I have written a simple article which might be of use to some people, measuring the PIC Vdd (supply voltage) using no external components.
This builds on an older Microchip application note designed for outdated parts, so it isn't a new idea. However it works well enough for simple battery monitoring and can be added to any project on a supported PIC.
You can find it here: **broken link removed**
Happy to take comments or corrections.
