Hi,
I have PCB test circuit with 18LF4520, and I'm testing a compass module (AK8963C), which is working.

I'm just finishing second update PCB, with 18F4620. The compass module doesn't work with this one?

Both PCB CLKOUT PINS show the same on an Oscilloscope.

I've checked continuity, voltages etc, but can't find any errors.

Does anyone have any ideas what I can check to get it working please?

Camerart.

None of us have a crystal ball. Post a schematic and your code.
Hi S,
Here is the SCH and the CODE.

Note: I'm not using the 9255 Compass anymore. I'm now using an AK8963C compass chip on a breakout board, attached photo. Connected SPI 4xWIRE.

Note: Running on internal crystal 8MHz

C.

Does the schematic reflect what you are currently using or doesn't it?

Why is it showing 2 pics?
