I'm using a TLC5940NT to drive multiple LEDs on several channels (40 or so if I remember right). The LEDs are current limited to I will not be using the IREF pin.
However since this is being used in an automotive set up, I'd like to fine tune the brightness of the LEDs via a PWM and I'm not sure how to go about this; any help?
Also is there anyway to avoid the PWM 'flicker' effect when using the TLC5940?
Thanks!
