Hi! I just want to ask you if you can help me find lcd display like this. But mine has to be JHD 162a, 659m10, and the rohs must be 1930. I can't anymore, I need this for my research, please help me

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.
It is not pin 3 issue. Check another wire connection
Nice video
Thanks

After all connections given display is light on, not displaying row brackets& symbols & letters, then
display is working or not
Check the soldering.
Thank you bro. 👍🏻
👍
Another way problem the black dotted boxes are only displays top row half only
Backblight is not glowing
Nothing really works anymore. Buy a brand new car and I bet you find faults. DIY electronics are worse.
