18F452 "Unknown Processor" errors

All .INC files comes with PBP disks. So chances are that you deleted it, renamed it or corrupted it. Delete the whole PBP directory, then reinstall your disk.

Be sure you really have MPASM as it don't comes with PBP.

Wich IDE are you using to compile your code??? MPLAB, MicroCode Studio, CodeDesigner ???

if the problem persist do one of the following

1. Post your code and much about what you use
2. Do the rain dance, with a sweet pickle in your right ear, sing "Abba Dancing Queen", from the end to the begining then go outside naked and say loud "I'm an extra terrestrial comming directly from Tharg planet and i love eating humans"

if the last work... i really want to see it

it looks like my installation of the MPLab IDE was messed up. The "P18F453.INC" file should have come with it, I think. Will try fixing that.

ok, reinstalling MPLab did the trick. The program compiled and uploaded fine, except for these warnings from the compiler:

Warning[230] C:\PBP\18F452.INC 20 : __CONFIG has been deprecated for PIC18 devices. Use directive CONFIG.
Warning[230] C:\PBP\18F452.INC 21 : __CONFIG has been deprecated for PIC18 devices. Use directive CONFIG.
Warning[230] C:\PBP\18F452.INC 22 : __CONFIG has been deprecated for PIC18 devices. Use directive CONFIG.

But, whatever they mean, it works! Thanks for the help!

In the latest version of MPASM the __CONFIG directive has been deprecated for PIC18 devices. MPASM now expects to see CONFIG followed by the list of options.

The default config fuse directive in your PBP 18F device header files still use the old __CONFIG approach. It will still work (until Microchip makes it fail), but MPASM issues the warning to remind us to use the new CONFIG directive.

This way;

__CONFIG _CONFIG1H, _OSCS_OFF_1H & _XT_OSC_1H
__CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_128_2H
__CONFIG _CONFIG4L, _LVP_OFF_4L

Should now look like this;

CONFIG OSCS=OFF,OSC=XT,WDT=ON,WDTPS=128,LVP=OFF

Look in your MPLAB installation directory at device specific P18Fxxx.INC header files for fuse options available for the 18F part you're using.

It's just a warning for now, and the old method still works, but I wouldn't be surprised if a new version of MPASM pops up one day and starts rejecting the older __CONFIG directive.

thanks bruce. i can see the rationale for the change.

Do you mean to say that
Q1 this statements should be copied into the code or the .inc file??
Q2 and both works fine with mpasm??

This way;

__CONFIG _CONFIG1H, _OSCS_OFF_1H & _XT_OSC_1H
__CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_128_2H
__CONFIG _CONFIG4L, _LVP_OFF_4L

Should now look like this;

CONFIG OSCS=OFF,OSC=XT,WDT=ON,WDTPS=128,LVP=OFF
