深圳德卡D3-U讀寫卡器windows(Java)，linux(C)驅動開發

一、windows32(Java語言)驅動開發

1.1、檔案用途

在D3的Java檔案夾下有檔案夾兩個：classpackage、example，檔案一個：readme.txt。

classpackage中的 javaRD800.dll 是一個面向Java JNI 的windows動態連結程式庫。

classpackage中的 javaRD800.java 是一個面向Java的 JNI 介面。

example中的javaRD800Demo.java 是一個使用Java編寫的 讀寫卡器測試程式。

調用的順序如下：

javaRD800Demo.java---> javaRD800.java---> javaRD800.dll

1.2、動手測試

在 Eclipse 中建立一個 Java 工程，javaRD800Demo.java、javaRD800.java 放在 src 檔案夾內，javaRD800.dll 放在工程根目錄下。

編譯成功！

運行出錯！提示找不到依賴的類庫。

1.3、分析、解決問題

估計是缺少dll檔案，下載 dll檔案依賴查看器 發現缺少 dcrf32.DLL 檔案。

這個檔案 Java 檔案夾裡面沒有這個檔案，可以在 D3--->win32-dll目錄下找到此檔案，拷貝此檔案到工程根目錄下。

調用的順序如下：

javaRD800Demo.java---> javaRD800.java---> javaRD800.dll---> dcrf32.dll

編譯成功！

運行成功！

二、Linux_x86(C語言)驅動開發(Ubuntu_12.04 以下操作請 sudo -s 後進行)

2.1、先安裝 libusb 相關類庫

sudo apt-get install libusb*

2.2、查看系統預設類路徑

vim /etc/ld.so.conf

顯示：

include /etc/ld.so.conf.d/*.conf

cd /etc/ld.so.conf.d/

ls

顯示：

i386-linux-gnu_GL.conf  libc.conf    x86_64-linux-gnu_GL.confi686-linux-gnu.conf     oracle.conf

vim libc.conf

顯示：

# libc default configuration/usr/local/lib

說明系統預設類庫路徑有一條 /usr/local/lib
 

2.3、拷貝檔案

拷貝 librf.so 到 /usr/local/lib，拷貝librf.h 到 /usr/local/include

2.4、更新系統類別庫

#ldconfig

2.5、在Eclipse cpp中建立一個C工程

拷貝 RfDemo_linux.c 到原始碼檔案夾 src；

拷貝靜態連結庫檔案 D8U.a、libusb-1.0.a
到工程根目錄下；

2.6、配置Eclipse cpp 開發環境

2.6.1、使用C99編譯標準：右鍵點擊項目->Properties->C/C++ Build -> Settings -> Tool Settings -> GCC C Complier -> Miscellaneous

在 "Other flags" 中追加 -std=c99；

2.6.2、添加使用的動態類庫：右鍵點擊項目->Properties->C/C++ Build -> Settings ->
Tool Settings -> GCC C linker -> Libraries

在 "Libraries" 中添加 rf、rt、usb、pthread

2.6.3、添加使用的靜態類庫：右鍵點擊項目->Properties->C/C++
Build -> Settings -> Tool Settings -> GCC C
linker -> Miscellaneous

在 "Other objects" 中添加工程根目錄下的 D8U.a、libusb-1.0.a

2.7、完成

編譯成功！

運行成功！
