Welcome to Why the RTC is Returning 165/165/2165 or Garbage – And How to Fix It! ⏰
In this tutorial, we’re going to learn the main reasons why your RTC might return "165/165/2165" or garbage data, and how to address these issues to get reliable date and time readings in your projects.
The most common causes of this problem are:
1. Hardware connection issues – loose wires or incorrect wiring can lead to invalid readings.
2. Library mismatches – using an incompatible RTC library with your module can cause garbage output.
3. Calling RTC retrieval functions from an ISR – accessing the RTC from an interrupt routine can lead to unstable results.
We’ll walk through each of these causes and provide practical solutions to ensure your RTC works correctly every time.
Happy learning!
