I mean numbers associated with pins
for   e.g. P0.03 - SCK
CONFIG_SPIM0_NRF52_GPIO_SCK_PIN =  3  ?

- Ravi
