Running 8OD with the Arduino ethernet shield


The ethernet shield was always on my list of things run with 8OD, but sat in the “too hard” basket, mostly because I was afraid of a difficult software task, which in the end would turn out to be rather simple.

  1. I had a similar conflict on the spi bus early on with an SD card. I found it wouldn’t release MISO even when it was deselected. I dealt with it on the olduino board by putting a 1K resistor between the arduino’s MOSI header and my internals. This was important because the 1802 Olduino also needs functioning SPI to boot. I think this was before the ethernet card so i never noticed the problem there.
