Tuya Wind IDE

Tuya Wind IDE (integrated development environment) provides comprehensive facilities to TuyaOS EasyGo developers.

Background

Tuya Wind IDE is provided as an extension of Visual Studio Code (VS Code) and is available in both English and Chinese. You log in to this IDE with the account of the Tuya IoT Development Platform. Tuya Wind IDE manages, distributes, and updates the TuyaOS EasyGo development kits, enabling a consistent development experience across hosts and programming tools.

Installation environment

Tuya Wind IDE supports the following environments:

• Linux virtual machine (VM) on Windows host, or Linux VM: used for developing most networked products, cellular products, gateways, control panels, IP cameras (IPCs), and network video recorders (NVRs).

• Windows: used for developing most sub-devices.

• macOS: only supports browsing and permission request for TuyaOS development frameworks, not for downloading.

Prerequisites

Step 1: Install Linux VM environment

Install VM software, VirtualBox or VMware, and create a VM. Install Ubuntu 18.04 or 20.04 on the VM. It is recommended to set the RAM of the VM to 8G.

• VirtualBox:

  1. If you use VirtualBox, set the Adapter 2 to Host-only Adapter to ensure VS Code on Windows can connect to the VM via SSH.

     

  2. If you cannot create Host-only Adapter, on the main VirtualBox window, choose File > Host Network Manager and configure as shown below. Or visit this website for troubleshooting.

     

  3. Power on your VM and get the IP address of your VM.

     

  4. Install the necessary software on the virtual machine.

     sudo apt install openssh-server openssh-client build-essential lib32stdc++6
     

If you only use a Linux VM throughout the development, see the section Install IDE for the following operations.

Step 2: Enable SSH login without password

Windows 10 or 11 has a built-in SSH client.

On the Windows host, run the following commands in PowerShell to configure an SSH login without password.

• Assume the username of the VM is vscode.

• The IP address of the VM is 192.168.56.105.

1. Generate an SSH key.

   ssh-keygen -t rsa -b 4096
   

2. Specify the username and IP address of your VM.

   $USER_AT_HOST="vscode@192.168.56.105"
   

3. Specify the location where the public key to upload resides.

   $PUBKEYPATH="$HOME\.ssh\id_rsa.pub"
   

4. Register the public key. You are required to enter the username and password of the server.

   $pubKey=(Get-Content "$PUBKEYPATH" | Out-String); ssh "$USER_AT_HOST" "mkdir -p ~/.ssh && chmod 700 ~/.ssh && echo '${pubKey}' >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
   

   

Step 3: Install Remote SSH extension

1. Install and open VS Code.

2. Click Extensions in the left navigation pane. Search for and install Remote - SSH.

   

3. Set up and connect to SSH. This example uses the IP address 192.168.56.105.

• {project}/software/apps/{application} represents the path of the application of the current TuyaOS development framework.

  Context menu	Feature	Scope
  Create Project	Create an application.	{project}/software/apps
  Build Project	Build the current application.	{project}/software/apps/{application}
  Clean Project	Clean the build of the current application.	{project}/software/apps/{application}
  Config Project	Configure the current application with a graphical interface (GUI). This action applies to product development kits that support dynamic configurations.	{project}/software/apps/{application}

Actions on development frameworks

You have a product development kit opened in the workspace.

Expand the software directory in Explorer. Right-click on software or any subdirectory and choose Show Project Information. Click Development Framework in the left navigation pane of Tuya Home. The information about the development framework is displayed on the right side of the screen.

Switch between development frameworks (Linux environment only)

If the development framework has multiple versions, you will see a drop-down menu next to TuyaOS Version.

Select the desired TuyaOS version from the drop-down menu.

Click Switch to change to that version.

Download product development kit

If a TuyaOS development framework provides a product development kit to download, the Product Dev Kit tab will appear on the page of Dev Framework information.

Click Request Permission and complete the required information accurately to get access to the product development kit.

• After you submit the request, you will get a message saying Your request for permission is being reviewed. Please wait. You can Cancel the Request for Permission during the review process.

  

• After approval, you can download the requested product development kit.

  

• The downloaded product development kit will be found in the directory software/TuyaOS/apps in the workspace.

  

View resource center

• Click Search in the top left corner of the Resource Center screen to show or hide the search box. You can narrow down your search by using multiple search fields including Development Mode (multi-select), Type Development Kit (multi-select), Dev. Platform (multi-select), TuyaOS Version (multi-select), and Permission Status (single-select). If you leave a field blank, no criteria are considered for that field in the search.

  The search results are displayed as a list below the search box. You can sort results by Development Mode, Type Dev Kit, Development Platform, or TuyaOS Version separately, or using weighted sorting.

  • Separate sorting: Click a table header to sort by that field.
  • Weighted sorting: The priority from high to low is Development Mode > Type Dev Kit > Development Platform > TuyaOS Version. Suppose that you have sorted the results by Development Mode. After you click Type Dev Kit, the results will be sorted by that field without changing the order of the Development Mode column. If you then click Development Platform, the results will be sorted by that field, with the order of Development Mode and Type Dev Kit columns unchanged.

• You can request permission to download a development kit of TuyaOS EasyGo and cancel a request that is in the review state. ​After your request is approved, the target development kit will be available to download.

  

Create an application

Expand the software/TuyaOS/apps directory in Explorer. Right-click on the apps folder and choose Create Project.

Build an application
