 ===== Example =====
+This example connects a DS3231 RTC module to the MPINO-16A8R8T I²C port. The RTC's 32 kHz and square-wave outputs use different pins.
 <code cpp>
-bool IrtcSquareWave(bool enable, uint8_t frequency = IRTC_SQUARE_WAVE_1HZ,
+void setup() {
-                    bool batteryPowered = false);
+  Serial.begin(115200);
-bool Irtc32kHz(bool enable = true);
+  if (!IrtcBegin()) {  // Check the DS3231 connection and start the RTC.
+    Serial.println(F("DS3231 not found"));
+    return;
+  }
+  const bool configured = Irtc32kHz(true);  // Enable the RTC's 32 kHz output pin.
+  Serial.println(configured ? F("Output enabled") : F("RTC setup failed"));
+}
+void loop() {}

 Run each device's corresponding ''Begin'' command first. Check I²C addresses and pin sharing; if the ''bool'' return value is ''false'', inspect wiring and power.
