PIC Basic pro

[ScadaEng]

I have not done much programing in PBP, I mostly have used assembly. I'm
trying to knock out a quick program, but one detail is hanging me up. I'm
reading a 24C512 EEPROM 8 bytes at a time. I created a word (16bit) variable
to hold the memory address.

Problem is when I reach $19F8 the next address should be $0A00, but I get
$0000! The low byte works right, then I get to $1B00 and everthing is good
until I get to $29F8 and the next address is again $0000! The $0000
addresses are not really $0000, I know this from the data. Every time the
high byte reaches $0A it displays $00! I wrote a simple routine to just
count from $0000 to $FFF8. It reacts the same! I have PBP ver 2.30, is this
a problem with PBP?

My code...

temp:
memadd = $0000
Hserout [b1, b0 ]
GOTO again
again:
memadd = memadd + $0008
if memadd = $FFF8 THEN
GOTO start
ELSE
Hserout [b1, b0]
ENDIF
GOTO again

There is a whole forum dedicated to answering such questions. I strongly
suggest you try there:

Compiler bug? Try making $0008 a constant and add the constant.

Hi ScadaEng,

I've actually used this chip and Picbasic in a datalogging
application. If you can't solve your problem, please let me know and
I'll see if I can help.

I just wanted to say: You're moving away from assembly (almost
certainly a good decision) to... Picbasic Pro?

I agree with your evalulation of PBP. I never used it before this project,
and expect I won't bother with it again. A team member bought it, he did not
want to learn assembly, or any other language for programing PIC.

Thanks to all who responded!
