Applibs pwm.h

Header: #include <applibs/pwm.h>

The Applibs pwm header contains functions that interact with pulse-width modulators (PWM). PWM functions are thread-safe.

Application manifest requirements

PWM functions are only permitted if the application has the Pwm capability in the application manifest.

Hardware dependent IDs

PWM functions reference some identifiers that are hardware dependent. Hardware dependent IDs are constants that are defined in the hardware definition files for a device. For more information, see Manage target hardware dependencies.
