Hx8872-c: Datasheet
Check VSYNC and HSYNC polarity. The datasheet indicates that the HX8872-C can accept positive or negative edges, but you must configure the “Display Timing Control” register (0xB0) accordingly.
In RGB mode, yes. The HX8872-C has no internal RAM; it refreshes directly from the incoming pixel stream. Your MCU must continuously send data. hx8872-c datasheet
