    Default Re: 18F2620 pbp3 example config please

    Thanks for the guidance here is my new 18F2620 config.

    Code:
    '------------------------------ New General 18F2620 configuration --------------------------
    '#CONFIG
    ' __CONFIG _CONFIG1H, _OSC_INTIO67_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
    ' __CONFIG _CONFIG2L, _PWRT_OFF_2L & _BOREN_OFF_2L
    ' __CONFIG _CONFIG2H, _WDT_OFF_2H
    ' __CONFIG _CONFIG3H, _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_OFF_3H
    ' __CONFIG _CONFIG4L, _STVREN_OFF_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L
    '#ENDCONFIG
    'DEFINE OSC 8   'Set PicBasic Pro processor speed to 8 Mhz   
    'OSCCON = %01110110   'Internal 8 mhz Osc and stable 
    'CMCON  = %00000111  'Comparators Off
    'T1CON  = %00110000  '$30 = Prescaler 1:8, TMR1 OFF
     
    'TRISA = %00001011   'SET PORTA0, A1 & A3 AS INPUTS, REST AS OUTPUTS
    'TRISB = %00000000   'SET PORTB AS OUTPUTS
    'TRISC = %10010000   'SET PORTC AS OUTPUTS EXCEPT PORT C4 & C7
     
    'ADCON0 = %00000001  'SETUP ADC & ENABLE ADC MODULE on AD0
    'ADCON1 = %00001110  'SETUP ADC SET REFV to VDD & VSS AN0 
    'ADCON2 = %00100010  'SETUP ADC FOSC/32 LEFT JUSTIFY TAD 8
    Below is my working old 16F886 config. Any glaring errors in the above? I'm just swapping chips and I want all functions to remain the same.

    Code:
    '------------------------------ General 16F886 configuration --------------------------
    #CONFIG
     __CONFIG _CONFIG1, _LVP_OFF & _FCMEN_OFF & _IESO_OFF & _BOR_OFF & _CPD_OFF & _CP_OFF & _MCLRE_OFF & _PWRTE_OFF & _WDT_OFF & 
    _INTRC_OSC_NOCLKOUT
     __CONFIG _CONFIG2, _WRT_OFF & _BOR21V
    #ENDCONFIG
    DEFINE OSC 8   'Set PicBasic Pro processor speed to 8 Mhz   
    OSCCON = %01110101   'Internal 8 mhz Osc and stable 
    CM1CON0 = 0    'Comparator Off
    CM2CON0 = 0    'Comparator Off
    T1CON  = %00110000  '$30 = Prescaler 1:8, TMR1 OFF
     
    TRISA = %00001011   'SET PORTA0, A1 & A3 AS INPUTS, REST AS OUTPUTS
    TRISB = %00000000   'SET PORTB AS OUTPUTS
    TRISC = %10010000   'SET PORTC AS OUTPUTS EXCEPT PORT C4 & C7
     
    ANSEL  = %00000001  'SET INPUT AN0 AS ANALOG INPUT
    ANSELH = %00000000              'Disable PortB AD
     
    ADCON0 = %10000001  'SETUP ADC CONVERTER MODULE FOSC/32 & ENABLE ADC MODULE on AD0
    ADCON1 = %00000000  'SETUP ADC LEFT JUSTIFY SET REFV to VDD & VSS

    Thanks Peter

    I moved to a new pic to gain memory space but the same program compiled for the new pic is nearly twice the size as the 16F886 version :?
    Why is that and can I get some memory back. I don't need 18F longs for instance and that is already disabled in the compiler.

    Hi,
    My guess is that it's because on the 16 series (10 & 12 too I believe) the memory is "measured" in WORDS (14-bit words if I'm not mistaken) while on the 18 series it's measured in BYTES. So I don't think your program is actually getting twice as big, it's just displaying the size of it in BYTES instead of in WORDS.

    Hi,
    What exactly does that mean, what warnings do you get and from where do you get them?

    Your code compiles and assembles fine with PBP 3.0.7.4 & MPASM 5.45. Are you using the standalone software for the PICKit2 and is it THAT software that gives you these misterious warnings?

    /Henrik.

    Make a "Complete" set of configs for any chip with ease.

    Yes the pickit 2 software states when programming that some configuration bits not in acceptable condition. It still programs and works fine but is disconcerting for users.

    That new meconfig software is interesting I see quite a few bits/parameters I have ignored/did not know about. :?
