Config & Oscon settings 16F1825

[n0yox]

I am trying to use a 16f1847 and can not get it to blink an led I am sure this is a config problem but just can't make it work. this is my config and blink program below.

Thanks!

Just a casual observation; you're posting to a 9 year old thread instead of starting your own. In this 9 year old thread you can plainly see the working examples listed in previous posts:

#CONFIG        __CONFIG _CONFIG1, _FCMEN_OFF & _IESO_OFF & _FOSC_INTOSC & _PLLEN_OFF & _WDTE_SWDTEN & _MCLRE_OFF & _CP_OFF & _BOREN_OFF & _PWRTE_OFF        __CONFIG _CONFIG2, _LVP_OFF        #ENDCONFIG

You list your own thing and wonder why it doesn't work for you. Am I being overly critical?!?

This fixed my problem. I did not notice I had ticked 16fl1847 not 16f1847 in MeConfig . I changed "OSCCON = %11100000" to "OSCCON = %01110000" and added "DEFINE OSC 8". I am glad I figured it out before anyone answered.
