An Android weather project source code, using the API provided by Baidu, has the basic functions of weather query, city settings, Short Message Sharing weather, the interface is refreshing, but now because of Baidu key failure, can not update the weather. The code has more detailed comments. Code volume is not large, interested friends can check it by themselves.

说明：  动态压缩感知（DSC）是压缩感知领域中一个重要的研究分支，它是近几年新兴起的一种信号处理与分析方法，与传统的压缩感知理论不同，DSC研究的对象是稀疏时变信号，并且已在视频信号处理和动态核磁共振成像等方面显示出了强大的应用潜力。本节正是在此基础上，提出了一种用于多普勒频率跟踪估计的DSC方法。首先，通过前一跟踪时刻所得到的先验DOA稀疏信息，获得当前跟踪时刻信号向量中各位置非零元素的分布概率，继而建立起动态DOA的稀疏概率模型。然后，采用加权l_1范数最小化方法重构出当前跟踪时刻的信号向量，从而确定非零元素的位置，获得DOA的实时估计值，最终实现运动目标的动态DOA跟踪。(L1 norm deals with DOA estimation)

通过sparten2来实现数字电压表实验。实验板上的数码管显示模拟电压的数字，调整实验板上的控制模拟电压的电位器，显示模拟电压的数字应该能够随输入的电压变化而变化。-Sparten2 to achieve through the digital voltmeter experiment. Experiment on-board digital tube display the number of analog voltage to adjust the control experiment on-board analog voltage potentiometer, showing the number of analog voltage input voltage should be able to change with the change.
