Hello,

I want to run my PIC16F18313 at 4 MHZ for this i configure the chip like this: But when I Measure the CLKOUT Pin there is a 8 MHZ sawtooth.

After adding the following code: Everything is fine. That means I can measure a 1 Mhz square

So now my question, should it work also by configure the chip via Project options ot is this a Bug?

Hello,

The clock speed setting in the project options is used to configure delays and baud rates etc. It must match the clock speed of the hardware but it does not in itself set the hardware clock speed.

The INTOSC helper component can be useful when using the internal oscillator.

Hi Ben,

The 'clock speed' setting just the speed for calculations is a recurring source of confusion, would it be possible to add a remark to the dialog or change the text? There is plenty of screen real estate available in that dialog for more text.

Good suggestion there Jack. We have changed the label text to the following.

Clock Speed (Hz): Defines delay related timings
