Atom EchoS3R Arduino Program Compile & Upload

1.Preparation

• 1.Arduino IDE installation: Refer to the Arduino IDE Installation Guide to complete the IDE setup.
• 2.Board manager installation: Refer to the Board Manager Installation Guide to install the M5Stack board manager and select the board M5AtomS3R (Atom EchoS3R and AtomS3R use the same main controller).

• 3.Library installation: Refer to the Library Installation Guide to install the M5Unified and M5GFX libraries, and install all required dependencies as prompted.

2.Port Selection

Connect the device to the computer using a USB-C cable. Press and hold the side reset button for 3 seconds until the green LED flashes. The device will then enter download mode, and you can select the corresponding main controller and device port in Arduino IDE.

3.Program Compile & Upload

#include "M5Unified.h"

void setup() {
  M5.begin();
}

void loop() {
  M5.Speaker.tone(7000, 100);  // frequency, duration
  delay(1000);
  M5.Speaker.tone(4000, 20);  // frequency, duration
  delay(1000);
}

Copy the above program into Arduino IDE, click the upload button, and after compilation and uploading, the program will use the speaker to play beep sounds.
