TLC5940 & 2560

Hi,
Trying to get a TLC4950 and 4 RGB LEDs working with a Mega 2560.

Had it working on Diecimilia previously based on playground article & wiring diagram.
I am changing the wiring to this for the MEGA.
TLC59040 MEGA
26 SIN ------------ Pin 51
25 SCLK 25 -------- Pin 52
24 XLAT ----------- Pin 11
23 BLANK ---------- Pin 12
18 GSCLK ---------- Pin 9

Based on this: Google Code Archive - Long-term storage for Google Code Project Hosting.
Is this the correct setup for the MEGA 2560?
Also, What is a quick way to check if the 5950 chip is fried or I damaged it?

Thanks.

Put it back on the Diecimilia?

Why not use the same pins as you used on the Diecimilia?

Ok, tried putting it back on the Diecimilia and it works fine.
I'm using different pins because it won't work at all if I wire the MEGA at like the Diecimillia.

I was off by one wire.

This wiring now works on the MEGA 2560.
