assembly error on DT interrupts

[HenrikOlsson]

Hello,
This "DT_INTS-18-k80.bas" and the matching re-enter file, did you download them from somewhere or are you trying to customize the default ones yourself?

I don't have those files and a simple search did not find them so I can't test much here except compiling a bare bones example with the standard DT-Ints-18 files and, needless to say, it compiles and assembles without errors.

If you try the above with the stock DT-Ints files, does it compile? If you try with your K80-version of the DT-Ints files, does it compile?

Hello Henrik,

I tried to compile the original DT Interrupt file linked from the DT Interrupts tab above. It generated the same error as I listed in my first post. It says that the "INTHAND" was not previously defined. As you can see from the code listed on the DT Interrupts page, INTHAND was defined. It is not a processor problem because it reproduces with different processors. I am using the PIC18F46K80. It does not complain about the INTLHAN definition so I don't know what is going on here. I removed all my files and tried to compile just the original DT interrupts and got the same error.

Thanks,

Paul

Something is wrong here... It sounds like you're trying to compile the DT-Ints file by itself, is that the case? If so, just stop doing that. They're not meant to compile by themself, they must be "fed" with information from the program in which they are used, namely the names of entry point for various interrupts, ie the INT_LIST macro (the part shown below).

No, that's not what you're doing. OK, moving on...

Like I said in my previous post, the code I posted does compile for the K80 using the stock DT-Ints-18 files.
If you look closely the DEFINE USE_LOWPRIORITY is commented so not in play (same in your code above). If I uncomment that line I get Symbol not previously defined (INT_ENTRY_L) because I'm telling DT-Ints that I want to use low priority interrupts but have none defined.

Then, if I remove the whole interrupt declaration part, ie

ASM
INT_LIST  macro    ; IntSource,    Label,      Type, ResetFlag?
        INT_Handler   TMR1_INT,  _ClockCount,   PBP,  yes  ;-- Timer Int.
        INT_Handler   INT0_INT,  _MoveCmd,      PBP,  yes  ;-- Flap Switch
   endm
    INT_CREATE          ; Creates High Priority interrupt processor
ENDASM

I get both Symbol not previously defined (INT_ENTRY_L) and Symbol not previously defined (INT_ENTRY_H), again because I've now not told DT-Ints which interrupt handlers I want "connected" with what interrupts.
