Ok, so, wanting to use a Ethernet Shield with the Arduino Mega 2560.
I would like as many of the 70 inputs/outputs available as possible.
Have been doing some research and am still a little confused…
So, if i use the ICSP header to connect the Ethernet shield, does that interfere with any of the other pins on the Mega2560.
The information that i have read talk about pin 4 and 10 regarding selecting the SD reader and the ethernet. I don’t want to use the SD Card reader.
Can i not connect those two pins and artificially make the (from memory) pin 4 high so it deactivates the SD reader?
I can’t “stack” the shield on top as i already have something that is, so will need to run cables to the ICSP connector on the ethernet shield.
Will that work? or do i need to use some of the pins to communicate?
I hope that makes sense!
Thanks for reading
