Hello World — IDE basics

Run an official example with zero code and learn the core TuyaOpen IDE chain: pick board → build → flash → read logs.

Beginner15 minIDE

This is the smallest closed loop — you write no code, you just run an official example through the IDE. Finishing it teaches the core operation chain: pick board → build → flash → read logs.

Prerequisites​

  • The IDE extension is installed — see Install TuyaOpen IDE.
  • A T5 AI Board (T5AI_Board), connected to your computer with a USB cable.

Step 1: Enter from the board catalogue​

  1. Open VS Code or Cursor and confirm the TuyaOpen IDE extension is enabled.

  2. Click the Boards icon in the left activity bar to browse the supported boards, chips, and SoC platforms with their full specs.

  3. Find T5AI_Board in the list and open its detail page. You see a large amount of developer material — purchase links, schematics, datasheets, source code, 3D models, and more.

Step 2: Create an example project​

  1. On the T5AI_Board detail page, click New Project with This Board.

  2. Fill in a project name and a location, then click Create project.

  3. The IDE derives a project into your workspace and auto-configures the T5AI_Board board-level information.

Step 3: Build​

Open Project Details in the IDE sidebar, then click Compile in Firmware Operations and wait for the build to finish. The Project Details view shows the firmware status visually.

Expected output (build success):

====================[ BUILD SUCCESS ]===================
 Target    : T5Board_project1_QIO_1.0.0.bin
 Output    : .../dist/T5Board_project1_1.0.0
 Platform  : T5AI
 Chip      : T5AI
 Board     : TUYA_T5AI_BOARD
 Framework : base
========================================================

Step 4: Flash​

  1. Connect the board with USB. The T5AI_Board has two serial ports — one for flashing and one for logs. Make sure your USB cable carries data, not just power.

  2. Click Flash. If you are unsure which port is the flash port, try either one. Here COM4 is selected.

Expected output (flash success):

write  T5AI  COM4  921600
  File   .../bin/T5Board_project1_QIO_1.0.0.bin  2.0 MiB
  Range  0x00000000 -> 0x001FF1E0

Handshake         OK
Flash ID          OK
Unprotect         OK
Write [1/1]       OK
...
Flash OK  38.9s

Step 5: Monitor the serial log​

Click Monitor and select the log port — here COM3. When you see hello world, your first TuyaOpen project is running.

Expected output:

[01-01 00:00:00 ty D][tuya_app_main.c:8] hello world
note

If you do not see hello world, the monitor most likely opened too late — the line prints the moment flashing completes. Do not close the monitor terminal; flash again and the message appears.
