买模块的时候人家给的代码只有几个简单的
void LCD_Draw_Circle(unsigned short x0, unsigned short y0, unsigned char r, unsigned short color); //画圆
void LCD_DrawFullCircle(unsigned short Xpos, unsigned short Ypos, unsigned short Radius, unsigned short Color);
void LCD_Fill(unsigned short sx, unsigned short sy, unsigned short ex, unsigned short ey, unsigned short color); //填充区域
void LCD_DrawLine(unsigned short x1, unsigned short y1, unsigned short x2, unsigned short y2, unsigned short color); //画线
void LCD_DrawRectangle(unsigned short x1, unsigned short y1, unsigned short x2, unsigned short y2, unsigned short color); //画矩形
