Thanks to Tuya Smart for the event.

The world is big, let’s doodle together.

1.  Use Tuya serial port debugging assistant to simulate MCU docking with Tuya CBU module to implement network distribution.

Use USB_TTL to connect to the CBU module, baud rate: 9600

(Result: The test distribution network is normal)

2.  Arduino programming boot program (that is, programming the program downloaded from the serial port)

3.  How to realize communication between Arduino soft serial port and Tuya CBU module

Change part:

SoftwareSerial mySerial(9, 10); // RX, TX

TuyaWifi my_device(&mySerial); // Use soft serial port

mySerial.begin(9600); // Software serial port initialization

The rest of the code is consistent with the hardware serial port

4.Transplant  DP points​

#define DPID_SWITCH_LED 20 // Switch ( can be issued and reported )

#define DPID_WORK_MODE 21 // Mode ( can be issued and reported )

#define DPID_MUSIC_DATA 27 // Music light ( only distributed )

#define DPID_DREAMLIGHT_SCENE_MODE 51 // Colorful scene ( can be distributed and reported )

#define DPID_LIGHTPIXEL_NUMBER_SET 53 // Point / length setting ( can be issued and reported )

unsigned char dp_array[][2] =

{

  {DPID_SWITCH_LED, DP_TYPE_BOOL},

  {DPID_WORK_MODE, DP_TYPE_ENUM},

  {DPID_MUSIC_DATA, DP_TYPE_STRING},

  {DPID_DREAMLIGHT_SCENE_MODE, DP_TYPE_RAW},

  {DPID_LIGHTPIXEL_NUMBER_SET, DP_TYPE_VALUE},

};

Change: my_device.set_dp_cmd_total(dp_array, 5); //incoming all DPs and their types array, DP numbers

5.  Use the library to light up the WS2812
