EtherCard does not work on Arduino Due, compilation error

[jrrsoftware]

Hi,
I have a compilation error on my Arduino Due:
C:\Users\Jacek\Documents\Arduino\libraries\ethercard-master\dhcp.cpp: In static member function 'static bool EtherCard::dhcpSetup(const char*, bool)': C:\Users\Jacek\Documents\Arduino\libraries\ethercard-master\dhcp.cpp:327:61: error: 'strncpy_P' was not declared in this scope strncpy_P(hostname, hname, DHCP_HOSTNAME_MAX_LEN); ^ Error compiling.

there is no other code in my sketch, just the library include:

#include <EtherCard.h>

void setup() {
}
void loop() {
}

I'm getting more compile errors, whe trying to add the EtherCard libarary from Arduino IDE (using all 3 header files):

#include <enc28j60.h>
#include <EtherCard.h>
#include <net.h>

void setup() {
}

void loop() {
}

What I'm doing wrong?
Thanks for help

Hi Jack

I had the same issue when i started using the enc28j60

Your problem is a clash between the two libraries enc28j60 & EtherCard

You can't use both, Pick one to use. Also I think that the version of the IDE also has a part to play, but can't remember which one to use.

also this is a duplicate issue of #192

Hope this helps

Hi,
I tried different combinations of includes. If just one is used:

#include <EtherCard.h>

void setup() {
}

void loop() {
}

Another compilation error is shown:

C:\Users\Jacek\Documents\Arduino\libraries\ethercard-master\dhcp.cpp: In static member function 'static bool EtherCard::dhcpSetup(const char*, bool)':
C:\Users\Jacek\Documents\Arduino\libraries\ethercard-master\dhcp.cpp:327:61: error: 'strncpy_P' was not declared in this scope
             strncpy_P(hostname, hname, DHCP_HOSTNAME_MAX_LEN);
                                                             ^
Error compiling.

I don't know where the strncpy_P function is declared. Anyway, I commented it in the library (just for test) and got another compilation error:

Any ideas?

P.S.: I use latest version of Arduino IDE (1.7.8) if that matters.

[Daniel-dk]

The errors you get (" error: 'SPCR' was not declared in this scope ") are because the Ethercard library uses AVR SPI registers directly and not the Arduino SPI library,
the registers and usage of AVR is not compatible with ARM.

You might be able to go trough the "hardware interface " where specific AVR SPI registers are used and replace them with SPI library functions.

• a simple example is sending data :
  SPDR = *data++;
  can become
  SPI.transfer(*data++);

you will still need to set up the SPI port etc..

[solarkennedy]

I could update the docs to make it explicit that this library only supports AVR-based platforms?

[Daniel-dk]

That would probably solve some misconcptions.
I might have to take on porting this to be compatible with the arduino Zero at some point - if we take on a specific project that allows me to spend time on it and requires a cheap-ish Ethernet interface - thats a rabbithole for another time

[solarkennedy]

Ok. I'm ok with closing this one as "not supported" (yet). This library predates the arduino SPI library. I don't think a port would be that hard, but as @Daniel-dk says, you kinda need a reason to go down that rabbit-hole.

[njh]

Slightly closer to making EtherCard run on non-AVR micro-controllers.

I have created Pull Request #335 for switching to using the Arduino SPI library. Needs a little bit more work but it is nearly there.

If anyone is able to help with testing, that would be great.
