This section provides usage instructions for each functional example in the factory firmware, helping users understand the onboard resources and interface usage of the ESP32-C6-Touch-LCD-2.8. Before running the examples, please prepare the following components:

Required Components​

  • ESP32-C6-Touch-LCD-2.8 ×1
  • TF Card ×1
  • Speaker ×1
  • Battery ×1

Wi-Fi Configuration​

  • Before use, turn on a 2.4GHz Wi-Fi hotspot. The ESP32-C6 supports only 2.4GHz Wi-Fi 6 and does not support 5GHz Wi-Fi.
  • Wi‑Fi SSID: weather-wifi
  • Wi‑Fi Password: 12345678
  • Band: 2.4GHz
  • The Wi‑Fi SSID and password in the factory firmware are fixed. The hotspot you use must match the above configuration; otherwise, the device will not be able to connect.

Precautions​

⚠️ USB Download Precautions (Important)​

The development board uses USB for programming

If the port is not recognized, please enter Boot mode:

  1. Press and hold the BOOT button.
  2. Connect the USB cable to the computer
  3. Release the BOOT button.

After the download is complete, power cycle the board to run the program.

BAT_PWR Button Test​

  • After connecting the battery, the device can be powered directly by the battery and will turn on the screen (controlled by hardware circuitry, not software).
  • Long‑press the BAT_PWR button for about 2 seconds to power off. After power‑off, press the BAT_PWR button again to power on.

Firmware Download​

  • The factory firmware is located in the Firmware directory of the example package.

Example Overview​

  • The firmware uses the ESP-Brookesia component to implement an APP-style interface, including Settings, 2048 Game, Weather, Drawing Board, XiaoZhi AI, Gravity Ball, Sensor, and other apps.

App Example Introduction​

tip
  • To exit an app, swipe up from the bottom of the screen.
  • Swipe up from the bottom and pause in the middle of the screen to view recently running apps; swipe up again to close and terminate the APP process.

Settings APP​

  • Supports Wi‑Fi scanning.

  • Allows adjusting display brightness, viewing TF card size, and checking the MAC address in the product info section.

  • Long‑press the BOOT button to return to the brookesia interface.

Sensor APP​

  • Displays real‑time data from various sensors.
  • When you rotate the board, the gyroscope data changes accordingly; the RTC clock increments by the second.
  • When you cover the temperature/humidity sensor with your hand, the humidity value will gradually rise, while the temperature value usually changes little or remains stable.

Drawing Board APP​

  • Allows freehand drawing.

2048 APP​

  • Displays the current score and the best score in real time, and supports restarting the game with one tap.

Weather APP​

  • After the device connects to the network, it will automatically fetch and parse the current day's weather information for Shenzhen within a few seconds.
  • For secondary development, modify the ESP‑IDF example 06_wifi_weather as needed.

Gravity Ball​

  • This example demonstrates a gravity ball app based on the six‑axis IMU. The ball moves in real time according to the board's tilt angle and orientation changes.
  • Before use, place the board flat on a table and wait for the ball to finish loading before picking it up.
  • Tap the BOOT button to reset the ball's position.
