最近在写论文加上出去玩了一圈所以停更了一段时间。上次咱们GPS有个室内用不了的问题,咱们看看咋解决一下。

之前给老师看了下ui,老师说字太小了所以这次我优化了一下可以通过全局变量控制。
这次够大了吧
这里可以控制大小设定了
client添加GPS分析
接收到的数据只有成功和失败两种,但是发送的话我设置了两种模式direct和memory。
direct: 这种模式是直接启动GPS读取实际的数据,但是我们室内肯定用不了GPS哇。于是就加个读取存储器的默认值。
memory:这个模式就是直接读取存储器的默认值
GPS的命令不多所以两种模式共用一个设备号
完善服务器网络通讯部分代码
这块就比较简单了,基本和以前的没啥区别。后面这里要整合一下抽象出一个函数来。可以缩小代码体积。
添加GPS的BSW层

大部分内容沿用了韦东山老师的代码,在外层封装了个任务判断而已。

我直接拿韦东山老师的代码过来用了,这些代码都比较简单,就是打开串口设置串口读取数据和数据处理。严格来说韦东山老师也是仿照linux源码的驱动程序写的。在国外引用思想也要表明。但是国内版权意识比较差这里也没要求。如果严格实施的话估计全世界都成为GPL的天下了哈哈。
