Just the usual laptop -> USB-cable -> PICkit2/demo-board.
That is, the demo-board directly connected to the PICkit2.
The demo-board has the usual couple of 100 nF caps.
No other power supply.
The 5V is stable at aprox 4.92 V the whole time.
And the application "works" (the ADC reading is displayed
on the 4 LEDs, well, at least some of the reading).
