enc28j60 connected to nrf52840

[Marques]

Hello, 

I know that maybe you won't be able to help but i'm giving it a try 

I'm trying to use enc28j60 connected to a nrf52840. I saw these example https://gitlab.com/enc28j60driver/enc28j60driver and i'm trying to use this, the IoT SDK and Nordic SDK 17.0.2. I'm using SEGGER.

I'm wondering if there's another way to do it and how. I notice that someone here have done it through uIP and SPI library but it hasn't much information about enc drivers/connection.

Thank you for your attention and time. I really hope you can help me or give me a hint.

Best regards

Catarina

Did you check out the 'Documents' tab?

Might it not be easier to use something like this https://www.wiznet.io/product/tcpip-chip/ - which also embeds the TCP/IP stack?

Hello,

I'm using this kit: https://www.olimex.com/Products/Modules/Ethernet/ENC28J60-H/ it already brings the ethernet adapter to connect to the router/pc (in this case is to connect directly with the pc) :)

Hi,

You may be able to use it through nRF Connect SDK. Zephyr already have support for the through the MikroElektronika ETH Click shield, which looks quite similar to your module. You may need to add some configurations to make the sampleswork with nRF52840 DK and the Ethernet module over SPI, but I assume this should be less work than integrating the driver and IP libraries yourself. Zephyr already also support IP stacks and other protocols required for networking.

Best regards,
Jørgen

I think you may have missed my point?

The point is that the Wiznet devices have the TCP/IP stack built in,  so you don't have to worry about implementing/integrating that - so no worrying about uIP, etc.

They are also available as complete modules: https://www.wiznet.io/product/network-module/

Also as serial-to-ethernet: https://www.wiznet.io/product/serial-to-ethernet/

Other suppliers are also available; eg,

https://www.lantronix.com/products/xport/

https://www.digi.com/products/embedded-systems/system-on-modules/digiconnectme9210

Alternatively, as Jørgen Holmefjord says, you could look at Zephyr & the nRF Connect SDK ...

Note also the 'Related' threads linked by the forum at the bottom of the page ...

We are using a similar setup with enc28j60, nrf52840 and Nordic SDK 17. We managed to make it work almost perfectly by implementing the TCP/IP stack ourselves, but once in a while there are some hard to track issues and we have since shifted into using Zephyr.

Still, it would be great to update a significant amount of devices we have deployed remotely with something that actually works with Nordic SDK 17. Have you found something in the meantime that worked with it?

Cheers,
