//功能：復(fù)古掌上俄羅斯方塊游戲機(jī)源代碼，包括游戲GUI，俄羅斯方塊、貪吃蛇、經(jīng)典賽車游戲、射擊障礙物游戲
v1.0:
2014-7-26 00:00:00 :完成有俄羅斯方塊游戲基本模型;
2014-7-28 02:12:03 :將原先臨時(shí)使用的延時(shí)鍵盤掃描改為外部中斷狀態(tài)位檢測(cè)鍵;
2014-7-28 20:40:37 :完成俄羅斯方塊分?jǐn)?shù)計(jì)數(shù)及分?jǐn)?shù)顯示功能;
2014-8-1 01:01:54 :將較早之前完成貪吃蛇游戲代碼合并植入;
2014-8-2 17:04:25 :整理之前的臨時(shí)源碼,使工程文件規(guī)范化;
2014-8-3 23:50:49 :構(gòu)建游戲選擇畫面基本模型,完成畫面平移效果;
2014-8-5 00:50:04 :改進(jìn)LED點(diǎn)陣底層驅(qū)動(dòng),用軟件PWM調(diào)節(jié)畫面亮度;
2014-8-7 00:53:35 :完成賽車游戲,用PWM分層掃描畫面,形成游戲畫面對(duì)比度;
2014-8-8 02:16:44 :完成賽車游戲選擇預(yù)覽畫面,并將三個(gè)游戲合并在一起;
2014-8-12 01:47:07 :將逐行掃描改為逐點(diǎn)掃描,使顯示亮度均勻;增加亮度調(diào)節(jié)功能;
2014-9-9 00:32:40 :修改及優(yōu)化若干細(xì)節(jié)；
v1.1:
2014-9-18 0:57:23 :重新布局電路，修改原先不合理的地方，為制作PCB板作準(zhǔn)備；
2014-9-19 22:02:36 :加入游戲音效，并且可以通過軟件方式開關(guān)聲音；
2014-9-21 14:59:39 :增加三位mini數(shù)碼管，實(shí)時(shí)顯示游戲分?jǐn)?shù)，數(shù)碼管共用點(diǎn)陣并行數(shù)據(jù)口；
~~~~~~~~~~~忘記備注
2014-10-20 21:30:15 :加入射擊游戲,將GUI模塊化，簡(jiǎn)化流程
