[Beginner Tutorial] How to get started with PICBASIC PRO Demo, MPLAB & PICKIT 2

[citationjet100]

I am programming with a 16F628A and can't figure out the code for the PIC configuration. I am using a 20mhz crystal and have configured the program with the DEFINE OSC 20. I am at a loss to get the chip config to be accepted though.
Thanks

Hi,
For 20MHz operation you need to set the HS_OSC option. If you're using PBP3 then try

#CONFIG
   __config _HS_OSC & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
#ENDCONFIG

/Henrik.

My little bit of advice don't forget:-
:-

MCLRE_ON means that MCLRE acts as a reset pin. It needs to be tied to +5v with a resistor (10K or similar)

Caught me out several times…. Or turn just off if you don't need a reset facility.

I copied the code to the program file and still got syntax errors.

#CONFIG
__config _HS_OSC & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
#ENDCONFIG

I am using MicroCode Studio Pro to complile the program and PICKIT2 for programming.
Thanks

. . . and no mention of which version of PBP . . .
Hi Dave,
The configs you are using are only for version 3.xx and later versions to come.
If you are using any earlier version this thread has everything you need to know: http://www.picbasic.co.uk/forum/showthread.php?t=543

ver 3.xx Make sure you have some spaces just before __config as Assembly is fussy that way
