RTC Nextion enhanced in all pages

Hello everyone !


I have a NX4024K032 Nextion enhanced with an arduino Mega and micro SD card.


My program has 8 pages where the first page (page0) shows all RTC using 6 global variables like this: year, month, date, hour, minutes, seconds. This function is ok.

My question is how can I check these variables from the others pages WITHOUT to put others 6 aditional variables in each page.

is this possible to do ?

I try to read all time this datas from any PAGE because I have to send this to save in a micro SD card.  All time must send this date and hour


Thanks for your help
