Software build configuration​

The board-level configuration file defines key functional components, such as peripheral drivers, pin mapping, board support packages (BSP), and third-party libraries. By using the pre-configured board-level configuration files for the development board, you can significantly reduce the workload of hardware adaptation and driver development, thus improving development efficiency.

Interested in developing new peripherals?

Configuration features:

  • To add a new peripheral, you can write drivers directly at the application layer. BSP drivers are primarily intended for peripherals integrated on the board.
  • Peripheral requirements might vary across applications. You must adjust the configuration files based on specific needs.
  • Depending on your application requirements, you might need to configure different third-party library parameters.
  • It is recommended to use the initial config file as the base template for board-level configuration and extend or modify it as needed for your project.

How to enable configurations? Refer to tos.py User Guide > config choice.

Hardware overview​

Tuya T5AI-Board is a voice and screen multi-interaction development board based on the T5-E1-IPEX module, which is an embedded Wi-Fi and Bluetooth combo module developed by Tuya. The board is equipped with 2 microphones and 1 speaker, supporting voice recognition and playback to enable voice interaction functionality.

Through the I/O connectors on the board, you can use an LCD display stack module to implement touchscreen and camera capture capabilities. You can also design your own LCD screen, supporting multiple interfaces including I2C, SPI, 8080, and RGB.
