1.包括流水燈，時(shí)鐘，計(jì)時(shí)器，簡(jiǎn)易的用4x4鍵盤控制的計(jì)算器

2.四個(gè)按鍵選擇功能，直接對(duì)應(yīng)那種一般開發(fā)板配套的紅外遙控器的1234鍵（試過是可以的）當(dāng)然仿真中不包括紅外，紅外選項(xiàng)是多余的
仿真中不包括紅外

3.計(jì)時(shí)器，上鍵運(yùn)行，下鍵清零，右鍵暫停，右鍵長(zhǎng)按切換時(shí)鐘

4.時(shí)鐘的右鍵切換調(diào)整，長(zhǎng)按到計(jì)時(shí)器，調(diào)整位會(huì)閃爍
5計(jì)算器用4x4按鍵控制

6.代碼用的匯編
