TMR0 overflow problem

[jderson]

Now, I'm really confused. After reading the datasheet again, I tried to add the following lines:

CONFIG1H = %00001000 'INT OSC Switchover & FSCM disabled, INT OSC enabled
CONFIG2L = %00000001 'BOR, PWRTEN disabled
CONFIG2H = 0 'WDT disabled
CONFIG3H = 0 'MCLR disabled
CONFIG4L = %10000000 'DEBUG, LVP, STVR disabled
CONFIG5L = %00000011 'CODE PROTECT disabled
CONFIG5H = %11000000 'EEPROM & BOOT BLOCK not code protected
CONFIG6L = %00000011 'WRITE PROTECT off
CONFIG6H = %11100000 'EEPROM & BOOT BLOCK not write protected
CONFIG7L = %00000011 'TABLE READ not protected
CINFIG7H = %01000000 'BOOT BLOCK TABLE READ not protected

MPASM says "Syntax error". Why? Programs won't compile using PBP 2.50, it says use MPASM. Is this correct?

Skimask-

Yes, I read Melanie's fine post. That's why I put those lines in the program. She also said to use what's in the .INC file. There are only three items in my .INC file, none of which correspond exactly to the datasheet.

Might want to re-read that post again then...because you're not really supposed to add lines to your main program...you can, but there's a few things you have to do first.
The items in the INC file are also listed in another file, the config options that is.

And where might I find the "config options" file?

Sorry...I thought I typed more in there Don't know what happened. I'll blame it on Windows
Umm....config options...stand by for further edit...

Ok, when I need to know what my actual config options are, as defined by the assembler, MPASM (because the compiler, PBP, could generally care less what your config options are), mine are located at:
C:\Program Files\Microchip\MPASM Suite\
And in your case it would be the:
P18F1220.INC file, way down at the bottom of the file. Paste those options into the PBP INC file as described by the above link and you should be good to go.
OR, as described by the link above, you can comment out all of the config options in the PBP INC file, and paste them as one line assembly lines into your main program.
Personally, I almost always use the same config options for each style of chip, therefore, I comment out the 'stock' config options in the PBP INC file for the chip I'm using, and paste in the config options that I always want, as described in the link above. That way, every time I use a particular chip, I'm always configuring it the same way, every time, no surprises. If I go to a different chip, I modify PBP's INC file for that chip, and do it the same way, as described in the link above.

Thank you for your help. I found the file, and I will add them to my program (in the proper manner) tomorrow. I still wonder why PBP does not support this device, when the sales literature says it does. (Not that it matters for the problem I'm having!)
