Instant Interrupts - Revisited

[ScaleRobotics]

Did you forget these?

INCLUDE "DT_INTS-14.bas"
INCLUDE "ReEnterPBP.bas"

Compiles here as well, but I do get the same errors IF I leave the above lines out of the code. Are you sure the include lines are in your water?

Hi, Ioannis

Compiles fine adding ...

@ __CONFIG  _LVP_OFF & _BODEN_ON & _CP_ALL & _MCLR_OFF & _PWRTE_ON & _WDT_ON & _INTRC_IO

to the top of your code ...

and

'*****************************************************************************
'Includes
'*****************************************************************************

INCLUDE "DT_INTS-14.bas"
INCLUDE "ReEnterPBP.bas"

'-------------   INTERRUPTS SETUP   ---------------------
ASM
INT_LIST  macro;    IntSource,  Label,      Type,  ResetFlag?
    INT_Handler     TMR1_INT,   _timer,     PBP,    yes
    INT_Handler     RBC_INT,    _in_triger, PBP,    yes
    endm
    INT_CREATE            ; Creates the interrupt processor
ENDASM

just BEFORE the Interrupts setup ... ( why ??? good question !!!)

It DIDN'T Compile placed at the top of program ... that's it

- also think to uncomment Wsave, Wsave1 .... etc. in DT INTs listing ....

Alain, there is no problem here where the lines of includes are placed. Either on the very top or just before the macros... Are you sure about that?

Hi,

Yess .. I'm pretty sure !!!

I had an error raising ( Vars_Saved not defined ... but it was correctly defined in the listing ) .

but now I've also uncommented Wsaves and compiler has compiled fine once ... no more compiler errors appears, whatever line the "includes" are placed ...

a bit strange, but not the first strange thing I see with MCS ...

Have tried to compile from command line and it went OK?

I'm looking at a possible necessity to need to upgrade to PIC24's and above...
I use DT INST INT's with my PIC16's and PIC18's however it would be a royal pain to have to write my own interrupt system for PIC24's and above...

Is their any work being done on DT Ints at the moment?
Is their any plans for DT Int's?
Anyone working on DT int's in a team?

Thanks

I have done a lot of work on the PIC24F series using MikroElektronika dsPIC Basic compiler, and have had no issues with Interrupt or having to implement a DT_INT style system. Interrupts are handed well in the compiler, which I think is due to the way the improved architecture handles them. One you try the Peripheral Pin mapping in the 24 series its hard to go back !

The only issue I had was changing my coding style after years of working with PBP ! I still use PBP for all my 16F and 18F stuff, so don't shoot me down for promoting other peoples products !

I used DT-INTS 1.10 on a 16f887

[Ioannis]

When compiling the attached file I get the attached error.

It drives me crazy....

Ioannis

[ScaleRobotics]

Your code compiles here without errors. PBP 2.60A

[Ioannis]

DT-INTS version 1.00 or 1.10?

Ioannis

[ScaleRobotics]

Your code compiles here without errors. PBP 2.60A

To be clearer, your code in post 609 compiles using the code shown. I had not tried it with the IOC_INT, only with the code listed in post 609. I guess you meant that when you changed it to IOC, you got the errors.....

Sorry

[Ioannis]

Thanks all for the support.

Al.: We are testing the new DT-INTs version 1.10. Here as Darrel pointed out the wsave are set in the main program.

Darrel: You are correct in the Port change Interrupts. Ok, I have them corrected and the two errors went away. But no joy on Interrupts. It seems that they are never triggered.

The latest test code is this:

@Line1 = _DEBUG_OFF & _LVP_OFF & _FCMEN_OFF & _IESO_OFF & _BOR_OFF
@Line2 = _CP_OFF & _MCLRE_ON & _PWRTE_ON & _WDT_ON & _XT_OSC

Ioannis,

Remove the second CLEAR statement, and move the GOTO Main after the interrupt declaration, just before the IOC2: handler.

The interrupt declaration and the IOCB/WPUB must be allowed to execute.
