I'm familiar with the TLC5940. Interfacing the LED's to the TLC5940 is easy: you simply put one of the channels of the TLC5940 between the LED and ground.
Of course, getting the TCL5940 to actually control the brightness of the LED is substantially more involved by comparison. However, in order to provide any assistance beyond what is explained in the datahseet, we'll need to know a bit more about what specifically your troubles are.
Thank you very much for your replay and Very Sorry for my delay replaying.
dear keso! I'm familiar with mikroc and Mikrobasic Language and im new to electronics .Actually my requirement is to build a LED Runner circuit just like (YouTube - Arduino Controlling a TLC5940 To Fade LEDs) with PWM fading effect. I went through TLC5940 datasheet but I couldn't understand followings
