StackChan Speaker

Speaker-related APIs and sample programs for the StackChan.

Sample Programs

Build Requirements

• M5Stack board manager version >= 3.2.2
• Board option = StackChan
• M5Unified library version >= 0.2.11

#include "M5Unified.h"

void setup() {
    auto cfg = M5.config();
    M5.begin(cfg);
    M5.Display.setRotation(1);
    M5.Display.setTextColor(GREEN);
    M5.Display.setTextDatum(middle_center);
    M5.Display.setTextFont(&fonts::Orbitron_Light_24);
    M5.Display.setTextSize(1);
    M5.Display.drawString("Speaker Test", M5.Display.width() / 2,
                                M5.Display.height() / 2);
}

void loop() {
    M5.Speaker.tone(10000, 100);
    delay(1000);
    M5.Speaker.tone(4000, 20);
    delay(1000);
}

Once the firmware is successfully flashed, you will hear the StackChan speaker emit tones at different frequencies — 10 kHz and 4 kHz — each lasting 1 second.
