步骤1:您需要的内容:
硬件:
LattePanda(您可以
屏幕和触摸面板
软件
Arduino IDE
Visual Studio
步骤2:演示1:检测鼠标位置并单击事件
让我们执行项目步骤一步一步首先,请尝试检测是否按下了鼠标。因此,我们可以根据间隔来检测双击和三次单击。
这是一个简单的Windows Form应用程序。文本框将显示鼠标的X轴和Y轴。 您可以在PC上播放此演示。
操作方法播放演示1:
运行.exe并移动鼠标,软件将自动检测鼠标的位置。如果按下鼠标左键,文本框将显示该事件。
您可以在下面查看代码或在此处下载演示。如果要自己制作此演示,则需要在此处下载Visual Studio。 Open.sln文件,然后可以将其设置为自己的文件。

步骤3:演示2:检测双击并控制LED
请参见上图。为了防止错误触发,我在屏幕区域的右1/5处设置了检测鼠标双击的功能。
在此演示中,您将知道如何检测双击(只需计算两次单击的间隔)并通过Arduino Leonardo控制LED。
此演示涉及C#和Arduino串行通信(PC与Arduino之间的通信)。如果您想了解这部分知识,请参见此处的教程。
如何播放演示2:
双击右侧1/5侧面屏幕上的,然后您将进入GPIO控制模式,LED将会点亮。单击屏幕左侧的4/5侧,LED将关闭。
您可以在附件中查看代码或在此处下载演示。如果最小化窗口,则该功能仍然有效。很酷,不是吗?

这是一种进行交互项目的新方法。它也可以用于家庭自动化控制系统。使用PC来控制空调,灯光,电视等。
步骤4:演示3:检测三次单击并控制屏幕背景光
在此演示中,您将获得鼠标的位置并将实时值发送到PC。然后,您的PC可以根据该值更改背景光。 您还可以在PC上播放此演示。
此演示涉及使用C#来控制屏幕的背景光。如果您想了解这一部分知识,可以在这里查看教程。
如何播放演示3:
在右侧1/3上单击三次。屏幕的5侧,然后您将进入GPIO控制模式,向上或向下移动手指,屏幕的背景光会变暗或变暗。
此功能与您的iPhone有点相似。您可以在附件中查看代码或在此处下载演示。

步骤5:演示4:检测三次单击并控制LED灯
在此演示中,您将获得鼠标的位置并将实时值发送到Arduino。然后您的Arduino可以根据该值控制LED。
播放DEMO 4的方法:
在屏幕右侧的1/5上单击三下,您将进入GPIO控制模式,移动您的GPIO手指向上或向下,LED(D13)会变亮或变暗。
此演示涉及PC与Arduino之间的通信(Arduino和C#通信)。如果您想了解这部分知识,请参阅此处的教程。
您可以在附件中查看代码,也可以在此处下载演示。

步骤6:摘要:
您得到的货款!在Respberry Pi上运行Win10时,我不能忍受滞后。当您需要在SBC及其基于x64的处理器上进行大型项目时,LattePanda是一个不错的选择。 LattePanda的CPU可以完美地处理大型项目。它也可以完美地运行Ubuntu。对我来说,LattePanda是一个训练我的编码能力的好平台。由于它运行Win10系统,因此我可以使用Visual Studio在C ++,C#,Python等中执行许多项目。更重要的是,它还配备了Arduino Leonardo。我可以在PC上轻松控制物理世界。
