M5StickC PLUS2 user demo

What you’re building

M5Stack’s M5StickCPlus2 UserDemo is a PlatformIO project for hardware evaluation of the M5StickC PLUS2. Its source contains dedicated tests for the LCD, keys, MPU6886 IMU, microphone, RTC, infrared output, GPIO, Wi-Fi, BLE, and other board functions, making it useful both as a factory-style diagnostic and as reference code for individual peripherals. The project uses the Arduino framework in PlatformIO, pins the Espressif platform to 6.1.0, and declares arduinoFFT, IRremote, and M5GFX dependencies. A complete deployment requires two distinct uploads named by the README: the firmware and the filesystem image. Once both are present, the expected outcome is the device’s interactive evaluation application rather than a reusable library. The important constraint is that the PlatformIO environment is named m5stick-c even though the repository is for PLUS2; users should preserve the checked-in configuration and dependencies rather than casually substituting a newer board package or Arduino core.

Key steps

1. Clone or download the M5StickCPlus2-UserDemo project and open its root folder in PlatformIO.
2. Allow PlatformIO to resolve the checked-in espressif32@6.1.0 Arduino environment and the pinned arduinoFFT, IRremote, and M5GFX libraries.
3. Build the m5stick-c environment defined in platformio.ini without changing its partition configuration.
4. Connect the PLUS2 and upload the compiled firmware from PlatformIO.
5. Run PlatformIO’s filesystem-image upload as the separate second deployment required by the README, then reboot and work through the peripheral tests.
