[Support for Digole displays]

• It makes it incompatible with work currently progressing on uGFX V3
• It creates a custom modified version of uGFX that cannot be updated easily as we change uGFX or fix bugs
• Unless those modifications are submitted back to the repository it will breach the license agreement (any custom modifications to uGFX itself need to be contributed back under the license agreement)

I have no problem with sending back my patched to uGFX. I'm rather worrying of the fact the V2 is at the end of its life, so there is no reason to improve it at the moment.

It would be great if accelerated circle and text drawing and font loading functions will be supported in V3's driver model.

[Support for Digole displays]

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.
