嵌入式期末考之贪吃蛇游戏机的设计

1、嵌入式期末考之贪吃蛇游戏机的设计一、 项目总体说明1、用arm7系列型号为lpc2131的芯片设计一个贪吃蛇游戏机，其中还加入了ucos ii操作系统。2、用lcd12864来显示游戏的主界面，以及用lcd1602显示游戏开始的计时（time）、游戏所得的分数（score）和游戏通过的关数（lv）。其中“蛇”每吃的一个果实分数加1分，吃到2个果实游戏的关数加1，随着分数和关数的增加，“蛇”跑动的速度越快，“蛇”的长度也越长，游戏的难度也越大。当“蛇”碰到游戏界面的边框时，游戏结束.3、用5个独立按键来控制“蛇”的上、下、左、右，以及游戏的重新开始。二、 项目硬件设计1、电源模块：用3.3v的直

2、流电源。2、控制模块：采用独立式按键，独立式按键电路配置灵活，硬件结构简单，但每个按键必须占用一根i/o口线。在按键数量较多时，i/o口浪费较大。故只在按键数量不多时，采用这种按键。3、显示模块：采用lcd12864和lcd1602，它是一种专门用于显示字母、数字、符号、字符等点阵式lcd。其有显示质量高、数字接口、功耗低、体积小等优点。lpc2131lcd12864控制模块电源模块lcd1602图2.1 硬件模块划分三、 项目软件设计1、本设计包含了configure.h、includes.h、os_cfg.h、lcd1602.h、lcd12864.h、font.h、graphic.h等头文

3、件。以及包含了游戏显示信息gameinfo.c，按键处理keyprocess.c，游戏处理gameplay.c，游戏图形处理gamegraph.c，游戏动作处理gameactive.c等.c文件。2、主函数main.c里面包括了系统初始化函数osinit()，界面初始化函数vguiinit()，游戏初始化函数vgameinit()，以及系统开始函数osstart()。3、ucos ii操作系统中，在游戏初始化函数vgameinit()中创建了一个游戏任务vtaskgame，优先级为6；然后在游戏任务vtaskgame中创建了按键任务taskkey，优先级为10，以及显示游戏信息任务vtaski
