DinMeter Arduino Example Program Compilation and Upload

1. Preparation

• 1. Arduino IDE installation: Refer to Arduino IDE Installation Guide to complete the IDE setup.
• 2. Board Manager installation: Refer to Basic Environment Setup Guide to install the M5Stack Board Manager and select the M5DinMeter board.
  
• 3. Dependency library installation: Refer to Library Manager Installation Guide to install the M5Unified , M5GFX and M5DinMeter driver libraries.

2. Operation Instructions

3. Port Selection & Configuration

• Connect the device to your PC via USB. After the driver installs, select the corresponding board and COM port in the Arduino IDE.

  

4. Program Compilation & Upload

Hello World

1. In the Arduino IDE, create a new sketch and paste the Hello World example below.
2. Compile and upload to your device. The screen and Serial Monitor will display “Hello World!”

#include <M5Unified.h>
 
//––– Adjust these to position your text –––
static const int16_t X_POS = 0;   // horizontal pixel offset
static const int16_t Y_POS = 60;  // vertical pixel offset
 
void setup() {
  auto cfg = M5.config();
  M5.begin(cfg);
 
  M5.Display.setTextSize(2);
  M5.Display.setCursor(X_POS, Y_POS);
  M5.Display.println("Hello World!");
 
  Serial.begin(115200);
  Serial.println("Hello World!!!");
}
 
void loop() {
  // nothing here
}

After uploading, you can see the following effect:
