Maybe could be a bad PIC configuration settings?

Shouldn't first go? TRISA = 255; and then PORTA = 255; Instead of: PORTA = 255; TRISA = 255; Heyy, maybe it is PWM1_Init ? Maybe it should be changed? I am using 4MHz external quartz crystal oscillator (XT). void PWM1_Init(const long freq); Initializes the PWM module with duty ratio 0. Parameter fre...

OK, that would be great.

Hello, thank you, I will try it.

How the program worked for you? What has been changing, when you each time pressed those buttons? Did the brightness increased very slow, or you need to press a button and wait for some time to increase brightness...?

So why the program isn't working?

What should do RA0-RA3 buttons? What should they change?

The program is Proteus 7 Professional, and it let to simulate a whole schematic, as it would be in reality

I tried many other circuits with 10k resistor, and everything worked..

What means if (RA0_bit) ?
What logic state should go to PIC, when button is pressed?

There is no voltage on output pins at all...

Hello, I am using PIC16F887 and this schematic:

Hello, how button presses should be counted?

Hello, i am trying to use Your program example of PWM usage: unsigned short current_duty, old_duty, current_duty1, old_duty1; void InitMain() { ANSEL = 0; // Configure AN pins as digital ANSELH = 0; C1ON_bit = 0; // Disable comparators C2ON_bit = 0; PORTA = 255; TRISA = 255; // configure PORTA pins ...

Hello, is there any way to make an LCD menu changes when using buttons?
How a program should look like, if I want, for example: when I press a button, an LCD writes a word, when I press THE SAME button again - an LCD writes another word. Thank you.

I had the same problem, and logged in only when changed a password from "Forgot the password...".

Why there is so many protections, like captha, post approval...?

Hello, EXAMPLE 10 Module CCP1 as PWM signal generator program from http://www.mikroe.com/eng/chapters/view/12/appendix-b-examples/ simulated in Proteus and it does not work (no signal to LED), there is no change by pressing buttons. What am I missing, or just all of those programs are with 'secret' ...

Thank you, I really forgot about those general purpose registers. I changed them and now the program works as it should be
