Component: Light

  • This component defines a light as a well encapsulated object.

  • A light device is defined by:

    • ledc timer which is used to control the pwm channels of light
    • mode of the ledc timer
    • frequency of the ledc timer
    • pwm channel number of the light
    • bit number of the ledc timer
  • A light device can provide:

    • iot_light_channel_regist function to add channel to corresponding channel id
    • iot_light_duty_write function to set the duty of corresponding channel and it support setting duty directly or gradually
    • iot_light_breath_write function to set the corresponding channel to breath mode and breath period can be set
    • iot_light_blink_starte and iot_light_blink_stop function to make some of channels to blink in appointed period. Note that if any channel works in blink mode, all the other channels would be turned off.
  • To use the light device, you need to:

    • create a light object returned by iot_light_create()
    • regist the light channels according the channel number by iot_light_channel_regist()
    • To free the object, you can call iot_light_delete to delete the button object and free the memory.

NOTE:

If any channel(s) work(s) in blink mode, all the other channels would be turned off. iot_light_blink_stop() must be called before setting any channel to other mode(write duty or breath).
