數控烙鐵單片機程序求指點燒錄后數碼管是全顯

ID:348282 · 發表于 2018-10-10 21:01

自學單片機有一段時間了，做了款數控烙鐵程序，其中大部份程序我先屏蔽，先搞顯示正常，發現燒錄后數碼管是全顯，顯示不正常不是讀取AD的數值，用K型熱電偶作探頭經放大100倍送AD轉換，DC5V/2A供電，請大神們指點下。程序如下：

還有就是delay5ms()延時函數那里編譯出警告，顯示子程序好像沒起作用。

嗯，還有顯示子程序好像不起作用，如延時函數那里，我把它屏蔽了，編譯時少了幾個警告，可能少了聲明函數，但不知在那里聲明。

你的顯示程序寫得很混亂，從位碼看是用的共陽數碼管，從段碼看是用的共陰數碼管并且也沒有按a~f順序編碼，不知道你的段碼數組依據什么來的。
