Based on UCGUI3.98, h file configuration 240 * 240 size, 8bit per pixel. If you compile failed,try to open guiconf.h some macros.
The file to achieve a clock, draw the clock background can use a solid color background, bitmap background, jpeg background. Pointers that draw clocks can use Line or polygons. To switch between these functions use the macro control as described in the macros for controlling the drawing mode between "Ctrl Marco Begin" and "Ctrl Marco End" at the beginning of the file and their corresponding comments.
The entire code contains many notes for beginners. I also groping for a week, some code reference other documents on the network, there are imperfections forgive me.
