Hi Wp100 .Thank you for your help
I have a simple "Classic TAIT programmer" hardware and I use "PICpgm programmer" software. Always, I used a pic 16f877 for my hardware .
Now I am trying to start use 16f887 PIC. I thougt it will not be a problem because it is almost the same PIC as 16f877.
I made a hardware and software for 16f877 and it works. I thought to use the same software for pic 16f887 the one I wil change with 16f877, only I have to compile it in MPLAB for 16f887.
Hex file is burnt with no problems, but device is not working properly. A programm is huge. It is kind of clock with some table testing capabilities.
I think it might be config bits setting. I am not well known with these bits setting. On 16f877 I allways used thesse settings : XT oscillator - set, Power up - set, Brown out - set, and all other not set. That was allways good for me. I thought to use the same config bit settings for 16f887. What config bit settings should I use for pic 16f887 ?
