Wiznet5100 ethernet shield on nRF52840

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.

Frist make sure that the SPI pins are connected correctly. SER_APP_SPIM0_SCK_PIN = P0.27 SER_CON_SPIS_MOSI_PIN = P0.02 SER_CON_SPIS_MISO_PIN = P0.26 SER_APP_SPIM0_SS_PIN = P1.13 There…

Looking at the function wizphy_getphylink() in wizchip_conf.c line 575, it seems that if you have defined the board to be anything else than 5500 or 5200, it will return -1, and you will get the Unknown…
