Nextion and large quantities of component updates

Projects Programming
1

I have a Nextion page that I need to load 60 setting values too. They are stored on the arduino in a 2D array.

I thought about using wept to load them into eeprom at system load and then display the values on page load. But each one of these boxes will have a number field that will have up/down arrows and are adjustable by the user. So when they have changed them will need to rept them back to the arduino.

I’ve tried it and it works but not sure I want to write to the eeprom when not needed. I wish there was a feature on the nextion similar to arduinos eeprom.update where it only writes value if it’s different.

Any other suggestions for an efficient way to populate all 60 boxes?

You could use FRAM, then just transfer the module when you need to read/write data by a different machine. They come 8Kx8 for only a few dollars and they are much faster then EEPROM.
