Instant Interrupts - Revisited

[Acetronics2]

Thank you Darrel,

That's nice from you.

By the way ... I also modified "a bit" your Elapsed Timer to get only HHHH:MM:SS, using The Timer 1 Clock with a 32.768 Khz Xtal.

That gives more computing time for other tasks ... especially other interrupts.

Darrel,

I downloaded your Instant Interrupts files and I am having trouble compiling them. I am using MPASM assembler with PBP. I take your 3 files and try to compiler them straight from what I downloaded.

On the DT_INTS-14.bas I get the following:

Error [113] c:\pbp\pbppic14.lib 1141: Symbol not previously defined (INT_ENTRY)

On the ReEnterPBP.bas I get the following:

Warning [207] c:\pbp\reenterpbp.asm 217: Found label after column 1 (INT_RETURN)

Warning [207] c:\pbp\reenterpbp.asm 313: Found label after column 1 (INT_RETURN)

Error [116] c:\pbp\reenterpbp.asm 313 : Address label duplicated or different in second pass (INT_RETURN)

The Elapsed_INT.bas compiles without any errors but gives me the following warning:

Warning [207] c:\pbp\elapsed_INT.asm 237: Found Label after column 1 INT_RETURN


Do you have any ideas what might be wrong?

[Darrel Taylor]

What do you have in the main program?

Error [113] c:\pbp\pbppic14.lib 1141: Symbol not previously defined (INT_ENTRY)
Usually means there isn't an INT_LIST macro.

The files won't compile without it.

As of yet I have not put your code into my main program. I was just trying to compile each on their own. If I understand you correctly, your code needs to be put of another program or it will not compile. Is that correct?

[Darrel Taylor]

That's correct!

Alain,

Well, you may have noticed I didn't get the "GLOBAL" for INT_ENABLE/DISABLE put in the last version of DT_INTS-18.
It turns out that GLOBAL is a reserved word for MPASM. It's used with relocatable code.

I could have used GLBL or GLBAL I suppose, but somehow

@ INT_DISABLE GLBL

Seems even more cryptic than

GIE = 0

I still think it should be in there, as should PERIPHERAL, HIPRIORITY and LOWPRIORITY.

But I'm not sure what the best way is, AKA less confusing.

Any thoughts?

Hi, Darrel

What about

@ G_INT_DISABLE and @ G_INT_ENABLE ??? ... would be simple enough. ... and it's just "ordinary" macros !!!

Remember the goal was only to use something simple to remind ( in other words: to use for datasheet non-lovers !!! )

To me, GIE = 0 is also the simpler ... But, as you've seen, nowadays nobody dares to read the datasheets !!!




The Tractor computer soft is just finished (!)... I had some precedence headaches ( particularly with // !!! ), and it was really difficult to see what was wrong ...

despite result was good for setting a flag, operation was wrong !!! ... and was no way to cancel that flag ...

Now, I must translate my comments to English ...

Alain
