Hello,

I successfully compiled the following prg but but couldn't run it. Do you think I should include the config bits?

#include <18f452.h>
#FUSES XT,NOWDT,NOPROTECT,NOLVP,NOPUT,NO ...

Sorry, I posted the wrong code. Here comes the actual code:

#include <18F452.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)

unsigned char FlagReg; ...

Hello,

For the following code, I got some errors:

#include <18F452.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)

unsigned char FlagReg;

Thank you all for your detailed answers.

Hi Everybody,

I'm trying to achieve tri-phase angle control of a thyristor using PWM on 18F452. I know the code for single phase, but how can we implement in three phase? I'm restricted to use 18 ...

Unfortunately my boss insists I do this way. You can understand my level from overseas but he can't even tho he is here. We'll see how it goes.

Will it be enough if I just clock shift register or do I have to control both shift register and ULN?

Here comes schematics. The PIC and RELAY are connected to each ther via big black arrows shown in the images. I think I didn't write any code for the register CD 4094. Might this be the reason why ...

Is there a way in this forum to post schematic?

The thing is that when I power the relay board, the leds turn on like a lamp, but no blinking meanwhile.

Yes, it does compile but no led flashes.

Hello,

Could you maybe check my following ccs c code used to control a relay driver for turning on/off leds. Unfortunately does not work.

#include <18F452.h>
#define Fosc 16000000 //Bau ...
