[Fireduino试用体验] 实验一 开发平台和测试驱显
开发平台的创建着实费了不少功夫，下载所有说明、资料、开发软件等而后学习了一下，感觉差不多了直接展开Arduino1.6.8这款开发软件，感觉以前玩过328芯片应该没有问题，就直接上以前编译通过了的LCD0713黑白显示屏，结果发现问题多多。按照其他开发板的经验，连接上USB应该出现什么未知设备之类的警告，余下的就是八仙过海了，结果什么都没有发生——自认为，此USB就是供电用的，于是按照以前的方法，招了一个AVRAsp下载器按照图示连接好线，结果他根本不认这个下载器，报错为：Upgrade failed:No found any rockusb device,please plug device in!就是说，这个开发板需要rockusb device设备下载，但无论怎么操作死活没有这么个设备出现，于是马上在“Firefly小分队”发帖求助，很不错，这个聊天群很棒很快就有了响应，按照网友的帖子，我是从安全模式安装的驱动——安全模式是最简单好用的，并且支持所有无法安装驱动的终极手段。回到正常模式之后，插上USB线，还是没有出现？！于是尝试着重新按Reset和UpGrade两个键，松开手后设备出现了，但有个小问号，没有理会，直接下载程序，一切Ok。无意间看设备管理器，哪个rockusb device有没有了？！经过多次实验，得出的结果是下载时双按两个键，出现rockusb device下载，按Reset键运行程序后，哪个rockusb device就有隐退了——真是短命皇帝。不过不影响编程下载就可以了。不知你们也是这样吗？见照片10，11。
下边开始编程，以前做过LCD0713的程序，直接拿来，为了省事，写了一个0713.h的函数放在主函数的文件夹中，代码如下：

上述代码可以实现1路程序计数器、2路ADC，已设置、2路PWM、为了省事先删除了、还有1路测试超声传感器测距的，也删除了。结果见照片12。
结论：除了下载时需要双按键出现Rockusb之外，其他的还可以。只要能采用Arduino的方法来编程就是简单易上手。以后的就可以抽空实验了。
