WebJan 27, 2024 · The onRequest and onReceive callback functions are called from inside an ISR. Thus you cannot use any code in there, that relies on interrupts to work. Serial writes or prints for example will only work, as longs as the buffer is not full (since the actual communication is handled by interrupts). If the buffer is full, the serial code will ... WebReading the time form your RTC Is just as simple, in fact the process can be followed neatly inside the function displayTime(). You will need to define seven byte variables to store the …

WebJul 29, 2024 · Figure 2: DS3231 Datasheet showing Crystal Aging According to its datasheet for the first year, its accuracy is about ppm i.e. there’s a deviation of 1 second in every 1 million seconds. If we calculate this time in the day, then for the first year there might be a deviation of 1 second in every 11.57 days.
