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

thanks for the reply

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
