Pic18F4455 Voltage measurement

To measure the voltages higher then the VCC (supply voltage of the ?C) i was thinking of using the well-known and simple voltage divider using resistors.

- Discover the possibilities of measuring DC voltages in a range from 0VDC to 30VDC.
- Use the Onboard A/D converter from the PIC18F4455/PIC18F2550 range.
- Measure different DC voltages at a time.
- Try to do the measurement without using an external ref voltage.
- Measure: 5V DC
- Measure: 9V DC
- Measure: 12V DC
- Use Xtal
- Display the voltages on an 4-line char display in 4-bit mode
