M5.Display.drawString("PaperMono Buzzer Test", M5.Display.width() / 2, M5.Display.height() / 2);
}
void setup()
{
M5.begin();
M5.Display.setEpdMode(epd_mode_t::epd_fast);
drawScreen();
}
void loop()
{
M5.Speaker.tone(4000, 200);
delay(2000);
M5.Speaker.tone(8000, 200);
delay(2000);
}After the device powers on, it plays two tones with different frequencies every 2 seconds.
