DC Motor Control with IFX007T (Full-Bridge)

Please modify the torque profile
in the signal generator: Torque.
Signal>>piecewise linear>>Details
define the time and value properly.
Set the signal generator to 0 for
free-running.

The DC motor control shield from Infineon technologies is one
of the first high current motor control boards being compatible
to Arduino as well as to Infineon’s XMC1100 Boot Kit. The
DC motor control shield is capable to drive two uni-directional
DC motors (half bridge configuration) or one bi-directional DC
motor (H-Bridge configuration). The implemented integrated
IFX007T NovalithIC™ half bridges can be controlled by a
PWM via the IN Pin.

In this demontration circuit you can configure your motor and
application parameters in the green text box on the left side.
