GUI flickering & fluctuating between screens during eeprom read write.

[Shiv09]

Hello All,

I am working on the touchgfx project and have an application where I have created some screens and performing the different operations while button pressed.

I am writing and reading the data content to external EEPROM, eg, some 10-15 parameters while button is pressed and reading it while other button is pressed.

Before adding the Eeprom operation My Screens and operations were working fine and fluently, but after adding the code for writing the parameters to eeprom, the screens started to flicker between screens and the GUI is getting distorted. 

This is not normal behavior, Can any one suggest how shall I take care of it or what would be the best way to perform external Eeprom read write operations, without interrupting the GUI ?

Regards,

Shi
