Hi everyone. I'm developing a PWM dimming program using PIC18F4431. There are two LED strings in my circuit. Everything is working except that when the duty cycle of one of the LED strings achieves 10 ...

Thanks for your program.

I'm trying to use a variable resistor to change the duty cycle of the PWM signals. Should I need to change the multiple of the "temp_res" ?

Dear All,

I'm doing a project about PWM Dimming using ADC. I'm using a variable resistor to do ADC but the dimming effect is not obvious. My code is shown as follows.

#include <16F877A.h ...

Dear All,

I'm doing a project about PWM DIMMING using PIC16F877A,

I have two problems.
(1) How can I generate a phase shift between two LED strings?
(2) Following is the code of my project. Ho ...
