App structure of the software example H-bridge for the Motor Control Shield is shown in
7
Figure 13. The output voltage is controlled by the two PWMSP001 Apps. The ramp time is controlled by a
8
third PWMSP001 App via interrupts. The inhibit signals are software controlled by the IO004 App.

To change the PWM frequency from 25 kHz to a different value the settings of both PWM App instances
12
PWMSP001/0 and PWMSP001/0 have to be modified. There, the PWM frequency can be easily set to different
13
values.
