標(biāo)題: 單片機(jī)按鍵+定時(shí)程序循環(huán)問題
麻煩大佬給看一下，這個程序中，count賦值大一點(diǎn)（目前是1），按鍵在按的時(shí)候就不正常了，單片機(jī)源碼如下：

先把count改成char型試試。

好的，我試下，謝謝！

if(num>=10)
            {
                     num = 0;
                     count ++;
            }

把count++改成count=1；試試

num = 0;

count = 1 的話，后面如何增加這個數(shù)值呢？因?yàn)槟壳癱ount = 1 就是1秒鐘，后面如何做時(shí)間加長處理呢？

Key_Scan函數(shù)已經(jīng)放在T0中斷函數(shù)中運(yùn)行，其中uiKeyTimeCnt1就是1ms計(jì)時(shí)單位，鍵值ucKeySec=2就含有長按1秒的時(shí)間信息，再增加count判斷就多余了。把number、num、count統(tǒng)統(tǒng)去掉。

count是1秒定時(shí)，里面有一個循環(huán)模式，這個變量值是需要調(diào)整的，有可能是20秒，也有可能是60秒，所以是需要這個count的
