水果做键盘控制跑跑卡丁车

视频地址:http://v.youku.com/v_show/id_XODkxMDQwMzU2.htm

操作系统:WIN8 64 位

需要rxtx jar包的支持,我的是64位,32位的百度下载.

rxtx jar包(64位)下载地址:

懒得复制粘贴,直接下载代码文件:http://download.csdn.net/detail/h_hongchang/8440181

使用方法:

1.修改 上位机界面类(SerialCorrespondenceClient)里面的 COMS 变量为你当前arduino的串口;

2.运行界面:

点击"开启监听",

硬件:arduino uno3,连线方式根据代码上调整就好,当然也可以自己定义,不影响上位机.

上位机使用java语言编写,界面功能很简单.类中很多方法没有使用到,是为以后扩展功能留存的.着急回家过年没怎么好好整理代码,大家可以改进.添加新功能.灵敏度稍欠缺,过年回来再优化吧.

有三个类文件:

1.上位机界面;

2.串口通信监听;

3.模拟键盘按键工具类.

1.上位机界面代码:
