Hi,

There is a blinky example in the SDK. Its located in the folder:

<SDK_InstallFolder>\examples\peripheral\blinky

You can download the SDK 12.2 here.

For beginners I would recommend using the pwm library, since it’s not as complicated as the pwm driver.

There is a good example in SDK_folder\examples\peripheral\pwm_library. The period will depend on the frequency(frequency = 1 /period). If you look at the example, the period is configured using APP_PWM_DEFAULT_CONFIG_2CH() / APP_PWM_DEFAULT_CONFIG_1CH(). The duty cycle is set using the function app_pwm_channel_duty_set().
