18F2620 pbp3 example config please

[retepsnikrep]

Having never used any 18F chips I'm after an example config section of code to have a look at before I try to migrate my code to the new pic.

My current 16F886 config looks like this

#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

My 16F886 defines look like the below any obvious issues with those and 18F2620 pic. It should be pin compatible I believe.

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  

DEFINE LCD_DREG PORTB         'PORTB is LCD data port
DEFINE LCD_DBIT 0         'PORTB.0 is the data LSB
DEFINE LCD_RSREG PORTC         'RS is connected to PORTC.0
DEFINE LCD_RSBIT 0
DEFINE LCD_EREG PORTC         'EN is connected to PORTC.1
DEFINE LCD_EBIT 1
DEFINE LCD_BITS 8         '8 lines of data are used
DEFINE LCD_LINES 4         'It is a 4-line display
DEFINE LCD_COMMANDUS 2000     'Use 2000uS command delay
DEFINE LCD_DATAUS 50         'Use 50uS data delay

DEFINE ADC_BITS 8              'Set number of bits in result
DEFINE ADC_CLOCK 3          'Set Clock source (3 = rc)
DEFINE ADC_SAMPLEUS 50         'Set sampling time in uS
   
DEFINE CCP1_REG PORTC         'HPWM channel 1 pin Port C Backlight PWM Driver
DEFINE CCP1_BIT 2         'HPWM channel 1 pin Bit 2

Thanks Peter

Anyone with a config for a similiar 18F chip then? 2525, 4525, 4620?

[retepsnikrep]

I found this example so will keep trying.

#CONFIG
__CONFIG _CONFIG1H, _OSC_HS_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
__CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
__CONFIG _CONFIG3H, _CCP2MX_PORTC_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
__CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L
#ENDCONFIG

I did a migration of code from the 16F877 to the 18F452. They are *both* kind of older now...8^) If you thought it would be useful I can dig up the configurations for comparison. I never throw old code away, I just archive it. I've got versions of this particular ported code that go back to nearly the previous centrury.

Best Regards,
Paul

If you have something it would be useful thanks.

The configs aren't so much different. If you use a programmer like an ICD2/3 or a PICKIT3, MPLAB will show you the options.

The easiest thing to do would be to set it up in a way that makes sense and simply try it.

The sub directory, "DEVICE_REFERENCE" of the PBP3 directory has an example with and all of the options listed.
