    Default How to use GPIO meant for OSC

    I'm not sure how to use PicBasic to configure PIC12F629 so that GP3,4,5 can be used as GPIO. Any idea without using assembly? I want to use internal 20MHz oscillation.

    Set the config to
    Code:
    __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF
    Then you can use the internal 4 MHz osc and GP3 can be used for an input.
    Then turn off the ADC

    Problem solved. Need to use the following code if not using MPASM assembler in PBP:

    asm
    device pic12F629, MCLR_OFF,INTRC_OSC_NOCLKOUT, wdt_off, pwrt_on,protect_off
    endasm
