Hammer How to Enc28j60

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


 * SparkFun
 * Olimex
 * MicroChip
 * uC Pro's

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_Switching_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" included in the kernel patch at Hammer_Board_Software

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.
