Instant Interrupts - Revisited

[Homerclese]

Hello,


I have been toying with Darrels' interrupts and the elapsed timer

programs. It's an amazing piece of work and just what I need at the

moment. Thanks!

Going on, I tried the "bring together" demo but that didn't go so

well. It won't compile using MPASM. The error messages are ;


FATAL ERROR too many errors
Error line 15: redefination of VAR. (DT_INTS-14.bas)
Error line 26: redefination of VAR. (DT_INTS-14.bas)
Error line 27: redefination of VAR. (DT_INTS-14.bas)


........Etc.


I am using the Pic 16f877 but that shouldnt matter at this point.

Any ideas?

Thanks John

mmm, weird, no problem here. so we talk about
http://darreltaylor.com/DT_INTS-14/combine.html

If so, did you add something special in the code or you're using EXACTLY the following...

LED1   VAR  PORTD.0
LED2   VAR  PORTD.1

INCLUDE "DT_INTS-14.bas"     ' Base Interrupt System
INCLUDE "ReEnterPBP.bas"     ' Include if using PBP interrupts
INCLUDE "Elapsed_INT.bas"    ' Elapsed Timer Routines

ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler    INT_INT,  _ToggleLED1,   PBP,  yes
        INT_Handler   TMR0_INT,  _ToggleLED2,   PBP,  yes
        INT_Handler   TMR1_INT,  _ClockCount,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

OPTION_REG = OPTION_REG & $80 | 1  ; Set TMR0 Prescaler to 256, leave RBPU alone
@    INT_ENABLE   INT_INT     ; enable external (INT) interrupts
@    INT_ENABLE  TMR0_INT     ; enable Timer 0 interrupts
@    INT_ENABLE  TMR1_INT     ; Enable Timer 1 Interrupts  

GOSUB ResetTime              ' Reset Time to  0d-00:00:00.00
GOSUB StartTimer             ' Start the Elapsed Timer

Main:
    IF SecondsChanged = 1 THEN  
       SecondsChanged = 0
       LCDOUT $FE,$C0, DEC Days,"d-",DEC2 Hours,":",DEC2 Minutes,":",DEC2 Seconds
    ENDIF
GOTO Main

'---[INT - interrupt handler]---------------------------------------------------
ToggleLED1:
     TOGGLE LED1
@ INT_RETURN

'---[TMR0 - interrupt handler]-------------------------------(Blinky Light)------
T0Count  VAR WORD
ToggleLED2:
    T0Count = T0Count + 1
    IF T0Count = 512 THEN T0Count = 0 : TOGGLE LED2
@ INT_RETURN

which version of PBP and MPASM are you using?

Are all files located in the same folder?

[Homerclese]

Hello,

I tried a cut and paste of your code and got a whole new set of errors. The only code differences I could find were the ones at the top for outputting to a LCD display. The include files all exist in my usual PBP folder. I'm using Microcode Studio version 2.2.1.1 with Pic Basic Pro 2.40.


Thanks John

[mister_e]

did you get...

<img SRC="http://www.picbasic.co.uk/forum/attachment.php?attachmentid=1438&stc=1&d=117284877 8">

If so, make sure you have selected MPASM in the View>> Compile And Program option >>> Assembler

EDIT

Pic Basic Pro 2.40.

I don't know if it could be the problem... The current version is now 2.47.

Gettin' better!

MPASM box was not checked. I didn't know it existed. No errors on compile now, however it can not find the .HEX file for programming. I did a system search and there is no .HEX file generated after compile. There are .HXH and .HXL files.

Is your result box a screen capture?

Thanks again

[mister_e]

It happen because you probably have selected INH8XS file format under the MPASM check box. use INHX8M instead.

Is your result box a screen capture?

Yes indeed, CTRL + PrintScr, then you paste it in Paint or whatever else to edit it.

[Homerclese]

Good, That worked. However, when I add a line to the top of the program as simple as :
TRISA = %00000000
AlarmOUT VAR PORTA.0

I get

Error[113 cbp\pbpic14.lib 1588 : Symbol not previously defined (port A)
Error[113 cbp\pbpic14.lib 1612 : Symbol not previously defined (port A)
Error[113 cbp\pbpic14.lib 1619 : Symbol not previously defined (port A)

.........Etc.


Also, going back to the previously working "elapsed timer demo" and using the MPASM settings I get the same type of errors there if I try to add a port reference.

I can get the result box into Photoshop but can't get the edited image to paste into the forum.


Thanks
