How do we write a c code for generating pwm in pic 18f4520?

And perhaps some explanation?

#include<pic.h>
#include<delays.h>

void main()
{
...
...
}

I'm still learning. Thanks.

 

Here is a link to the principle of PWM - http://en.wikipedia.org/wiki/Pulse-width_modulation

 

This is the Code I used on a PIC24FJ128GA010
It's about the most striped down version I can find.

#include <p24FJ128GA010.h> 
_CONFIG1( JTAGEN_OFF & GCP_OFF & GWRP_OFF & FWDTEN_OFF & ICS_PGx2) 
_CONFIG2( FCKSM_CSDCMD & OSCIOFNC_OFF & POSCMOD_XT & FNOSC_PRI) 
void __attribute__((interrupt, no_auto_psv)) _T3Interrupt(void);
void _ISRFAST _T3Interrupt( void){_T3IF = 0;} 
int main() 
{ 
	T3CON = 0x8010;		// This is about 1.25KHz with the Debugger board running at 8MHz 
	PR3 = 400-1;
	_T3IF = 0;
	_T3IE = 1;
	OC1R =OC1RS=200;
	OC1CON = 0x000E;
	while(1);
}

This would produce (on that chip with an 8MHZ Crystal) a 1.25Khz Square Wave (50% modulation)

Here is an english translated version of the link.

It is a very good tutorial.

The only thing that confuses me, is the part where you talk about the two men born to you.. I have yet to figure that out.

There are many types of Bey support this property Take the example is No. 16f877 Bey and the Bey Note that this contains the two men born to me

 

Hi retched,​

hahahaha
I think translation of google not perfect. And also Arabic langauge not like English big difference between them. problem where here ? In Arabic langauge find rules to pronounce any word let's take example​

رَجُل​

This word mean man​

رِجْل​

This word mean leg​

both words have same letters not same in its shapes​

if I wrote this word for you
رجل
and I ask you what is mean this word?
realy you can't know it without its shapes
same problem with google
google don't distingishes shapes of the word​

I hope every thing clear for you​

 

Yes.. I thought the translation was rather funny myself.

 

very fun translation.
legs here mean pins of microcontroller​

and man word there mean legs in electronic mean pins of microcontroller​

Be aware.​

I hope that will help you​

In future I will put English tutorials in my channel
In Matlab, MikroC Pro, Orcad, Proteus and others​

Good. I think you have a lot to offer. And you explain things in a very easy to understand way, with examples and theory.

Ill check out your work.
