老外最近很忙做 DDS, 可是提出了一個非常差的 IDEA.


他需要用 BCD 輸出的 THUMB SWITCH 加上 LED 顯示, 設定 DDS 的頻率. 雖然完全不知道何為 DDS, 不過這樣的工作並不需要那麼複雜.

手上有了自製的 Arduino, 還有人家設計好的 LCD 顯示, 只要組合起來就好了, 連代碼都不用寫. 實驗了 Arduino 兩個基本的顯示 LCD 顯示.

LCD 16x2 接腳及基本, 溫習這個, http://hk.myblog.yahoo.com/xiao-laba/article?mid=2177
自製的 Arduino, 溫習這個, http://hk.myblog.yahoo.com/xiao-laba/article?mid=1556


下面是參考用的記錄

1) LiduidCrytal Library, 0016 版本自帶, 連線用 4BIT, 除了 Hello World, 其他功能有 BUG, 不能用




2) 網上參考了人家的經驗, 看到了 LCD4Bit Library, 使用很好, 15分鐘完畢
