config EXAMPLES_PWM
	bool "Pulse width modulation (PWM) example"
	default n
	depends on PWM && NSH_BUILTIN_APPS && LIB_BOARDCTL
	select BOARDCTL_PWMTEST
	---help---
		Enable the Pulse width modulation (PWM) example

if EXAMPLES_PWM

config EXAMPLES_PWM_DEVPATH
	string "PWM device path"
	default "/dev/pwm0"
	---help---
		The path to the PWM device. Default: /dev/pwm0

config EXAMPLES_PWM_FREQUENCY
	int "Default PWM freququency"
	default 100
	---help---
		The default PWM frequency.  Default: 100 Hz

config EXAMPLES_PWM_DUTYPCT
	int "Default PWM duty percentage"
	default 50
	---help---
		The default PWM duty as a percentage.  Default: 50%

config EXAMPLES_PWM_DURATION
	int "Default PWM duration"
	default 5
	---help---
		The default PWM pulse train duration in seconds.  Used only if the current
		pulse count is zero (pulse count is only supported if PWM_PULSECOUNT
		is not defined). Default: 5 seconds

config EXAMPLES_PWM_PULSECOUNT
	int "Default pulse count"
	default 0
	depends on PWM_PULSECOUNT
	---help---
		The initial PWM pulse count.  This option is only available if
		PWM_PULSECOUNT is defined. Default: 0 (i.e., use the duration, not
		the count).
