hi everyone,

I would like to have some advice on this

Following up on an example from the Wiki
I am currently using the Ds3231 along with the esp32 Loin32_lite

I have notice in the FC software RTC is up today from my laptop.
It compiles "OK" as well Displaying Numbers

when complied to the Esp32 is doesn't give me the current Time on the LCD Display.

I connect the 4 wires

Ds3231 Channel 2

Vcc-Vcc
Gnd- Gnd
SDA- PA23
SCL-PA19

Please can Anyone tell me where I am going Wrong?
