目前在測試IC型顯示器 之前有嘗試過控制並列輸入的顯示器 有成功的控制字碼 今回測試的顯示器為串列輸入 將程式載入後 顯示器並沒有任何的作動產生...= =" 目前不知道是硬體有問題還是軟體出現問題... 所以想請各位大大協助看一下.. 程式碼如下所示 不知道各位大大是否可以替我檢視一下是否軟體部份有問題@@" http://cid-d05d6bff731efcbf.skydrive.live.com/self.aspx/%e6%96%87%e4%bb%b6/ IC-090917.pdf #include <reg51.h> /* define 8051 registers */ #include <stdio.h> /* define I/O functions */ sbit csb = P1^0;
