 ===== 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>
 void setup() {
   Serial.begin(115200);
-  if (!IrtcBegin()) return;  // Check the DS3231 RTC connection and begin operation.
+  if (!IrtcBegin()) {  // Check the DS3231 connection and start the RTC.
-  IrtcSquareWave(true, IRTC_SQUARE_WAVE_1HZ);  // Set the RTC square-wave output.
+    Serial.println(F("DS3231 not found"));
-  Irtc32kHz(true);  // Enable or disable the RTC 32kHz output.
+    return;
-}
-void loop() {
-  if (Iup(0, IdigitalRead(0, 5))) {  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state. / Return true only at the instant the input changes from OFF to ON.
-    IrtcSquareWave(false);  // Set the RTC square-wave output.
-    Irtc32kHz(false);  // Enable or disable the RTC 32kHz output.
   }
