I have a Arduino Mega + Ethernet Shield with the 4pin Hack, see: http://mcukits.com/2009/04/06/arduino-ethernet-shield-mega-hack/
I want to upgrade my 8bit PWM outputs to 12 bit PWM's using Texas Instruments TLC5940 IC http://www.arduino.cc/playground/Learning/TLC5940
For this to work Digital I/O pins 3, 9, 10, 11, 13 need to be used. Normally not a problem but the Ethernet Shield hack has moved the pins 13, 12, 11 and 10 to the pins 50,51,52,53. Does this mean I have to connect the TLC5940 to these new pins (50,51,52,53) or to the old pins (10,11,13).
I am not sure on how to proceed and am afraid to blow up the Arduino without some advise / confirmation.
