6腳3位數(shù)碼管驅(qū)動程序求幫助

ID:56665 · 發(fā)表于 2019-5-28 15:13

我看到充電器上用的顯示是用6腳3位數(shù)碼管的，誰有這種數(shù)碼管驅(qū)動請傳上來學(xué)習(xí)學(xué)習(xí)。

這是數(shù)碼管的電路圖

已經(jīng)搞好了，方法就是每一位每一段分別掃描，麻煩是有一點，硬件制約，硬件簡單，軟件就麻煩一點。

可以分享下代碼嗎?謝謝!

原理是知道，就是看軟件怎么處理。

也可能有譯碼.6個腳顯示?把那個段去掉了?

這種被叫做 Charlieplexing的方法可以用N個IO驅(qū)動N*(N-1)個LED。

6 個IO 可以驅(qū)動 30 個LED

這種數(shù)碼管是由單片機(jī)I/O口直接驅(qū)動，I/O口要在工作在3態(tài)（高、低電平和高阻），驅(qū)動程序有點復(fù)雜。直接驅(qū)動每一個IO口吧，，沒法省事了

這個是在內(nèi)部將段引腳連接在一起了。一共8個段引腳，3個位引腳。如果是掃描顯示和單個的用法一樣。

如果使用的是掃描顯示，程序完全都一樣，認(rèn)準(zhǔn)管腳就行了。也可以自己寫一段小程序，測定管腳。
每隔3~5秒顯示一個段，a\b\c\d\e\f\g\h,一目了然。

這個帖子有答案
求助：可有認(rèn)識這個小數(shù)碼管的朋友？求資料或驅(qū)動方式 http://www.zg4o1577.cn/bbs/dpj-185110-1.html

7線LED屏陣列如下，其中A,B,C...為LED屏的段，0，1，2.... 表示對應(yīng)的連接IO
參考下圖表，當(dāng)需要點亮某個段時，左邊的拉高，右邊的拉低點亮相應(yīng)位置，
如要點亮1A段，則將0號IO拉高，1號IO拉低，如果我們要顯示一個數(shù)據(jù)，則要依次掃描7個IO
