Dear
can I remove a rect. I try with :
LCD_FillRect(1,10,9,4,RGB_RED);
LCD_FillRect(1,10,9,4,RGB_WHITE);
but the trace still exist when i draw an other object in the same place and i dislike use draw_clear.

I'm interested in the implementation of STM32 Primer demonstration software it is a care game i draw sveral obstacles in movement and my care is fixe. when an obsatacl came i move my care. for example
remove_care_left();
draw_care_right();
but when the obstacle pass i show the trace of my care after i remove it???
