什么代碼這部分復(fù)制錯(cuò)了

全是P1^1輸出了，但是改完也還是顯示一樣的東西

好奇怪

先驅(qū)動(dòng)一位顯示，成功了在擴(kuò)展

教你一個(gè)方法。
1、先顯示一個(gè)段，看看亮在何處。
2、再顯示另一個(gè)段，看兩者的位置關(guān)系。
3、逐漸增到7個(gè)段，你就可以拼成0-9了。

1.先檢測(cè)引腳是否連接正確
2.硬件正確調(diào)用基本的驅(qū)動(dòng)函數(shù) 顯示一小段
3.成功顯示一段再?lài)L試顯示數(shù)字

太長(zhǎng)了看不下去，又沒(méi)什么難度，你能不能發(fā)一下，應(yīng)該顯示什么字，實(shí)際顯示的什么。

新人不是應(yīng)該先寫(xiě)個(gè)延時(shí),跑馬燈什么的嗎?
你duang duang一堆那么長(zhǎng)的代碼上來(lái),誰(shuí)能找到問(wèn)題?別人手上都不一定有你用的單片機(jī)型號(hào),也不一定有你手頭上的顯示屏
正確的做法是先寫(xiě)一個(gè)單純的函數(shù),只顯示一個(gè)數(shù)字3之類(lèi)的,只要能顯示一個(gè)數(shù)字了,再改另外一個(gè)數(shù)字燒錄看一下
只要能顯示一個(gè)數(shù)字了,其它功能就慢慢的增加,每增加一個(gè)功能就燒錄驗(yàn)證一次
而不是像你現(xiàn)在這樣,要么是自己先按著自己的想法,一下子把所有的功能都寫(xiě)完
又或者是直接復(fù)制別人的代碼,這改一下,那改一下
然后一燒錄,才發(fā)現(xiàn)不是你想要的效果
