Hello
i have three of touchscreen 1.77inch. And i only get white colour on them.
When i read the docs about the screen on https://cdn.shopify.com/s/files/1/1509/1638/files/AZ004_A_1-10_EN_B078JBBPXK_2fa41c1a-e2d6-4e1f-9090-495d706ba54c.pdf?v=1721030870
I wonder if it's mandatory to have Atmega328P Board istead of connecting the screen direct to Arduino Uno?
I have try some graphics test and code with only green colour screen. But only white screen. And sucessful text in serial monitor.
