| /* 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). |
