這程式碼的用意是把 arduino 上面超聲波的值用介面顯示的方式顯示出來，但是遇到進度是相關程式碼找到了，ＪＡＶＡ相關控制ＰＯＲＴ的ＪＤＫ也裝了。而當我ＲＵＮ的時候它顯示了Error loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.pathCaught java.lang.UnsatisfiedLinkError: com.sun.comm.SolarisDriver.readRegistrySerial(Ljava/util/Vector;Ljava/lang/String;)I while loading driver com.sun.comm.SolarisDriverError loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.pathCaught java.lang.UnsatisfiedLinkError: com.sun.comm.SolarisDriver.readRegistrySerial(Ljava/util/Vector;Ljava/lang/String;)I while loading driver com.sun.comm.SolarisDriver

新的工作是我的資料只要傳到 com port 即可 !接下來三軸的值也比照這個工作為主，接下來的三軸值的誤差值還在測試中。

接資料的部分和藍芽配合 !

最後我發現我的錯誤是下面的訊息應該是相關的 Library 未載入 !

(Project-Property-Library 內設定 )

下面程式是藍芽接收端的程式碼，主要是藉由 commport 來做自動接收的動作，程式碼上有問題再解決
