hello all,
i am building a data logger to save the operation time and still working on the basics features to save time with the RTC DS1302 and to write in a file in the SD Card.
my problem is after tracing the code i once i call
SD.Begin();
the time clock is return time as 2165-165-165 27:165:85
while before that it’s working fine and returning correct time.
I am Using WeMos D1 for this project in order to send data through WiFi and to log it in case no connection.
