Pwm portb in pic 16f628 in same time

Can anybody tell me, is possible to write some program in Pic Basic,to
PWM ALL PORTB, IN PIC 16F628 IN SAME TIME !!!
I thing to all PORTB.0,PORTB.1,PORTB.2,PORTB.3,PORTB.4,PORTB.5,PO RTB.6,
fade in SAME TIME,TOGETHER ALL PORTS,GO 0-100%,
and SAME TIME, go 100%-0 !!!
ANY HELP,IS GOOD FOR ME!!!

Re: Pwm portb in pic 16f628 in same time

The output of the hardware PWM module in the 16F628A is on PORTB.3. Hence this the only pin you can use for the PWM output.
Do you need exactly the same signal on 8 pins? If so, you can just take multiple connections from the same pin (PORTB.3).
If you need 8 Different PWM signals, you could use a software interrupt based routine.
You can have a look at Darrel's Multiple Software PWM.
http://www.darreltaylor.com/DT_INTS-14/SPWM.html
He has included a very nice description on how to use it.

Thks.so much!
yes, I need 8 Different PWM signals!!!
I looking this site,I found code for PWM,
but when I tried COMPILE,
I have so many errors,I dont now what is happed!!
Code is:

Code:

and to many errors

Re: Pwm portb in pic 16f628 in same time

And I tried,compile in PicBasic,this code:

Code:

define OSC 20 define SPWMFREQ 100 ' PWM frequency in Hz DutyCycle1 VAR byte ' 0-255 0=Idle Low 255=Idle High DutyCycle2 VAR byte DutyCycle3 VAR byte SPWM1PIN VAR PORTB.0 ' SPWM channel 1 define SPWM1VAR _DutyCycle1 SPWM2PIN VAR PORTB.1 ' SPWM channel 2 define SPWM2VAR _DutyCycle2 SPWM3PIN VAR PORTB.2 ' SPWM channel 3 define SPWM3VAR _DutyCycle3 Include "Multi_SPWM.pbp" DutyCycle1 = 0 DutyCycle2 = 127 DutyCycle3 = 255 Loop: Pause 100 Goto Loop

and I have errors:

Code:

ERROR: Variable wsave3 position request 416 beyond RAM_END 335.

Can anybody now what is problem!!!:(

Re: Pwm portb in pic 16f628 in same time

Hello,

Your code from post # 3 compiles fine over here.

For your wsave error, you have to open the DT_INTS14 file and follow it's instructions:

Code:

' --- IF any of these three lines cause an error ?? ------------------------ ' Comment them out to fix the problem ---- ' -- Which variables are needed, depends on the Chip you are using -- wsave1 VAR BYTE $A0 SYSTEM ' location for W if in bank1 wsave2 VAR BYTE $120 SYSTEM ' location for W if in bank2 wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3 ' --------------------------------------------------------------------------

I like use this,for PIC 16f628,and I dont now how compile,in PicBasic,all time I have errors!

Re: Pwm portb in pic 16f628 in same time

In your code for in post 4, where did you get

Multi_SPWM.pbp ?

Edit: I deleted the bad advice

Re: Pwm portb in pic 16f628 in same time

I get this code in this site:
http://www.darreltaylor.com/DT_INTS-14/SPWM.html

Re: Pwm portb in pic 16f628 in same time

Perhaps I am missing something.

The code you show in post # 4 has no DT_INTS include file. It does have an include file named Multi_SPWM.pbp , which I gather is really SPWM_INT.BAS from this link: http://www.darreltaylor.com/DT_INTS-14/SPWM_INT.bas.txt .

If this is correct, then you should have an include in your file for DT_INTS, really I think that is the only way to get a WSAVE error, but I could be wrong.

Your might try something more along the lines of the example code, here: http://www.darreltaylor.com/DT_INTS-14/SPWM.html with both include files, etc. If you get a wsave error, make sure you are editing the right DT_INTS_14.bas file, whatever you call it in your include statement.

For your chip, it should be edited so that:

Code:

' --- IF any of these three lines cause an error ?? ------------------------ ' Comment them out to fix the problem ---- ' -- Which variables are needed, depends on the Chip you are using -- wsave1 VAR BYTE $A0 SYSTEM ' location for W if in bank1 wsave2 VAR BYTE $120 SYSTEM ' location for W if in bank2 ;wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3 ' --------------------------------------------------------------------------

EDIT: A little late, but I found where Multi_SPWM.pbp came from http://www.pbpgroup.com/modules/wfse...p?articleid=12

Re: Pwm portb in pic 16f628 in same time

Yes,I have DT_INTS_14.bas file,I write correct name.
I do what you tell me,but now I have errors.
If I understudy you,i MUST WRITE THAT,CODE?

' --- IF any of these three lines cause an error ?? ------------------------
' Comment them out to fix the problem ----
' -- Which variables are needed, depends on the Chip you are using --
wsave1 VAR BYTE $A0 SYSTEM ' location for W if in bank1
wsave2 VAR BYTE $120 SYSTEM ' location for W if in bank2
;wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3

' --------------------------------------------------------------------------

I do that but I have errors when I compile.

This program in my PicBasic :

is correct?

Re: Pwm portb in pic 16f628 in same time

Sorry, you are correct, you just need the wsave at $70. If you are going to put it in your file, just make sure they are all edited out in the include file. But put:

wsave VAR BYTE $70 SYSTEM ' location for W if in bank0

above the include line.

Sorry for giving you bad advice.

Re: Pwm portb in pic 16f628 in same time

Ic,ok I am not professional in PicBasic, I learning,but thks,to your help!

Is correct this :

Code:

;-- Place a copy of these variables in your Main program ------------------- ;-- The compiler will tell you which lines to un-comment -- ;-- Do Not un-comment these lines -- ;--------------------------------------------------------------------------- ;wsave VAR BYTE $20 SYSTEM ' location for W if in bank0 ;wsave VAR BYTE $70 SYSTEM ' alternate save location for W ' if using $70, comment wsave1-3 ' --- IF any of these three lines cause an error ?? ------------------------ ' Comment them out to fix the problem ---- ' -- Which variables are needed, depends on the Chip you are using -- wsave VAR BYTE $70 SYSTEM ' location for W if in bank0 ;wsave1 VAR BYTE $A0 SYSTEM ' location for W if in bank1 ;wsave2 VAR BYTE $120 SYSTEM ' location for W if in bank2 ;wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3 ' --------------------------------------------------------------------------

I write now this in my file DT_INTS-14.bas
but now I have error message :

Code:

ERROR Line 50: Redefinition of VAR.

I dont now what is now???:confused:

Re: Pwm portb in pic 16f628 in same time

That means you have this line in two places, like in your code, as well as they include file:

wsave VAR BYTE $70 SYSTEM ' location for W if in bank0

You can have it in either, but not both.

Re: Pwm portb in pic 16f628 in same time

ok,and what i must do, to fix my problem?

Re: Pwm portb in pic 16f628 in same time

Can you ask you for this code,why i cant compile this code?
What is wrong?

Code:

Edit it out of your include file, and I would not have it in your Main. I would move it above your include statement like this:

Code:

What error do you get?

Re: Pwm portb in pic 16f628 in same time

I get this error.

Code:

ERROR: Variable wsave3 position request 416 beyond RAM_END 335.

Somewhere in your include file, mysteriously named "Multi_SPWM.pbp" is a DT_INTS file that still has

wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3

and it is not commented out.

Re: Pwm portb in pic 16f628 in same time

I think that May 16, 2004 code (pretty old) came before DT_INTS. I still don't know where you found it. Your error is from all the wsaves in the Multi_SPWM.pbp include file. So simply edit them to be:

Code:

;wsave var byte $20 SYSTEM ' location for W if in bank0 wsave var byte $70 SYSTEM ' location for W if in bank0 ' --- IF any of these three lines cause an error ?? 'Simply Comment them out to fix the problem ---- ;wsave1 var byte $A0 SYSTEM ' location for W if in bank1 ;wsave2 var byte $120 SYSTEM ' location for W if in bank2 ;wsave3 var byte $1A0 SYSTEM ' location for W if in bank3 ' ------------------------------------------------------------------------------

if you are not going to specify it in your code.

Re: Pwm portb in pic 16f628 in same time

Ok,I try this code some time to fix,thks allot,for your help!!!! http://www.picbasic.co.uk/forum/imag...lies/smile.gif
Just one question
can you tell me, because I like learn Pic Basic ,where I can find some nice tutorial or some video tutorial,about Pic Basic,to I learn write code in Pic Basic,and where i can find some expansion,for how i write code in Pic Basic!

Re: Pwm portb in pic 16f628 in same time
