Help With 18F4620
Dear Friends,
I Use the 16f877 to many years and now I need more memory then I want to migrate for the 18f4620.
my initial header this like this:
@ device pic16F877,HS_OSC, wdt_on, pwrt_on, bod_on, lvp_off, protect_on,wrt_off
with oscillator of 20mhz external and all PORTA and PORTE as digital
it would like the friends to help with the header of the 18f4620 so that it is the definitions same to the of the 877.
in advance thankful,
Vicente.

Hi Vicente,
@ device pic16F877,HS_OSC, wdt_on, pwrt_on, bod_on, lvp_off, protect_on,wrt_off
Is a config for use with the PM (default) assembler, which you cannot use on the 18F series of pics, so you must switch up to using MPASM. First thing you must do is tell Micro Code studio about that Click File..view..compile & assembler..assembler and install a check in the checkbox use mpasm . . . .
then you need to comment out the default config in the 18F4620.inc file located in your PBP root directory, you might just as well do a copy paste of it into your MCS code page for your first 18F project (it makes a great exemplar) and then modify it from there. Some of these are quite involved. If you open up the P18F4620.inc file located in the MPASM Suite you will see every available config and register this chip has .

Re: Help With 18F4620
Ok here are the default configs from my pbp 18F4620.inc file. I show them "commented out" by adding ; just before them.
and you would install them this way:Code:;__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
Just as with your original config adding the @ symbol tells PBP to ignore the config as it is an assembler instruction and not meant for PBP to act upon it.Code:@ __CONFIG _CONFIG1H, _OSC_HS_1H & _FCMEN_OFF_1H & _IESO_OFF_1H @ __CONFIG _CONFIG2L, _BOREN_ON_2L @ __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
And you need to make them reflect what you want . .
Here are the choices from the P18F4620 file
