Help with University Project

Hi There

Im very new to assembly code, and I would like to use a simple PIC controller connected to LEDs for a current University product design project, I am able to programme the basics, such as making a flashing led and sequences, but for this project I need help in figuring out how to accomplish my problem. For this project I need to make a set of 8 LEDs brighten and dim (like the 8 Channel PWM LED Chaser) but also to do this in a (perceived) random pattern. any ideas how a beginner at assembly code can achieve this and any pointers of how to go about this? any help or suggestions are greatly welcomed.

Many thanks


Adam

Vertical counters are a little bit hard for a beginner.You need to understand how the PWM takes place.What is PWM, How to do a PWM, What is PWM frequency,Duty cycle & finally must come to how to do a multi channel PWM ........There are many variants done without vertical counters you can find on web.

Ive managed to use basic PWM with 1 LED and get it to switch between 25% and 75% brightness, i would just like to know firstly howto get it fade from 0% upto 100% and back to 0% over a few secs, and i can see on pic projects the led chaser does that but i dont understand how to do it myself
