This module provides functions to control the voltage and current LED displays.

Since you cannot light up both displays at the same time, another function (see timer.c) will be required to call leds_ShowVoltage() and leds_ShowCurrent() alternately.

Multiplexing doesn't require exernal means but is done in this functions.
