Change CS pin for ethernet library OR include local library

[tfoutfou]

Hi ,

i have been trying to define the chip select pin for ethernet library for hours and didnt manage to find a way.

Is there any simple way ?

by modifing the definition in w5100.cpp IT WORKS , but i dont want to modify the CS pin for every project of course.

So i tried to include the whole ethernet library folder in my sketch folder

/testsketch/
---- testsketch.ino
------ /src/Ethernet/src/Ethernet.h
------ /src/Ethernet/src/Ethernet.cpp
------ /src/Ethernet/src/Ethernet... and so on

then include

#include "src/Ethernet/src/Ethernet.h"

but at compile the IDE tell me

Using library Ethernet at version 2.0.2 in folder: C:\Users\tfoutfou\Documents\Arduino\libraries\Ethernet

and dont use the one i included manually

How to force IDE to use my copy inside sketch folder ?

Thanks

very simple indeed ...... sometime you put yourself in a rabit hole for no reason

but how would i can include a tweaked version of any library and having the IDE picking the version that i want.

because i would also like to change this line for exemple

#define SPI_ETHERNET_SETTINGS SPISettings(14000000, MSBFIRST, SPI_MODE0)

wich is located at /Ethernet/src/utility/w5100.h

but IDE is picking the version in the main library folder instead of the one included in sketch folder

Thanks

make a copy with a new name

[tfoutfou]

pretty annoying and long , because there is many "define" in almost every file of the ethernet library
with call to each other many time

@tfoutfou

#include "src/Ethernet/src/Ethernet.h"

That second src should not be there.

[tfoutfou]

that's the default structure of the original library folder , moving the files and adjusting the path accordingly dont change anything

in fact , on 20+ installed library , half of them have *.h and *.cpp in a "src" subfolder

[sterretje]

OK, maybe the IDE is more intelligent than I suspected.

I understand that a number of libraries have a 'src' subdirectory. But with normal use of the Ethernet library like #include <Ethernet.h> you do not specify that 'src' directory like #include <Ethernet/src/Ethernet.h>. I might be mistaken though.

just rename the folder name, Ethernet.h and change the include value in library.properties
