51單片機—8*8LED點陣—09—①

今天這個就是簡單的控制8*8LED點陣亮0~F這16個數字，暫時不加左移啊~~，上移啊~~以及16*16的點陣呢~~

不過也就這些天都發出來吧~~

呵呵~~

8*8LED點陣顯示0~F（這里是靜態顯示）

注意：

用Proteus仿真開始還真的不知道那個是行，那個是列~~

還得浪費我時間一點點看人家別人的東東~~

1）紅色LED上邊為列，下邊為行（其它顏色的正好相反，上為行，下為列~~）

2）對于紅色來說，上邊的列最低位在最右邊；下邊的行最低位也是恰好相反，在最左邊（一會看圖就知道了，我的就寫反了~~正好可以反過來看了~~）

基本上就這么兩點的注意事項~~

然后就是程序了：

LED.c
