单片机写个游戏只是突然的自我（想法）~
液晶是网上买来的，TFT 2.4寸240x320竖屏的（当然也可以横屏使用，但是看上去效果肯定不如竖屏使用），RGB565也就是65K色的~
看看效果先，相机+拍照水平不行~所以……
凑合吧：
上面是游戏的启动界面，说到这里我必须推荐一个字模工具zimo221（软件在底下的附件连接里）
液晶参数：
2.4寸 TFT材质，分辨率位240x320，65K色。
控制器用的是ILI9325。
在单片机驱动时采用的是8位模式，它的高八位数据口是有效的。
驱动程序如下（AVR版本）
#include <avr/io.h>
#include <avr/delay.h>
#include <avr/pgmspace.h> //字库放在flash中需要用的
#include "symbol_16x8.h" /*这个是英文和符号的字库*/
#define A00 (PORTD &= 0XFE)/*可根据具体情况修改引脚 A0就是RS数据和指令的选择控制线*/
#define A01 (PORTD |= 0X01)
#define RES0 (PORTD &= 0XFD)
#define RES1 (PORTD |= 0X02)
#define WRB0 (PORTD &= 0XFB)
#define WRB1 (PORTD |= 0X04)
#define RDB0 (PORTD &= 0XF7)
#define RDB1 (PORTD |= 0X08)
#define CS_MAIN0 (PORTD &= 0XEF)
#define CS_MAIN1 (PORTD |= 0X10)

上面是简单的测试驱动程序。具体的由于时间问题还没写完俄罗斯程序呢~~暂时先不放出了。
接下来showshow俄罗斯的界面吧~黑白配！
当然要玩游戏键盘不可少&……可怜的四键。
