View source for Hammer How to Enc28j60

First you have to get an [[Enc28j60]], the following links may be usefull:

Next we will be soldering it on to the [[Hammer_Carrier]]

We will use the 3.3V regulator of the [[Hammer_Carrier]], but you already need to have
done the [[Hammer_How_to_Swtching_5V_Regulator]]


Wire the Olimex [[Enc28j60]] board to the [[Hammer_Carrier]] pins as follows:

Also make sure that your 5V main power supply can supply the Hammer as well as the ENC28J60-H.

I used a socket strip that keeps the board about 1/2 inch above the Hammer_Carrier prototype area. This may be important because the PIC chip on the ENC28j60 gets quite warm.

Software driver info:

 The Good  Kernel SPI API
   The Bad  The 2.4 driver
     The Ugly  The current 2.6 "driver" 
       [[Media:enc28j60.c.diff|enc28j60.c.diff]] [[Media:enc28j60.h.diff|enc28j60.h.diff]] [[Media:Kconfig.diff|Kconfig.diff]] [[Media:Makefile.diff|Makefile.diff]] [[Media:map.h.diff|map.h.diff]] [[Media:clock.c.diff|clock.c.diff]]
       [[Media:mach-tct_hammer.c.diff|mach-tct_hammer.c.diff]]


The driver may either be compiled as a module, or as a part of the kernel. 
If you are running short on space for the kernel, it's probably advisable to compile it as module.

The SPI channel that is reserved for the ethernet on the Hammer Carrier board is SPI0.
The MMC interface uses SPI1. The current [[UBE]] driver may need to be re-configured if you are
going to use anything but the Hammer Carrier.
