請大神們給點(diǎn)思路

作者: Wprogrammer 時(shí)間: 2020-6-27 08:16
按鍵掃描沒那么復(fù)雜你需要做處理比如說按下去觸發(fā) 只觸發(fā)一次

作者: xuyaqi 時(shí)間: 2020-6-27 09:23
中斷里不應(yīng)該處理那么多事情，中斷只設(shè)標(biāo)志，處理在外邊。

作者: WYP8868796 時(shí)間: 2020-6-27 12:17
可是我還像這樣子設(shè)是按下去觸發(fā)一次

作者: WYP8868796 時(shí)間: 2020-6-27 13:57
可是去掉了還是會(huì)延遲

我建議你這樣做，不一定管用，你可以試試

作者: 青龍書生 時(shí)間: 2020-6-27 17:09
不要把按鍵檢測和按鍵動(dòng)作函數(shù)放在while循環(huán)中，因?yàn)檫@個(gè)時(shí)間是不一定的，你這樣做很有可能是導(dǎo)致按鍵不相應(yīng)，while中做定時(shí)器時(shí)間判斷，比如1S檢測一次按鍵是否按下，同時(shí)進(jìn)行按鍵動(dòng)作相應(yīng)，這樣不好用的話，在這個(gè)時(shí)間判斷里面做一個(gè)led燈閃爍的語句，看看是否什么地方延時(shí)過長，導(dǎo)致while循環(huán)時(shí)間過長，或者把按鍵檢測函數(shù)扔到定時(shí)器里面（正常不能這樣寫，為了找出問提），你可以這樣試試

我自己也菜，每次看到上面這種代碼，就沒有看下去的欲望，太亂

作者: WYP8868796 時(shí)間: 2020-6-28 19:27
怎么刪帖子

作者: WYP8868796 時(shí)間: 2020-6-29 01:54
能不能看看怎么實(shí)現(xiàn)按鍵長按加1
