Can´t get DT´s interrupts working

Hy guys.

I´m trying to build a little counter to count pulses of varying speed from nil to 120Hz.

YEEES it will be a tripmaster speedo someday.

Tried that with "count" and it works so far, but looses pulses of course and I need every, at least 99,9% of these.

So I tried to get into DTs interrupts and I´m falling on my face (hurts of course)

because I dunno where to start. Tried "Hello World", "Blinky Light", wont do.

So I thought its because of the missing definitions and tried some....wont do

all I get after compiling is the error:
ERROR: Variable wsave3 position request 416 beyond RAM_END 335.

I got Microcode studio 3.0.0.5, picbasic pro 2.50 C

heres my code (stolen from DT of course)

Code:

'**************************************************************** '* Name : ElapsedtimerDT1 * '* Author : Darrel Taylor * '* Notice : Copyright (c) 2010 [select VIEW...EDITOR OPTIONS] * '* : All Rights Reserved * '* Date : 25.04.2010 * '* Version : 1.0 * '* Notes : 16F628A, 4mhz , don´t care about correct timing * '* : * '**************************************************************** '* Date : Jan 10, 2006 * '* Notes : This is a simplistic demo of the Elapsed Timer * '*************************************************************** define LOADER_USED 1 define OSC 4 ' Define LCD connections DEFINE LCD_DREG PORTA ' LCD Data Port DEFINE LCD_DBIT 0 ' Starting Data Bit DEFINE LCD_RSREG PORTA ' Register Select Port DEFINE LCD_RSBIT 4 ' Register Select Bit DEFINE LCD_EREG PORTA ' Enable Port DEFINE LCD_EBIT 5 ' Enable Bit DEFINE LCD_BITS 4 ' Data Bus Size DEFINE LCD_LINES 2 ' Number of Lines on LCD ADCON1 = 7 ' Set portA outputs to Digital / No ADC 'CMCON = 7 LCDOUT $FE,1 ' Initialize LCD PAUSE 200 include "DT_INTS-14.bas" INCLUDE "ReEnterPBP.bas" INCLUDE "Elapsed_INT.bas" ASM INT_LIST macro ; IntSource, Label, Type, ResetFlag?

maybe its about compiler version or something.

any suggestions beyond cry me a river?

the truth is here :

Code:

'*************************************************************************** '* Name : DT_INTS-14.bas * '* Author : Darrel Taylor * '* Version : 1.00 BETA * '* Date : OCT 13, 2009 * '*************************************************************************** '* REV 1.00 Completely re-written, with optimization and F1 chips in mind * '* REV 0.93 Fixed CMIF and EEIF problem with older PIC's * '* that have the Flags in PIR1 instead of PIR2 * '* Rev 0.92 solves a "Missed Interrupt" and * '* banking switching problem * '*************************************************************************** DEFINE DT_INTS_VERSION 100 DEFINE INTHAND INT_ENTRY 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 out wsave1-3 ' --- IF any of these three lines cause an error ?? ---------------------------- ' Comment them out to fix the problem ---- ' -- It depends on which Chip you are using, as to which variables are needed -- 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

so, just comment this line out in your DT_ints.bas file ...

Code:

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

End of trouble ...

now the errors changed

I changed to 16F88 because of the 16bit timer i need later (or now)

now I get those errors:
Error C: \pbp\pbppic14.lib 1160 : [225]undefined symbol 'INT_ENTRY'
Error C: \pbp\pbppic14.lib 1162 : [225]undefined symbol 'INT_ENTRY'
Error : [212] extra tokens on end of line

DT_INTS-14.bas version 1.0

Man where do I get the newest version:

DT_INTS-14.bas version 1.0

????

I get your errors if I do this:

Code:

ASM INT_LIST macro ; IntSource, Label, Type, ResetFlag? INT_Handler TMR1_INT, _ClockCount, PBP, yes endm ;INT_CREATE ; Creates the interrupt processor INT_ENABLE TMR1_INT ; Enable Timer 1 Interrupts ENDASM

got a supersimple DT Timer working

Hi Guys & Dolls,

got the DT program running but needed to implement a stupid LCD comment first!

otherwise the lcd shows only rubbish

Code:

'**************************************************************** * '* Notes : To use this example with MicroCode Studio, you * '* : should: * '* : PIC 16F88 4 MHZ crystal * '* WORKS! ´ * '**************************************************************** CMCON = 7 ' Disable analog comparator ANSEL = %00000000 ' set all to digital Include "modedefs.bas" define OSC 4 ' this example uses a 4MHz clock CMCON = 7 ' RA0-RA3 are digital I/O TRISA = 0 ' PORT A is output TRISB = 3 ' RB0 is Input count RB1 Input reset others output Minute var byte ' Define minute variable Second var byte ' Define second variable Ticks var byte ' Define pieces of seconds variable DoUpdate var byte ' Define variable to indicate update clear ' clear all RAM (sets all VAR declarations to zero) DoUpdate = 1 ' Force first display OPTION_REG = %00000101 ' Set TMR0 configuration INTCON = $A0 ' Enable TMR0 interrupts On Interrupt Goto TickInterrupt PAUSE 100 LCDOUT $FE,1,"Guten" pause 2000 LCDOUT $FE,1,"Tag" pause 2000 ' Main program loop MainLoop: if DoUpdate then LCDOUT $FE,1 LCDOUT $FE,1,DEC2 Minute, ":",DEC2 Second DoUpdate = 0 endif Goto MainLoop ' Interrupt routine to handle each timer tick ' Disable interrupts during interrupt handler disable TickInterrupt: Ticks = Ticks + 1 ' Count pieces of seconds If Ticks < 61 Then ExitInterrupt ' 61 ticks per second ' One second elasped - update time Ticks = 0 Second = Second + 1 If Second >= 60 Then Second = 0 Minute = Minute + 1 If Minute >= 60 Then Minute = 0 endif Endif DoUpdate = 1 ' Set update ExitInterrupt: INTCON.2 = 0 ' Reset timer interrupt flag Resume end

this is a far cry from my goal but at least a big jump for me, an unbelievable small step for mankind, maybe a step back.....

Hey Mulgepower, glad to hear it.

Remember to put your code in brackets like this but without the extra spaces...

[ code]
code goes here
[ /code]

so it is easier to read?

Thanks,

Walter
