Hello Arduino Lover
I use this Library for my 2.9" ePaper Display I wonder how I can display something what rapidly
changes lets use millis(); but all what I get is blur. Is their a trick to do this job
Have a good one !!
millisNew = millis();
display.setTextColor(GxEPD_LIGHTGREY);
display.setCursor(30,60);
display.println( millisOLd );
display.setTextColor(GxEPD_BLACK);
display.setCursor(30,60);
display.println(millisNew);
display.updateWindow(25,48,100,20);
delay(250);
millisOLd = millisNew;
I did it this way is not Perfect, but it works, maybe someone has a better approach
do you have a question? or what is the intention of your post?
You are not a Newbie anymore, are you?
With GxEPD you need to do one full update before you use partial updates. The first partial update should be to full screen with the same content as the last full update. See GxEPD_Example. In GxEPD2 this is done automatically. Newbies or new projects should use GxEPD2.
Sure My approach works but it's not Perfect, I have to ask , to find a solution is a mental thing, sorry for that, but Arduino ESP32 give me a goal in life.
