Wiznet5100 ethernet shield on nRF52840

[ToasTer86]

Dear Nordic Devzone,

I want to run an Arduino Ethernet Shield with the Wiznet5100 on the nRF52840. I was wondering if there was an easier way to do this then having to rewrite the SPI code by myself.

www.arduino.cc/.../ArduinoEthernetShieldV1

Currently I am using the Keil IAR /uVision to compile my code and can easily compile and run all the examples included. I am just a bit lost on how to use the ethernet shield with the nRF52840.

I thought I would be able to use some Arduino library to easily get it working.

Any help or direction in which to start would be much appreciated.

Hi,

You can find a nRF5x SPI library for the WIZnet 5500 chip at this github page. This should be a good starting point.

Also see this blog post about WIZnet's BLE to TCP Gateway.

Found this image of the wiz5100 ether net shield link text

Using this layout I changed the pins to correspond to that layout:

#define ARDUINO_13_PIN              NRF_GPIO_PIN_MAP(1, 15)  // Digital pin 13
#define ARDUINO_12_PIN              NRF_GPIO_PIN_MAP(1, 14)  // Digital pin 12
#define ARDUINO_11_PIN              NRF_GPIO_PIN_MAP(1, 13)  // Digital pin 11
#define ARDUINO_10_PIN              NRF_GPIO_PIN_MAP(1, 12)  // Digital pin 10

                        .Pin_SCK                = ARDUINO_13_PIN,
                        .Pin_MOSI               = ARDUINO_11_PIN,
                        .Pin_MISO               = ARDUINO_12_PIN,
                        .Pin_CSN                = ARDUINO_10_PIN};	

now the print out of my terminal has changed, to :
