FAQ

Q: What platforms are supported by the AI voice conversation example?
  • This product features an onboard ES8311 audio codec chip, onboard speaker, and SMD microphone, enabling voice conversation functionality.
  • Integration with various platforms has been verified, supporting mainstream platforms such as Doubao, Wenxin Yiyan, ChatGPT, etc. The examples will be gradually released to ESP32-AIChats
Q: The ESP32-S3-Touch-LCD-3.5B fails to open the camera after flashing Xiaozhi source code?

  • Open the ESP-IDF terminal and enter idf.py menuconfig. Configure as shown below, selecting the corresponding OV5640 camera.

  • Enable the DVP interface.

  • Save the configuration. Recompile and download.

Q: Why does compilation fail?

  • If the following situation occurs when compiling a project in Arduino IDE, you should modify Partition Scheme -> 16M Flash (3MB APP/9.9MB FATFS).

  • When an ESP-IDF project fails to compile, delete the build, managed_components, and dependencies.lock folders, then compile again. If the error persists, check the ESP-IDF version and whether the CMakeList.txt in the project directory is recognized correctly.

Q: The module keeps resetting?
  • This situation is caused by a program crash that makes USB malfunction. Press and hold the BOOT button while powering on; the module will enter download mode. Flashing the firmware (program) will resolve the issue.
Q: The first program compilation is extremely slow. How to handle it?
  • It's normal for the first compilation to be slow, just wait patiently.
Q: After successful flashing in ESP-IDF, the serial port shows 'waiting for download...'. What should I do?
  • If the development board has a reset button, press it; if not, power cycle the board.
Q: How can I measure the battery voltage on this product?
  • This product includes an onboard AXP2101 that can measure various battery parameters, such as chip temperature, charging status, whether power is connected, battery voltage, charging voltage, battery capacity, etc.
Q: Why does the battery percentage reading fluctuate significantly on this product?
  • The AXP2101 estimates battery capacity based on battery voltage, but battery capacity is not linear. Therefore, percentage readings may fluctuate considerably, especially when plugging/unplugging the charger, under load changes, or as the battery ages. The measured percentage is only a reference; voltage should be used as the actual measure of battery level.
Q: Can you provide the 3D CAD file of the case?
  • No.
Q: Are both buttons on this product programmable?
  • Yes. The two buttons on this product are BOOT and PWR, with the following functions:
    • BOOT: If pressed while powering on, the development board enters download mode (commonly used when the program freezes or the USB GPIO is occupied). Under normal operation, the button state can be read via GPIO0 (low level indicates pressed). It can detect single-click, double-click, multi-click, and long-press actions.
    • PWR: When powered on, long-press for 6 seconds to power off. When powered off (the device can still charge the battery), single-click to power on. Under normal operation, the button state can be read via the expansion IO EXIO6 (high level indicates pressed). It can detect single-click, double-click, multi-click, and long-press actions (long-press must not exceed 6 seconds, otherwise the device will power off).
Q: Does this product support Bluetooth?
  • The core chip of this product is the ESP32-S3R8, which supports 2.4GHz Wi-Fi, low-power Bluetooth 5, and other wireless communication functions. It includes an onboard chip antenna with optimized gain to support Bluetooth and Wi-Fi. For details, please refer to ESP32-S3 datasheet.
Q: Does this product support Chinese character display?
  • This product uses the ESP32-S3R8 as the core and connects to the screen via QSPI. It fully supports Chinese character display, provided the following conditions are met:
    1. Character encoding support: strings in UTF-8 encoding can be rendered to the screen.
    2. Font support.
    3. Display library support: both LVGL and Arduino_GFX support Chinese display.
Q: Which chips are used for the screen on this product?
  • AXS15231B, a display driver all-in-one chip.
Q: Is this product waterproof?
  • No, it is not waterproof. Keep it dry during use.
Q: How can I check which COM port I am using?

Windows System:

  1. Through Device Manager: Press Windows + R to open the "Run" dialog box. Type devmgmt.msc and press Enter to open Device Manager. Expand the "Ports (COM & LPT)" section. All COM ports and their current status will be listed here.
  2. Using Command Prompt: Open the Command Prompt (CMD), type the mode command, which will display status information for all COM ports.
  3. Check the hardware connection: If an external device is already connected to a COM port, the device typically occupies a port number. You can determine which port is being used by checking the connected hardware.

Linux System:

  1. Check using the dmesg command: Open the terminal.
  2. Check using the ls command: Type ls /dev/ttyS* or ls /dev/ttyUSB* to list all serial devices.
  3. Use the setserial command: Type setserial -g /dev/ttyS* to view configuration information for all serial devices.
Q: Why is there no output on the monitor after successful programming and running, even though the code is fine?
  • The Type-C programming/debugging port on the ESP32-S3-Touch-LCD-3.5B is directly connected to the ESP32-S3 USB. In the Arduino IDE development environment, printf output is supported. To also support Serial output, you need to enable the USB CDC On Boot function or declare HWCDC. Refer to the demonstration in the example code. In ESP-IDF, ESP_LOGD and ESP_ERROR_CHECK are typically used for output.
Q: Can you help me review or modify my code? Can you help me modify the code?

This product is positioned as a development board, not a finished product. This product is positioned as a development board, not a finished product. The product ecosystem is based on the ESP32 core, which is very mature and the development environment is very friendly. We do not assist in modifying code. Please let the makers and geeks use their DIY skills. If you have questions, you can ask our engineers for answers.
