Question
High efficiency method of side mixing and side display
Due to THE MCU's RAM and ROM limitations, I wanted to use the pre-stored 4bit bitmap data to mix the 16-bit color and display as I mixed.The current method is to use GUI_DrawPixel() every time the color is mixed in the control's custom redraw function.One problem is that GUI_DrawPixel needs to send the set XY command to the screen every time, which is inefficient.Excuse me everybody has the method of what efficiency high point？
