I Have a UNO with a TLC5940nt and the ethernet shield.
I've followed the following guide, http://blog.andrewwei.mu/?p=19 The TLC is nearly working with the rewiring, but it won't work unless I keep the TLC connected to However, it is still getting the blank from 10 instead of 8. any one have any ideas as to why? I've tried changing the SS pins in \hardware\arduino\variants\standard\pins_arduino.h. And it does change over and use pin 8, but it still doesn't work unless connected to pin 10 on the arduino.
Moreover, I cannot ping the ethernet unless its connected to pin 10 as well. If it is connected, I can ping it for a few minutes, but then it does eventually stop responding. Additionally, it will never allow me to use the website hosted by the sketch.
The shield and the tlc both work flawlessly when used independently.
I'm stumped now. Any ideas?
