How to setup internal oscillator in a 16F88

[arunb]

Hi,

PCM: 3.169
MCU: 16F88

I would like to setup the internal oscillator of the 16F88. I found that the header file for the device did not contain INTRC_IO, and the compiler returned an error.

I searched for previous posts related to this query, and found that most people used INTRC_IO.

I fail to understand how this can be done.

Kindly help.

thanks

PS:

Here is the extract of the header file

INTRC_IO is a valid fuse for the 16F88. It tells the compiler to use the internal oscillator and _not_ output the clock pulses to an output. You need setup_oscillator(OSC_8MHZ) in your main() to finish setting things up. This will configure the PIC to run at 8MHZ but there are several other frequencies that you can set it to.

Hi,

Thanks a lot, i got it working but only after installing PCM compiler version 3.224, i was previously using 3.169 which did not have the INTRC_IO oscillator setup.
