本人新手，C語(yǔ)言基礎(chǔ)較差，最近設(shè)計(jì)一個(gè)紅外防盜系統(tǒng)，要求加時(shí)鐘顯示時(shí)間和報(bào)警時(shí)段，然后自己通過仿真分別實(shí)現(xiàn)了紅外防盜和時(shí)鐘顯示（報(bào)警時(shí)段還有紕漏），但是整合成一個(gè)的時(shí)候1602顯示屏無(wú)法顯示，因?yàn)樗捷^差，自己一個(gè)人難有進(jìn)展，下面貼程序和仿真情況，請(qǐng)教各位大佬，希望能得到指導(dǎo)。
下面是兩個(gè)程序的整合，希望大佬稍微指導(dǎo)一下

估計(jì)是中斷這一塊出了問題，但是小白看不出來(lái)問題，望指教。

按下按鈕可以顯示報(bào)警時(shí)間
望指教，十分感謝
