 /* CONFIG_NSH_BUILTIN_APPS - Build the PWM test as an NSH built-in function.
- * CONFIG_EXAMPLES_PWM_DEVPATH - The path to the PWM device. Default: /dev/pwm0
- * CONFIG_EXAMPLES_PWM_FREQUENCY - The initial PWM frequency.  Default: 100 Hz
- * CONFIG_EXAMPLES_PWM_DUTYPCT - The initial PWM duty as a percentage.  Default: 50%
- * CONFIG_EXAMPLES_PWM_DURATION - The initial PWM pulse train duration in seconds.
- *   Used only if the current pulse count is zero (pulse count is only supported
- *   if CONFIG_PWM_PULSECOUNT is defined). Default: 5 seconds
- * CONFIG_EXAMPLES_PWM_PULSECOUNT - The initial PWM pulse count.  This option is
- *   only available if CONFIG_PWM_PULSECOUNT is defined. Default: 0 (i.e., use
- *   the duration, not the count).
