Example Code for Arduino UNO

#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.
