Notes and version constraints

• The source contains no explicit commands other than the CMake line above; additional commands must be taken from the tutorials.
• Flashing Pico2 firmware using the official MicroPython firmware may cause the device to go unrecognized – use the firmware provided in the package instead.
• CMake files must not contain Chinese characters (including in comments), otherwise project import may fail.
• For RP2040/RP2350: press BOOT and RESET simultaneously, release RESET first then BOOT, so the USB mass storage appears.
• The exact version of the VS Code extension package is 0.15.2; updating to newer versions is possible but not specified in the source.
