tlc5940 blocked? (with arduino)

Other Parts Discussed in Thread: TLC5940

 

Hi people!

I’m trying to control some tlc 5940NT with an arduino using the usual code for this cases.

http://www.arduino.cc/playground/Learning/TLC5940

The problem is that after control a little fading sequence the tlc5940 seems blocked, doesn’t  works and I’ve to wait some time (hours) and then it works again… 

…fascinating.

(or not?)

If someone have curiosity about all the process here is a lot of graphical doc
