26 Oct 2007 6:34 16f628 internal oscillator

I have this 16f628 and I want to utilize all the available pins.

To achieve this I need to remove the crystal oscillator so that I can use this pins.

I am using proton compiler and I'm not familiar on setting this internal oscillator.

Any help would be appreciated.

Thank you guys in advance.

Hi My Friend
making the 628 run on its internal Osc is just a matter setting the fuse at program time.

To start with do it when programming time via the programmer

compile your code then on you programmer set the fuses manual.

What programmer are you using?

i hope i help you

As of now I'm using pickit 2 I guess that is one of the downside of this programmer.

The fuses cannot be configured manually. (not sure yet)

BTW what is the maximum oscillating frequency (internal)?

Use MPLAB 7.62 and the PICkit 2 will work fine, fuses and all. No different than an ICD2 as far as using it goes.

As for the 16F628A it has two internal speeds 4MHz and 48KHz
