78K0/Fx2 – CAN it!
14.2 ADC demo
This sample program realizes a simple voltage meter. By using the integrated ADC, the voltage supplied to
80 of 78K0/FF2 device, is measured. The input voltage is adjusted by
t can
ADC on input channel 0, port P
potentiometer R14. The board shows the measured voltage by driving the LC display. The output forma
be changed by pressing button SW2.
