I’m very beginner in Arduino.
I have one Arduino Mega and I bought one LCD 128x64 RG12864K-BIW-VBG RAYSTAR OPTRONICS
I tried to build my first project with Arduino and I used as reference to display: Graphic LCD 128x64 tutorial by Technowave G - YouTube
Also I use U8g2 to writte a simple Hello World
My problem is, I have very, very low contrast on display, very hard I see that is something on display and also some lines is flickering
I’m asking, maybe someone have similar project and it’s working and maybe can share with me wiring and library used.
I attached some pictures, I don’t know if is visible, but contrast it’s maximum.
What i’m doing wrong, please some help
