   • Ensure the correct board and port are selected in the IDE settings.

3. Connecting Sensors and Peripherals:

   • Utilize the GPIO pins, I2C, UART, SPI, and Grove connector to interface with external sensors and peripherals.
   • Refer to the pin configuration table for the correct pin assignments.

• Power Management: Monitor the battery level and charge the device regularly to prevent unexpected shutdowns.
• Heat Dissipation: Ensure adequate ventilation to prevent overheating during prolonged use.
• Firmware Updates: Keep the firmware up to date to benefit from the latest features and bug fixes.
• Code Optimization: Optimize your code to make efficient use of the ESP32's resources and capabilities.

1. Device Not Powering On:

   • Ensure the USB cable is properly connected and the power source is functioning.
   • Check the battery level and charge if necessary.

2. Unable to Upload Code:

   • Verify the correct board and port are selected in the Arduino IDE.
   • Ensure the device is in bootloader mode by pressing the reset button.

3. Display Not Working:

   • Check the connections to the display and ensure the correct libraries are included in your code.
   • Verify the display initialization code is correct.

• Resetting the Device: Press the reset button to restart the device and clear any temporary issues.
• Checking Connections: Ensure all connections are secure and correctly aligned with the pin configuration.
• Consulting Documentation: Refer to the official M5Stack documentation and community forums for additional support and resources.

#include <M5StickCPlus.h> // Include the M5StickC Plus library

void setup() {
  M5.begin(); // Initialize the M5StickC Plus
  M5.Lcd.setRotation(1); // Set the display rotation
  M5.Lcd.fillScreen(BLACK); // Clear the display
  M5.Lcd.setTextColor(WHITE); // Set text color to white
  M5.Lcd.setTextSize(2); // Set text size
  M5.Lcd.setCursor(10, 10); // Set cursor position
  M5.Lcd.print("Hello, World!"); // Print message to display
}

void loop() {
  // Add your main code here, to run repeatedly
}

This example code initializes the M5StickC Plus, sets up the display, and prints "Hello, World!" to the screen. Make sure to install the M5StickC Plus library in the Arduino IDE before uploading the code.

By following this documentation, users can effectively utilize the M5StickC Plus 2 in their projects, troubleshoot common issues, and optimize their development process.
