    I have a problem when programming nano boards, after I change it to uno it works well, even I use nano board, ide program should be uno 😅😅😅😅

    Best method for such problem will be to tighten or loosen the screw behind the i2c module in a small blue box(potentiometer of display) it will change the contrast of display due to high or low contrast these boxes appear.
    This solved my problem hope will solve yours also

    Hi I have the same issue. However, I am using CubemX Uvision STM32F103C8T6 mp i checked all solderings and they are looking good. Also, I am using 10k potentiometer when i increase the pot level white squares are going but when i decrease the pot level white squares are appearing on my LCD. What can be the issue ? Note : by the way i am using another psu for LCD, GND's are interconnected.
