Hey all,
I've found many old posts on getting the Arduino Ethernet SHIELD to work with the TLC5940 LED Driver Chip, but no results so far on getting it to work on the Ethernet Board.
It seems that for Ethernet Shield + TLC5940, the solution is to change the pinout on the Ethernet Shield from D10 to D8.

However, with the Arduino Ethernet Board, I don't have this option -- the only thing I can do is to change the TLC5940's library.
Is it possible to move the TLC5940's BLANK pin to a pin other than D10? SIN and SCLK look easy enough to change in the tlc_config.h file, but fixing BLANK looks a bit imposing. Has anyone done this before? Does anyone have a modified TLC5940 library for this purpose?
Or is the easiest solution to get an Arduino UNO + Ethernet Shield and then a TLC5940 shield?
thanks,
nathan
