Hello,
I have an Arduino with ethershield working, and the same Arduino with an HD44780 display working.
When I put those together on one Arduino, the display doesn't show anything. The ethershield is working fine.
The code only contains a "Hello World" in the display, and an IP address for the ethershield, so it's pingable.
I've read about the pin's the ethershield uses: 10, 11, 12, and 13 (SPI)
Default LiquidCrystal uses pin 11 and 12 also, but I've changed that and tested it separately with success.
Now I'm stuck :-/
Does anybody have the same setup managed to get it working?
Thank you for sharing your sollution P18F4550.
I've also managed now to work both the display and ethernet together.
I also found out (at least I think I did why it was not working for me.
I changed the ports 11 and 12 to unused ports, as the ethernet board uses 10, 11, 12 and 13.
But the problem was in the lower port range.
I can't use port 3 when the ethernet board is connected.
Strange, as it's an original arduino ethershield board and the documentation doesn't mention pin3 being used.
