Ethernet Gateway on Arduino nano

[MrTomtom]

Hi

i try to compile the ethernet gateway sketch for an adruino nano with a ENC28J60 module. I get the error:
Sketch uses 33,370 bytes (108%) of program storage space. Maximum is 30,720 bytes.
Global variables use 1,672 bytes (81%) of dynamic memory, leaving 376 bytes for local variables. Maximum is 2,048 bytes.
....
Sketch too big

I have comment out the lines as described in the begin of the sketch:

//#include <DigitalIO.h>     // This include can be removed when using UIPEthernet module  
// Use this if you have attached a Ethernet ENC28J60 shields  
#include <UIPEthernet.h>  

// Use this for WizNET W5100 module and Arduino Ethernet Shield 
// #include <Ethernet.h>  

and also comment out the DEBUG in the MyConfig.h file:

// #define DEBUG

I use the arduino 1.6.5 on Windows 7.

Thanks for your support.

Regards
Thomas

Hi,

i am new to mysensors, and i have an another Problem, but i have an Arduino Nano and when i compile the Sketch it shows that this use 95%. So it dows work for me.
I hope its usefull for you.
Maybe you have some libriaries which will be comiled in to arduino. Try to load only MySensors libs in Arduino Programm.

@MrTomtom said:

ENC28J60

Code footprint for ENC28J60 is significantly larger than for W5100.
Any chance you can use a W5100 for the gateway?

[MrTomtom]

@meddie: did you use also an ENC28J60 for lan-connection? or an W5100?

@Yveaux: yes, the chance is real. I can order a lan-shield with W5100. But i could not believer that it's not possible to compile the gateway with an ENC28J60... And the ENC28J60 looks nicer with the arduino, so i get a small package with lan-shield, arduino and rf-shield.

Anyone had compile successfull the lan-gateway wtih ENC28J60?

Hi yes i have an enc and I can compile. 95% used.

[MrTomtom]

Strange.... on which platform do you compile? Windows, Linux? and which version do you use of arduino ide?

[meddie]

Hi,
on Windows 7 arduino IDE 1.6.6.
I have to use win 7 because i use a Clone of arduino nano and this have a prolific 2303 Chip wich Has only drivers for win 7.

@MrTomtom @meddie Which MySensors library are you using?

[meddie]

the newest 1.5.1

Remark out as many serial statements as you can.
With any luck you can scrape a few bytes back and it will compile and run.

Even if you have some form of debug define set for serial output the serial statements are still viable memory hogs.

MySensors 1.6 (still in development) is quite a lot smaller than 1.5. You cound try it and see if it is enough.
