Good morning.

I tested a PIC 12F683 with external Clock : the project is not work with internal Clock ( 8 MHz ) or external RC Clock . I use EB006 V7 and EB 004.

Thanks

The file you attached is for a PIC18F252 and you mentioned PIC12F in your post so what are you now working with and with which chip do you have a problem

i have a error file attachement.

Sorry.

In my opinion there are a few things you are not doing and that is the reason your internal oscillator is not working

(1) you have to use a C function call and set the OSCCON register to your needs
(2) if you are not clearing the watch dog in your FC diagram then you should not enable the watch dog timer
(3) why do you enable the Oscillator switch over mode as you are using the Internal OSC

Check the datasheet page 19 how to use the Internal Oscillator

My config is correct.

Thanks

You clearly did not read my post properly

however if you believe your config is correct so be it , also if you do not want to set the OSCCON register so be it too

cannot make you do this hope you get it running
