Presetting Configuration Fuses (PIC Defines) into your Program

[Archangel]

Hello
I am new to this forum, I am a RF Engineer trying to use a 18F1220 with its internal oscillator. So far I have been unsucessfull in doing this. When using MPLAB and a IDC2 in debugger mode the Blink program works fine. When I program the device and run it on its own power it does not work. I think I traced it to the 18f1220.inc file, CONFIG1H fuse.

It sets the oscillator to External. I am not sure what the fuse should be set to. I also beleve the INTRC needs to be reconfigured for 8 MHz. Can anyone assist me? Thank You.

Hello wbubel, Welcome !
In the MPASM Suite each supported PIC has a file, named for it I. E. P18F1220.inc, in it is listed every valid config and register address. To switch to using MPASM, in MCS click view, compile and program options,click on the tab named assembler, and insert a check in the box "use MPASM", click OK and you are set. Here is what is available for config 1 . . .

;Configuration Byte 1H Options
_IESO_ON_1H       EQU  H'FF' ; Internal External Oscillator Switch Over mode enabled
_IESO_OFF_1H      EQU  H'7F' ; Internal External Oscillator Switch Over mode disabled
_FSCM_ON_1H       EQU  H'FF' ; Fail-Safe Clock Monitor enabled
_FSCM_OFF_1H      EQU  H'BF' ; Fail-Safe Clock Monitor disabled
_RC_OSC_1H        EQU  H'FF' ; External RC on OSC1, OSC2 as FOSC/4
_RCIO_OSC_1H      EQU  H'F7' ; External RC on OSC1, OSC2 as RA6
_LP_OSC_1H        EQU  H'F0' ; LP Oscillator
_XT_OSC_1H        EQU  H'F1' ; XT Oscillator
_HS_OSC_1H        EQU  H'F2' ; HS Oscillator

_INTIO1_OSC_1H    EQU  H'F9' ; Internal RC, OSC1 as RA7, OSC2 as FOSC/4
_INTIO2_OSC_1H    EQU  H'F8' ; Internal RC, OSC1 as RA7, OSC2 as RA6

You can change it in the file you posted or comment them out there and just add the ones you want at the top of your code (my preferred method). Most PICs you use DEFINE OSC 8 , but I won't say all . . .
