Hi,
I'd like to try uGFX with Digole display. It does not have frame buffer interface. It is connected over serial bus (uart, spi or i2c) and controlled by high level graphic commands like: draw_pixel, draw_line, draw_circle, draw_rect, draw_bitmap, move_rect_area, set_clip_region. It also have some flash onboard, and command sequences can be stored in it and replayed as macros. Also it has loadable fonts and can render text by itself. Here is the command reference: http://www.digole.com//images/file/Tech_Data/Digole_Serial_Display_Adapter-Manual.pdf
The serial bus limits the speed of rendering, so the window driver mode it possible but impractical. I'd like try "point and block" model. However I cannot understand quite well how can I make use of accelerated Digole's commands draw_circle, draw_bitmap, move_rect. Or is it possible at all.
