基于單片機(jī)的貪吃蛇游戲設(shè)計(jì)
利用三天假期把貪吃蛇游戲移植到了我的單片機(jī)開(kāi)發(fā)板上，單片機(jī)是STC89C52只有8K的FLASH，本來(lái)想移植俄羅斯方塊的但是移植編譯之后大約有10K的空間。
下面是我拍的視頻，優(yōu)酷的鏈接：http://v.youku.com/v_show/id_XNjIxNjM2MzUy.html高手勿噴吶！
程序中使用的器件有：
?。?）STC82C52配置有片內(nèi)RAM512B，片內(nèi)FLASH存儲(chǔ)器 8KB，時(shí)鐘為8MHz。
?。?）2.4寸TFT彩屏，最大支持RGB565格式有65536種顏色。主控制器為ILI9325，程序中使用的是8位數(shù)據(jù)模式，所以運(yùn)行比較慢。
?。?）紅外遙控器，采用的是HS0038芯片。紅外協(xié)議是NEC協(xié)議，32位數(shù)據(jù)位，第一字節(jié)為標(biāo)識(shí)碼，第二字節(jié)為其反碼，第三字節(jié)為數(shù)據(jù)位，第四字節(jié)為數(shù)據(jù)位反碼。
下面是我的程序：
lcd.c是TFT液晶屏的驅(qū)動(dòng)程序，key.c是紅外芯片的驅(qū)動(dòng)程序，snake.c是貪吃蛇游戲的程序。lcd.h,key.h以及snake.h是對(duì)應(yīng)的頭文件，里面有一部分與平臺(tái)相關(guān)的定義
移植的時(shí)候只要做對(duì)應(yīng)的修改即可。下面上一下游戲的界面：
下面開(kāi)始貼源代碼啦：
第一代碼，lcd.c是TFT彩屏ILI9325的驅(qū)動(dòng)程序。
