I'm using dsPIC mcu, FT810 with VisualTFT. I want to draw a line or circle with commands without clearing the current screen. When I execute the commands below, the current screen (buttons, all objects, etc..) is cleared and draws lines and circles.
Code: Select all
FT810_Canvas_Pen(5,0x0000,255);
FT810_Screen_BeginUpdate();
FT810_Screen_Circle(200,200,50);
FT810_Screen_Line(350,400,700,400);
FT810_Screen_EndUpdate();
