variable problems

[Darrel Taylor]

Unless you will be writing part of your program in Assembly Language, there's no need to worry about the PIC's banking system.

PicBasic Pro handles all that for you.

The access locations can be useful in ASM, and can save a bunch of CPU time by reducing the number of Bank changes. But PBP does not use that area, for that purpose.

So just define your variables without ANY modifiers, and everything should work just fine.

I am using ASM for interrupt initialization, but I don't think that would matter as far as variables go. Actually that's the reason why I'm trying to learn about these modifiers; if I let Picbasic handle the variables, my board goes haywire, freezes up and doesn't hold the var values as debugging showed, however everything works if I manually set the vars to set locations.

I don't know why this is happening, and maybe I coded something wrong or discovered a picbasic bug; not sure, but manually assigning a var to location, say, $70 that are accessed say at 0x0100 to 0x1EC0 address (in other words across all banks), works and letting picbasic handle this var doesn't work.

Maybe someone has a suggestion actually what might be wrong.

P.S. watchdog timer kicks in sometimes also because I notice a board reset and I have auto-insert clear watchdog timer set so that really does show that the board froze up.

Thanks for any information.

Well, let's see some real code so we can help you figure out the real problem.
