  [arduino code examples for A6v3]-06 how to DS3231 RTC clock

* DS3231 RTC with Arduino
*
* This program demonstrates how to use the DS3231 RTC (Real-Time Clock) module with the Arduino.
* It includes functionality to:
* - Initialize the DS3231 RTC module
* - Read the current date and time from the RTC
* - Set the RTC time based on a serial command:Command format: DYYYY-MM-DDTHH:MM:SS
*    Set date and time command example: D2024-09-19T11:50:22
*    print current date and time command: current time
*
*
* Hardware Connections:
* - SDA: GPIO 12
* - SCL: GPIO 11

  Problem with names in port monitor - KC868_16A
Posted by: Poczwara13 - 01-14-2025, 01:24 PM - Forum: "KCS" v2 firmware system - Replies (5)

Hello,

I shared the recording with the problem in the link below:

https://drive.google.com/file/d/1NRPJGf5...KmdYB/edit

The problem occurs when the page is refreshed and affects the names of the input and output ports.

Alternatively, can you add a few additional characters to the port descriptions?
