In the same manner the user fixes the other states, such as CW mode (IN3=VDD,

IN4=VDD) or MaxHV0 and HV1 mode (IN3=0, IN4=VDD), by just changing the switch

position on the PCB adapter.

The status of switches IN3 and IN4 is being monitored by two SMD LED diodes, for each

switch, on the PCB adapter (D1 red and D2 green close to IN3, D3 red and D4 green close

to IN4).

As shown in Figure 11, the red light near the switch indicates state 1 (when VDD voltage is

active, the switch button is in the left position) while the green light indicates state 0 (when 0

is active, the switch button is in the right position).

When the switch button is in the center position the status is on HZ.

Method 2 (use of the motherboard based on the STM3210E-

EVAL)

The demo kit, in this solution, is made up of a motherboard based on the STM3210E-EVAL

plus the PCB demo mentioned into Section 3 (see Figure 12). It doesn't require any manual

driving because the STM3210E-EVAL microcontroller is programmed to deliver some demo

patterns.
