Instant Interrupts - Revisited

[Darrel Taylor]

Receiving data 1-byte at a time is always the best way to do it with USARTs and interrupts.

No Timeouts, no WAIT(), and no long strings.

For a simple Ring buffer, check out Joe S.'s Serial Backpack program, modified for DT_INTS.

I hope this hasn't been answered already but,

What about using Instant Interrupts with PBPL? Should they work? I'm really hoping I'm just doing something wrong cause I'm gonna need them!! (I'm using Ver 2.50 and 2.60 is in the mail)

Yes they should.

With the PBPL box checked in the compiler options, when I put in your
3 INCLUDE statements:

INCLUDE "DT_INTS-18.bas"
INCLUDE "ReEnterPBP-18.bas"
INCLUDE "Elapsed_INT.bas"

I get a compile error saying:

Error [113] c:\blue1\pbp\pbppi18l.lib 1465: Symbol not previously defined (INT_ENTRY_H)

Does that mean anything to you? No errors without those INCLUDES. No errors if I change to PBP instead of PBPL. (except my LONG variable errors, of course!)

By themselves, the include files will not compile.

There must be an INT_LIST and INT_CREATE in your program.

INCLUDE "DT_INTS-18.bas"
INCLUDE "ReEnterPBP-18.bas"
INCLUDE "Elapsed_INT-18.bas"  ; Elapsed Timer Routines

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

@   INT_ENABLE  TMR1_INT  ; Enable Timer 1 Interrupts

You'll need the -18 version of the Elapsed Timer too.
