Atmega4808 + Enc28j60 Ethernet compile Error

josephchrzempiec · October 23, 2021, 8:40am

Hello I know the atmega4808 is still kind of new to arduino. but I ran into a little compiling error.

It says there is a incompatable with the 4808 for the enc 28j60 library. below I'm attaching the example code and error of which came up. I'm unsure what to do or how to fix this. Can someone please help me?

That is not little, it needs a rewrite to work. Just use an ATMEGA328! It will save all the issues you are having.

Juraj · October 23, 2021, 9:45am

I recommend my EthernetENC library which has the standard Arduino Ethernet API and compiles on 4809

josephchrzempiec · October 23, 2021, 10:08am

I do not have any 328. But I currently only have these 4808.

josephchrzempiec · October 23, 2021, 10:10am

Hey Juraj do you have a link? Currently I’m not at my desk. Or do you have a link for your whole libraries please?

I downloaded your library and there is no Example ones that I can find and test. Do I need to change something on mine to go to your library? I did change it to the 4809 from the 4808 in the board selection.

hello, I did change out what it is needed and I get new error message. I'll post the original code and the new code with the library change.

I'm not sure what would be the next step. I'm just running a simple web server and it looks like From that page #8 says to only change #include <EtherCard.h> to #include <EthernetENC.h>. Is there any other thing I needed to change?

Hi,

Don't you have a UNO or Nano?

Tom...

josephchrzempiec · October 24, 2021, 12:42am

Hello Tom, No not at the moment I lend it to a friend of mine my uno board about 200 miles away. I don't think I will get it back anytime soon lol

josephchrzempiec · October 24, 2021, 12:46am

I think i read the website a little wrong. It looks like I'm suppose to use the ethernet example not the etherCard example. Let me try that.

the ethercard library has a not standard API. the EthernetENC library has the same API as the Arduino Ethernet library.
