18F1220 newbie

[richard]

is that the version of mpasm that shipped with pbp ? (looks like the one noah used)

the pbp 2.6 inc file for an 18f1220 looks like this

i'm guessing your config should look like this , you need to check the config word for each setting
I you version is older then , I can't help much more

asm
        __CONFIG    _CONFIG1H, _XT_OSC_1H
        __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
        __CONFIG    _CONFIG4L, _LVP_OFF_4L
endasm

Hi Richard, my P18F1220.inc does not look anything like that.
I tried your config suggestion with slight mod ( see below) but it still does not work. I also tried with a copy of the .inc from MPLABX - also does not work.

Hi, I have now installed MPLABX , PBP3 and MCSX. Now I get [ASM ERROR] 18F1220 NOVA BX.ASM (30) : Symbol not previously defined (_INTIO2_OSC_1H) .
I've tried a lot of permutations and found that some config statements don't give an error and others give a similar error ( or errors ) as above.
Any ideas?

[richard]

in your pbp 3 directory you should have a folder called DEVICE_REFERENCE
have a look in there for a pic18f1220.info file , all the possible config are listed there
IN A FORMAT like this

#CONFIG
CONFIG WDTEN = OFF
CONFIG PWRTEN = ON
CONFIG BOREN = OFF

CONFIG DEBUG = OFF
CONFIG XINST = OFF
#ENDCONFIG

Hi Richard , thank you for your patience.
I tried all the changes you suggested but could not get it to work. I reverted back to PBP 2.6 and downloaded
MPLAB 8.9 which contains MPASM v5.5. I now get a bit further with seven lines of errors
similar to "overwriting previous address contents (0000)" .

Hi Richard , It's blinking now. I changed the config settings in the .inc file that exists in the
PBP 2.6 folder and I have no config statements in my source program.
Thank you very much for guiding me on this problem. Your help has given me confidence to continue migrating to 18F.

Hi Richard, I'm using PBP 2.6. Not sure if my MPASM shipped with it.

Thank you

two osc configs will confuse things try , also note the indentation

asm    or it could be #config
    __CONFIG _CONFIG1H, _INTIO2_OSC_1H
    __CONFIG _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H
    __CONFIG _CONFIG4L, _LVP_OFF_4L
    __CONFIG _CONFIG3H, _MCLRE_OFF_3H
endasm   or #endconfig

its been ages since I used pbp 2.6
pbp3 is easier
