Unfortunately at this moment part of code connected with 5110 LCD that I'm using stopped to work.
I mean that screen is not updating at all or only one frame of animation is displayed, also actions connected with push buttons are not active
Is it possible to bypass this problem ?
I'm using modified code from LCD_5110_LMF10.ino by Rei Vilo and code made by Nathan Seidle.
In this code push button 1 changes backlight on/off and push button 2 changes from displaing animation to displaying some text
Code joined with the code from post above:
