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)
{

}
}
?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
