Resurrecting this thread !
I am trying to achieve something similar : scrolling messages that are retrieved from a remote server on a 32x16 LED matrix
I am using an Arduino Uno (R3) + an Ethernet shield (W5200).
I managed to retrieve information from the remote server. (Ethernet OK)
I managed to display serial input on the LED matrix (Matrix OK)
... but never managed to display information that is retrieved from the server on the matrix (Ethernet + Matrix not OK)
As soon as matrix.begin is called, the program seems to hang.
Stumbling upon the above post from pburgess :
Oh! Ethernet! Heck yeah, that library's going to require a TON of RAM. No way to do the 32x32 matrix and Ethernet together on an Uno.
... I am getting a bit pessimistic.
Could anyone confirm that I can give up trying to make this work (pburgess statement still holds true)?
What would be the best bet ? Buying a Mega ? a Pi ?
Thanks a lot !
