  • tal_log_init: Configure the log output to make it more convenient for debugging
  • board_register_hardware: A unified entry point for registering peripheral driver hardware on the development board
  • lv_vendor_init: LVGL initialization, binding the display and touch to LVGL
  • ui_init: UI design initialization, component application and callback initialization
  • lv_vendor_start: Create an LVGL task
  • tal_thread_create_and_start: Create a new thread to initialize the TF card, microphone, speaker, RTC, QMI, BAT, GPS (only useful with GPS modules), WIFI, and GPIO, and periodically process the gyroscope, real-time clock, obtain battery voltage, and update GPS data
  • __wifi_ble_task: WIFI task, scanning the number of nearby WIFI networks

Result demonstration

• LCD screen display

• Parameter description

Demo description

• Tuya IoT app is a minimally functional app demo provided by the Tuya AI + IoT platform
• As a simple, cross-platform, cross-system switch example that supports multiple connections, this switch can be remotely controlled (out of office), LAN controlled (within the same LAN), and Bluetooth controlled (without available network) through the Tuya App and Tuya Cloud service.
• Before using switch_demo, you need to know the following terms:
  • TuyaOpen dedicated license
  • PID
  • Device Pairing
  • DP

Hardware connection

• Connect an LED to GPIO47 pin
• Connect the development board to the computer

Code analysis

• cli_cmd.c: Some command-line operations for viewing and manipulating the information and status of switch_demo.
• reset_netcfg.c: Implement network configuration reset function for IoT devices
• tuya_main.c: The main function of switch_demo.
• tuya_config.h: Tuya PID and authorization information (the example comes with a PID designed for Waveshare's APP, you can click to copy the product), created and obtained on the Tuya developer platform, please refer to the document TuyaOS > Create Product.

Result demonstration

• This demo will not light up the screen
• Support Bluetooth provisioning
• Support Wi-Fi hotspot mode provisioning
• Receive MQTT control data from the cloud and automatically respond
• Receive LAN TCP control data from the App and automatically respond
• OTA function
• Default App control panel

• Click to control the GPIO47 to light up or off

Demo description

• your_chat_bot is a large-model intelligent chatbot based on Tuya.AI open source, and the program is located in the development environment, specifically at \TuyaOpen\apps\tuya.ai\your_chat_bot.
• Voice is collected through the microphone, and after voice recognition processing, it realizes dialogue communication, interactive response and ridicule functions, and the chat content can be displayed on the screen in real time.
• Supports Tuya voice smart agents, and supports four chat modes:
  • Long press conversation mode: The user needs to press the button for a long time to start voice input, and release the button to end the voice input.
  • Button-triggered conversation mode: The device defaults to standby mode upon power-on. A short press of the button puts the device into listening state, allowing the user to speak and converse with the AI agent.
  • Wake-up conversation mode: After the user wakes up the device with a wake word, they can have a single conversation, similar to interacting with a speaker.
  • Free conversation mode: After the user wakes up the device with a wake word, they can have continuous conversations. If no conversation occurs after waking up, the device will return to standby mode after 30 seconds. The device needs to be woken up again before the next conversation.
• Supports interrupting the current conversation locally through button operations.
• Supports various status prompt sounds, such as network pairing, offline, wake-up, etc.
• Supports various display screens and multiple UI interfaces:
  • WeChat style
  • Chatbot
  • Swipe subtitles (for small OLED screens)
• Supports adjusting device volume through the app.
• Performing three power-on and power-off operations consecutively can put the device into network configuration mode.
• Supports real-time switching of AI agent roles on the app side.

Hardware connection

• Install the speaker (8Ω 1W/8Ω 2W)
• Connect the development board to the computer

Code analysis

• app_chat_bot.c: Chatbot functionality implementation
• app_chat_bot.h: Chatbot functionality header file
• app_system_info.c: System information-related functions
• display: Display interface module.
• reset_netcfg.c: Device power on/off reset function.
• tuya_main.c: Application entry.
• app_display.h: Display module header file
• app_system_info.h: System information (such as network status, memory, etc.)
• reset_netcfg.h: Device power on/off reset function header file
• tuya_config.h: Device authorization code and other configuration information

Result demonstration

• The screen will light up after power-on, and the speaker will play "Entering network configuration mode"
• Download "Smart Life", and after installation, click to enter:
  • Turn on Bluetooth -> Click the + in the upper left corner -> add device, you can then scan for the corresponding device, click the avatar to connect
• After hearing "I am now connected", start the conversation, and you can begin chatting
• Default App control panel

• The current demo provides test firmware, which can be used to test whether the onboard device functions properly by directly flashing the test firmware
