Hi,
I'm don't speak English very well, so sorry for mistakes.
I'm working with display LCD touchscreen like this https://www.electrofun.pt/display-lcd-touchscreen-shield-arduino docked in the arduino mega and I would like to show the date and time with DS3231 like this https://www.electrofun.pt/modulo-rtc-ds3231-relogio.
I connect DS3231:
-SDA: pin 20
-SCL: pin 21
and the respective power pins
I created the code and hadn't error, but when I sent for the arduino, the touchscreen went blank and didn't show what I had programmed, and just show up when put in comment, both the variables as the programming to show these variables.
Can you help me solve this problem?
Below is my programming to take a look.

int hora = rtc.getTime().hour;
int minuto = rtc.getTime().min;
float temperatura = rtc.getTemp();
int dia = rtc.getTime().date;
int mes = rtc.getTime().mon;
int ano = rtc.getTime().year;
