# # For a description of the syntax of this configuration file, # see misc/tools/kconfig-language.txt. # config EXAMPLES_PWM bool "Pulse width modulation (PWM) example" default n depends on PWM && NSH_BUILTIN_APPS ---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). endif
