Hopefully, more info and examples forthcoming.

Very cool! I've got to try these out. Thanks Alexander and Darrel!

As always, a great Darrel Taylor's project!

Thanks!

Wow, this is going to be very cool Darrel!
I know you said to keep trying if it wouldn't compile but I can't seem to get it to "go thru" when using it in the same program as DT-Ints... Boiled down example, this compiles:

PRECISION CON 4 SYSTEM
INCLUDE "N-Bit_Math.pbp"

Setpoint VAR BYTE[PRECISION]
Position VAR BYTE[PRECISION]
Error VAR BYTE[PRECISION]

Start:
Pause 10
Goto Start

This does not compile (or assemble):

PRECISION CON 4 SYSTEM
INCLUDE "N-Bit_Math.pbp"
INCLUDE "DT_INTS-18.pbp"             'Include the interrupt system files.
INCLUDE "ReEnterPBP-18.pbp"

ASM
INT_LIST    macro   ;IntSource    Label   Type   ResetFlag
       INT_Handler INT2_INT,    _DoStep,   PBP,     yes                                
            endm
    INT_CREATE
ENDASM

@ INT_ENABLE INT2_INT

Setpoint VAR BYTE[PRECISION]
Position VAR BYTE[PRECISION]
Error VAR BYTE[PRECISION]

Start:
Pause 10
Goto Start

DoStep:
Toggle PortB.7
@ INT_RETURN

I get a whole bunch of Symbol not previously defined FSR0L0L and so on.

Similarily, same code as above but simply removing the INCLUDE "N-Bit_Math.pbp"-line also compiles fine so there seems to be some incompatibillity there.I'm using 18F2431 but the device selected in MCS+ doesn't seem to matter.

Any ideas what might be the issue?
Thanks!

Hmmm, apparently it's laughing at my use of FSR's "FSR0L0L".

You are correct, there is a conflict when used with DT_INTS-18.
DT-INTS-14 is OK.

I must find a way around it.

Thanks Henrik.

[Darrel Taylor]

Thanks again Henrick.
The FSR problem should be fixed.

The file has been updated to version 1.1 Alpha.
And should now work with DT-INTS-18.

Hey Darrel,

Only works for me with MPASM assembler case sensitive option enabled.

In DT_INTS-18;
SaveFSR macro F, Pr
RestFSR macro F, Pr

And in N-Bit_Math:
SAVEFSR macro
RESTFSR macro

Edit:

MOVE?PP  macro BeerIN, Pout ; copy an N-bit variable to an N-bit variable
BeerCount = 0
    while BeerCount < PRECISION
      MOVE?BB BeerIN + BeerCount, Pout + BeerCount
BeerCount = BeerCount + 1         
    endw
  endm

Too cool --- Classic Darrel...;o)
