Or if you don't want to affect the rest of the bits in PORTB, use iorwf instead.

I am using PIC starter programmer

when I programmed it this error shows up

Code:

PICSTART Program\Verify Report

The codes which I am using is

Code:

    list      p=16F84A             ; list directive to define processor
    #include <p16F84a.inc>         ; processor specific variable definitions

    __CONFIG   _CP_OFF & _WDT_ON & _PWRTE_ON & _XT_OSC

Any suggestion why this error shows up?

Are you using a Microchip PICStart+ programmer or something called a PIC Starter?

uaefame · 19th October 2008, 07:56 AM

Don't worry problem solved I was buring the PIC 16F84a codes into PIC 16F818. Btw. I was using PIC start+.

Thanks for replying
