4.2. Play control introduction

Introduction to the entry: The entry refers to the entry of the standard version of the identification instructions we want to say & ldquo; Xiaoming & rdquo; as a wake -up word, we can identify other entries after waking up. For details, please refer to the table below:

        You can set the entry:

Wake up the answer instruction to answer the effect

Xiaoming, Xiaoming, I turned on the LED lamp that had been turned on and turned on the light.

  Turn off the lights and turn off all LED lights

  Bright brightening (the brightest) brightness from 10%-40%-100%

  Darkness has been darkened (the darkest) brightness from 100%-40%-10%

  The white light has been switched to the white light and white light LED bright (the previous state brightness)

  Change orange light to switch to orange light orange light LED bright (previous state brightness)

  Change neutral light to switch to neutral light white light orange light LED bright (previous state brightness)

  Sleep mode has been switched to the color temperature of the previous state of the sleep mode, 10%bright, and all LED lights are turned off after 5 minutes of time

  The maximum brightness has been the brightest brightness 100%

  The minimum brightness is already the darker brightness 10%

Note: 1. This version can be directly connected to PA10 without serial version chip PA10, PA11 directly connects the lights; you can also use the serial version PA6, PA7 to directly output serial signal 2. Standard version entry for testing. If you want to modify the entry, please contact the business, please contact the business Personnel 3. UART port can be used with a single -chip microcomputer. 4. The delay time is 10 seconds after the wake -up. After receiving the instructions, re -count the time.
