18F2620 pbp3 example config please

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

Code:

#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.

Code:

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

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

I found this example so will keep trying.

Quote:

Re: 18F2620 pbp3 example config please

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.

Paul

Re: 18F2620 pbp3 example config please

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.

Re: 18F2620 pbp3 example config please

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

Re: 18F2620 pbp3 example config please

That's very useful thanks but how do you know which configs go on which line ? can you mix them up?

CONFIG1H? xxxx & xxxx & xxxx etc etc
CONFIG2H?
CONFIG3H?
etc

Or do you just have as many config lines as reqd?

Re: 18F2620 pbp3 example config please

Maybe I am not understanding the question, the 1H things go on the 1H line, 2H on the 2H line...

Re: 18F2620 pbp3 example config please

Hi,
Just look at the .INFO file, it has a "section" for each CONFIG you can possibly set for the device, choose one from each section if you don't know the default, like:

Code:

; This is for the 18F26K20 #CONFIG CONFIG FOSC = HSPLL CONFIG FCMEM = ON CONFIG IESO = OFF CONFIG PWRT = ON CONFIG BOREN = OFF ; And so on #ENDCONFIG

That way you don't have to know which bit belongs to which register.

Otherwise you have to resort to the datasheet and/or the .inc file for the device located in the MPASM directory, at the bottom of that file you'll find which bit goes where, like:

Code:

;----- CONFIG1H Options -------------------------------------------------- _FOSC_LP_1H EQU H'F0' ; LP oscillator _FOSC_XT_1H EQU H'F1' ; XT oscillator _FOSC_HS_1H EQU H'F2' ; HS oscillator _FOSC_RC_1H EQU H'F3' ; External RC oscillator, CLKOUT function on RA6 _FOSC_EC_1H EQU H'F4' ; EC oscillator, CLKOUT function on RA6 _FOSC_ECIO6_1H EQU H'F5' ; EC oscillator, port function on RA6 _FOSC_HSPLL_1H EQU H'F6' ; HS oscillator, PLL enabled (Clock Frequency = 4 x FOSC1) _FOSC_RCIO6_1H EQU H'F7' ; External RC oscillator, port function on RA6 _FOSC_INTIO67_1H EQU H'F8' ; Internal oscillator block, port function on RA6 and RA7 _FOSC_INTIO7_1H EQU H'F9' ; Internal oscillator block, CLKOUT function on RA6, port function on RA7 _FCMEN_OFF_1H EQU H'BF' ; Fail-Safe Clock Monitor disabled _FCMEN_ON_1H EQU H'FF' ; Fail-Safe Clock Monitor enabled _IESO_OFF_1H EQU H'7F' ; Oscillator Switchover mode disabled _IESO_ON_1H EQU H'FF' ; Oscillator Switchover mode enabled ;----- CONFIG2L Options -------------------------------------------------- _PWRT_ON_2L EQU H'FE' ; PWRT enabled _PWRT_OFF_2L EQU H'FF' ; PWRT disabled _BOREN_OFF_2L EQU H'F9' ; Brown-out Reset disabled in hardware and software _BOREN_ON_2L EQU H'FB' ; Brown-out Reset enabled and controlled by software (SBOREN is enabled) _BOREN_NOSLP_2L EQU H'FD' ; Brown-out Reset enabled in hardware only and disabled in Sleep mode (SBOREN is disabled) _BOREN_SBORDIS_2L EQU H'FF' ; Brown-out Reset enabled in hardware only (SBOREN is disabled) _BORV_30_2L EQU H'E7' ; VBOR set to 3.0 V nominal _BORV_27_2L EQU H'EF' ; VBOR set to 2.7 V nominal _BORV_22_2L EQU H'F7' ; VBOR set to 2.2 V nominal _BORV_18_2L EQU H'FF' ; VBOR set to 1.8 V nominal

And so on but again, I prefer the new way posted above.

Re: 18F2620 pbp3 example config please

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

Code:

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.

Re: 18F2620 pbp3 example config please

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.

Re: 18F2620 pbp3 example config please

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.

Re: 18F2620 pbp3 example config please

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?

Re: 18F2620 pbp3 example config please

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. :?

Darrel Taylor

Re: 18F2620 pbp3 example config please

The PICkit software expects to see a value for EVERY configuration word.

The latest versions of PBP3 do create default values for all of them.
But when you use the #CONFIG block, it overrides all of the defaults, and you should include a "Complete" set for use with the PICkit programmers.

Like you said, it will program and work ... but a complete set of configs will eliminate that warning.

Re: 18F2620 pbp3 example config please

melabs have a neat config editor meCONFIG ITS WORTH DOWNLOADING and free , or check out the DEVICE_REFERENCE folder in your pbp3 installed directory

but for now try this

Code:

#CONFIG CONFIG OSC = INTIO67 CONFIG FCMEN = OFF CONFIG IESO = OFF CONFIG PWRT = OFF CONFIG BOREN = OFF CONFIG BORV = 3 CONFIG WDT = ON CONFIG WDTPS = 512 CONFIG CCP2MX = PORTC CONFIG PBADEN = OFF CONFIG LPT1OSC = OFF CONFIG MCLRE = ON CONFIG STVREN = ON CONFIG LVP = OFF CONFIG XINST = OFF CONFIG DEBUG = OFF CONFIG CP0 = OFF CONFIG CP1 = OFF CONFIG CP2 = OFF CONFIG CP3 = OFF CONFIG CPB = OFF CONFIG CPD = OFF CONFIG WRT0 = OFF CONFIG WRT1 = OFF CONFIG WRT2 = OFF CONFIG WRT3 = OFF CONFIG WRTC = OFF CONFIG WRTB = OFF CONFIG WRTD = OFF CONFIG EBTR0 = OFF CONFIG EBTR1 = OFF CONFIG EBTR2 = OFF CONFIG EBTR3 = OFF CONFIG EBTRB = OFF #ENDCONFIG

ps not sure why your asking for PIC18F4520 config info in a 18F2620 thread why not start a new one ?

Re: 18F2620 pbp3 example config please

according to the book if I have the right code

Quote:

217 Attempt to Generate Code in Non-Code Segment

Due to the Harvard Architecture (split code and data spaces) of the PICmicro
MCUs, instructions may only be executed from CODE space (ROM). This error
indicates that an attempt was made to generate opcodes in the data or
EEPROM segments. In general, only the DS pseudo-op is legal in the data
segment and DS, DB and DW are the only legal pseudo-ops in the EEPROM
segment.

if that doesn't help you might need to post your latest code
