I recently bought an ENC 28J60 module from geeetech<\/a>. They offered a download for drivers and examples for arduino, but it turned out there were two grave snags:<\/p>\n

My debian system had gcc-avr v 4.7.x, there are some resent changes that means that some of the arduino code does not compile. I was told that:<\/p>\n

\/usr\/share\/arduino\/libraries\/EtherCard\/tcpip.cpp:459:20: error: variable 'c' must be const in order to be put into read-only section by means of '__attribute__((progmem))'<\/code><\/p>\n

I don’t care if it is an error in the compiler or in the arduino system (as it was discussed on some lists), to get it to work, I just downgraded the compiler to version 4.3.5-1<\/a> (if you are using another system, you must download it from somewhere else). Then I installed it with sudo dpkg –install <package>. avr-libc should be dowgraded to 1.6.8<\/a> (the compiler worked without downgrading the libc, but that made further upgrades of the system impossible). To make those downgrades survive later system upgrades, pin them in \/etc\/apt\/preferences.d\/avr which should contain<\/p>\n


\nPackage: avr-libc
\nPin: version 1.6.8*
\nPin-Priority: 1001<\/p>\n

Package: gcc-avr
\nPin: version 4.3.5*
\nPin-Priority: 1001<\/p>\n

<\/code><\/p>\n

It also turned out that the code from geeetech was pre v 1.0 of the arduino SDK. Editing some code and adding in the WConstants.h and wiring.c and wiring.h from v 0.23 of the arduino SDK, i got it all to work (at least so far).<\/p>\n

My working library can be found here : ENC28J60.tar<\/a> (132k) (git repo so my changes can be seen)<\/p>\n

This works fine with the examples where the arduino acts as a server. I have still not managed to get it to work as a client.<\/p>\n

I am now connecting the 28J60 to the arduino using a ribbon cable (Split an old floppy disk cable to have just 10 conductors) The connections will then be:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
