Hello,
I want to drive few 7-segment displays using Arduino Yun board and TLC5940 pwm drivers (http://www.ti.com/lit/ds/symlink/tlc5940.pdf). I downloaded tl5940 library for Arduino IDE but if I try basic example it doesn't work. It works only for standard Arduino Uno board but not for Yun (with the same pins connected). I've been searching for library for Yun but I haven't found yet (if it actually exists). Maybe the problém would be in different chips or something...
What could I do to make it run? Thank you for your help 
The TLC5940 is not very suited to driving seven segment displays. Use something like a max7219.
