Implementation Results

The Ubuntu system currently only supports PAD and GIF interfaces

• WIFI: Configure the SSID and password for Wi-Fi. This button will not be displayed on the Luckfox Pico Ultra.

• OFF: Close the application.

Buildroot

Compilation

• Set environment variables:

  export LUCKFOX_SDK_PATH=<path_to_luckfox-pico_sdk>
  

  Note: Use absolute paths.

• Compile with CMake to obtain the executable:

  mkdir build
  cd build
  cmake ..
  make -j
  

Running

• Upload the compiled executable luckfox_lvgl_demo to the Luckfox Pico (using adb, ssh, or other methods).
• Set executable permissions and run:

  chmod a+x luckfox_lvgl_demo
  ./luckfox_lvgl_demo
  

Ubuntu

Compilation

• Set environment variables:

  export GLIBC_COMPILER=< glibc cross-compilation tools and prefix >
  # Such as:export GLIBC_COMPILER=/opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-  
  

  Note: Use absolute paths.
• Compile with CMake to obtain the executable:

  mkdir build
  cd build
  cmake ..
  make -j
  make install
  

Running

• Upload the entire folder /install/luckfox_lvgl_demo generated by the compilation to the Luckfox Pico (using adb, ssh, etc.).

  Note: Since the runtime depends on dynamic libraries, soft links might be lost during the upload process. It is recommended to compress the folder before uploading.

• Set executable permissions and run:

  cd luckfox_lvgl_demo
  chmod a+x luckfox_lvgl_demo
  ./luckfox_lvgl_demo
