3.软件设计

 3.1 绘制单个方块函数

/*************绘制单个方块**************/
void Lcd_DrawDiamond(u16 x,u16 y,u16 c)
{
  u16 i;
  LcdWriteReg(0x2A);//设置x坐标
  LcdWriteData((x>>8)&0xff);//x坐标高8位
  LcdWriteData(x&0xff);//x坐标低8位
  LcdWriteData(((x+8)>>8)&0xff);//x坐标高8位
  LcdWriteData((x+8)&0xff);//x坐标低8位
  LcdWriteReg(0x2B);//设置Y坐标
  LcdWriteData((y>>8)&0xff);//Y坐标高8位
  LcdWriteData(y&0xff);//Y坐标低8位
  LcdWriteData(((y+8)>>8)&0xff);//Y坐标高8位
  LcdWriteData((y+8)&0xff);//Y坐标低8位
  LcdWriteReg(0x2C);//设置x坐标
  for(i=0;i<9*9;i++)LcdWriteData(c);
}
​3.2 清空一行显示
/******************消除一行*******************/
void Lcd_ClearOneLineDisplay(u16 y,u16 c)
{
  u16 i=0;
  for(i=2;i<LCD_WIDTH-98;i+=10)
  {
    Lcd_DrawDiamond(i,y,c);
  }
}
​3.3 定义屏幕大小数组，保存方块图形掉落位置状态信息，显示区域宽度为220，高度为480
