This topic walks you through the concepts and development process of the TuyaOS Gateway Development Framework.
|Type development kit||A type development kit, a TuyaOS-based development framework, is designed to help you quickly develop IoT products for different use cases and roll them out to the market. A type development kit consists of the build framework, development environment, demo, library, and header file. For more information, see Type Development Kit.|
|Product development kit||A product development kit, based on a particular type development kit, provides the complete source code used to develop products specific to a vertical. For more information, see Product Development.|
|Development mode||TuyaOS provides two development modes:
|Release notes||The release notes for the type development kits in the Gateway Development Framework. For more information, see Release Notes.|
In TuyaOS SDK development, if you cannot find the development kit for your platform, contact your account manager and provide the cross compiler toolchain you use. Tuya will upload the development kit accordingly
This section describes how to download the development kit from Tuya Wind IDE.
See Tuya Wind IDE and proceed with the installation.
Log in to Tuya Wind IDE using your account of the Tuya IoT Development Platform.
Click Resource Center and search for the development kit you need. Select a Development Mode and Type Development Kit to show the supported chip platforms.
In TuyaOS SDK development, if you cannot find the platform you need, contact your account manager and provide the cross compiler toolchain you use.
Select a platform and click Search to show all the available TuyaOS versions. Find the latest version and click Request Permission.
Wait for your request to be processed. After it is approved, you can click Create Framework on the home page to download the development kit.
If you use TuyaOS OS development, you can download the product development kit. Choose Dev Framework > Product Dev Kit and request permission for the kit you need.
The product development kit is downloaded to

Designed with a cross-platform approach, TuyaOS abstracts away the differences between hardware and systems by providing the TuyaOS Kernel API (TKL). When you port TuyaOS, you only need to adapt TKL.
TKL API definition:
TKL API examples:
You need to adapt and port TKL when using TuyaOS SDK development, but it is not necessary for TuyaOS OS development.
The standard Linux APIs, such as for the OS, file system, and network, come with examples of TKL implementations.
Most APIs can be used directly, but a few might not be fully compatible with all products, hardware, or chips. In such cases, you need to adapt them accordingly.
TuyaOS provides a unified build framework, allowing you to write application code and build projects in Tuya Wind IDE.
If you use TuyaOS OS development, it is recommended to do custom development on top of the product development kit. If you use TuyaOS SDK development, it is recommended to develop your application on top of the sample project.
How to build a project in Tuya Wind IDE:
Right-click the name of the target project in the
apps directory and choose Build Project from the menu.
Enter the version number in the format
x is a number) and press Enter.
It is strongly recommended to use Tuya Wind IDE to develop and build a project. However, if you have an existing build framework, you can integrate the development kit into your framework as a component.
This section describes the key steps to integrate the TuyaOS development kit into your existing build framework.
Copy the TuyaOS
include directories to your build framework, and write a build rule to specify the
include path. Write the link rule to specify the
lib path and link the respective library.
When linking a library, it is recommended to add the option
-Wl,--start-group <link library> -Wl,--end-group. This enables you not to take care of the order of dependency when multiple static libraries are used.
software/TuyaOS/vendor/<development environment>/tuyaos/tuyaos_adapter directory to your build framework, and write a build rule to specify the
tuyaos_adapter/include path. Build all the
.c files in the
Copy the directory of the sample app to your build framework and build all the
.c files in this directory.
This way, the development kit can be integrated into your build framework.
