Measuring PIC Vdd with no external components using the FVR

I have written a simple tutorial explaining how to use the PIC fixed voltage reference (FVR) in order to calculate Vdd, using no external components.

It got a bit long for a blog post so can be found here: Measuring PIC Vdd with no external components using the FVR.
