Trying to migrate to 18F..

[Archangel]

Just an example of working configbits for internal oscillator that works on 20MHz would be great, then I could try things after that, but now I cant even get the damned thing to run..

Section 2.6 datasheet.
section 2.64 " "
32 mhz is your speed limit using PLL and internal osc.
Set it up in OSCCON register

Well, at maximum I presume ? actually I don't really understand what they mean exactly in that part of the datasheet, I would belive that I set one speed on the oscillator, and then the PLL multiplies it ? then 8x4 would give 32Mhz ? ..Ofcourse that would give me troubles to get excactly 20Mhz then, but still, it would work I think ? (but for exampe, "pause 1000" would not be one second)

Anyway, I could use another clock frequency too, the main reason to use 20Mhz is that I tried the same program on a 16f PIC with no internal oscillator, and then I used a 20Mhz xtal.

Did you write it @ __CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H ; enable int osc, disable failsafe osc enable, disable internal external switchover ?
As for ' , is a PBP compiler directive, whereas ; directs both compiler and assembler

I simply wrote:

@ __CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H

with no comment at all..

I don't have an 18F2520 to test this on, but give this a try;

asm
  __CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
  __CONFIG _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H
  __CONFIG _CONFIG3H, _CCP2MX_PORTC_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_OFF_3H
  __CONFIG _CONFIG4L, _STVREN_OFF_4L & _LVP_OFF_4L & _XINST_OFF_4L
endasm
        
DEFINE OSC 32     ' internal 8MHz x 4 with PLL enabled

blueled var LATB.4 ' prevents read-modify-write
redled  var LATB.5 ' problems

OSCTUNE = %0100000 ' turn on PLL for 4 x 8MHz
OSCCON = %01110000 ' set 8MHz internal osc
ADCON1 = %00001111 ' disable all A/D

main:
  low redled
  low blueled
  pause 500
  high redled
  pause 500
  high blueled
  pause 500
  goto main
  
  END

I get this..

Hi Glenn,

Newer versions of PBP include w = -230 in the .INC file that gets rid of the deprecated
warning.

I.E. a new version .INC file looks something like this if you have the default config settings
commented out.

   NOLIST
    ifdef PM_USED
        LIST
        "Error: PM does not support this device.  Use MPASM."
        NOLIST
    else
        LIST
        LIST p = 18F2520, r = dec, w = -311, w = -230, f = inhx32
        INCLUDE "P18F2520.INC"   ; MPASM  Header
       ; __CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
       ; __CONFIG _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H
       ; __CONFIG _CONFIG3H, _CCP2MX_PORTC_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
       ; __CONFIG _CONFIG4L, _STVREN_OFF_4L & _LVP_OFF_4L & _XINST_OFF_4L
        NOLIST
    endif
        LIST
EEPROM_START	EQU	0F00000h
BLOCK_SIZE	EQU	64

These are all you have commented out right? What version of PBP are you using?

I'm using 2.50b, and my include looks like:

However, its not the warings that I have problems with, its the errors

[Glenn]

Hmm, strange. I thought the "version 2.46" was a bit suspect, so I looked one time more, and found a "18f2520.inc.org", which probably is the correct file, and the other is something I cut'n'pasted in from someone else ?

That one looks like:

Still bot 2.50b, but 2.47, but maybe the includes only get updated when needed. (sounds logical)

Also I didnt do a clean install, I upgraded from an old version.
