Has anyone used the built-in RTC ?
I have just started using a 3.2 Enhanced but I cannot find any code examples for setting or reading the RTC, and very little in the Nextion Docs.
Can anyone help ? Thanks.
There are 7 numeric system variables, rtc0 (year), rtc1 (month), rtc2 (day), rtc3 (hour), rtc4 (minute), rtc5 (second), and rtc6 (dayOfWeek).
Setting the RTC is done by setting rtc0 to rtc5, for example rtc0=2020, rtc1=9, rtc2=21, rtc3=8, rtc4=41, rtc5=30. rtc6 is read-only and will automatically be set according to rt0-rtc2.
Reading the RTC is simply done by reading these system variables and using these to update display components.

Many thanks - I will explore this.
/ The following is going to execute before we load this current page:
//
// Read the EEPROM to know if we are in 24 hour mode:
repo bt24.val,20 // reads from EEPROM address 20 into the dual state button
//
// I am going to read the EEPROM to know in what setting the brightness is:
repo h0.val,10 // reads from EEPROM address 10 into the slider
repo n0.val,10 // reads from EEPROM address 10 into the n0.val
//
// Read the EEPROM to know if the DST is enable:
repo btdst.val,30 // reads from EEPROM address 30 into the dual state button
