Converting to MPASM

[Darrel Taylor]

Hi Brian,

In the CONFIG line for MPASM, there must be 2 underscores before the word CONFIG, and a space after it. And some of the options should be different

@ __CONFIG _HS_OSC &_BODEN_OFF &_PWRTE_ON &_WDT_ON &_CP_OFF

And keep in mind that MPASM is CASE Sensitive (unless you use the command line option to disable case sensitivity).

HTH,

Thanks Darrel,

I copied your line into my code. It tellls me I now have 2 errors but only one error gets shown with three messages on the bottom of the MCSP screen.

Error [118].....Overwriting previous address contents (2007)
Message [306] Crossing page boundary..ensure page bits are set.
Message [306] Crossing page boundary..ensure page bits are set.
Message [306] Crossing page boundary..ensure page bits are set.

Do the page bits get set autometically?

What does error 118 mean and how do I fix it?

2007 is the address of the CONFIG word in the PIC. The "error [118] Overwriting previous address contents" means that it's already been set.

In the 16F877.inc file in your PBP folder, comment out the __CONFIG line with a semicolon ";" Then try again.

Just remember, that once commented, every time you write a program for a 16F877, you''l need to have a CONFIG line at the top of your program, since the defaults aren't there anymore.

You may also want to add _LVP_OFF to the CONFIG in your program to turn off the Low Voltage Programming input.

And <b>@ errorlevel -306</b> will turn off the Crossing page boundary warnings
