PIC16f877 code crosses boundary @800h

[inventosrl]

Hello, on a PIC16f877 have this warnibg while compile with MC Studio Plus and PBP

Warn 877_0.ASM : [102] code crosses boundary @800h

Success 2134 word used

It's over the limit?s ?

It's possible to use PIC16F877A instead PIC16F877 without a bootloader?
If yes, double the program space?

Thanks a lot

giorgio

It's just a warning, no problem. You chip is big enough for your program now.
Try it and you will see that (if you mean what you programmed) your progam works.

Thanks Mat,
do you how many word I can program with success with this chip (datasheet speek about 8K) ?

thanks and regards

giorgio

[mat janssen]

The 8 K are the assembled words/
I cannot tell you how much that is in PBP.
It depends on the pbp instructions you use.
Each instruction has some overhead code in asm. LCDout has more code then x=0
If you use a gosub for your serout and serin instructions I think your code will also be shorter.

are you sure about this????????

you see this warning because you reach the end of first memory page.
4 page x 2K = 8 Kiloword memory:)

[Archangel]

It makes a difference if you are using the <B>BRANCH</B> Statement, in which case you would use BRANCHL , BranchL takes up more space than BRANCH and that is why you wouldn't use BranchL only.
