Good day, I need help to clean the screen and write again. Can someone help me with which command to execute this action? In the screens with which I worked, lcd.clear (). But on this type of screen, I do not know what command to use.
You didn't give us much to go on. Which LCD (Brand/Model), and which Arduino Library are you using?
I use lcd graphic 128x64 and the library #include "U8glib.h"
