HC-04是树莓派上用的比较广泛的超声波传感器，可以用来测量设备和物体之间的距离。可惜网上的资料很少有针对Windows 10的，几乎都是Python和C在Linux上的例子。 hackster.io上有一篇用HC-04做雷达的例子，但是设计的部件太多了，对单纯学习HC-04传感器的使用来说这个例子比较复杂。搜了一圈，英文资料最好的是这篇：http://www.guruumeditation.net/en/digital-io-with-windows-10-iot-raspberry-pi-2-and-the-ultrasonic-ranging-module-hc-sr04/ 国内中文资料介绍Windows 10上HC-04传感器的文章似乎还没有，所以就简单总结一下步骤。 一、物理连接 对于没有多少物理和电子知识基础的人（比如我）来说，第一步连线是比较难的。很多文章都一笔带过说“这很 …
I bought a moisture sensor like this recently. After some research, there seem no articles to indicate how to use it in Windows 10. So I figured out myself. This sensor has 4 Pins, which are: PIN Usage AO Analog Out DO Digital Out GND Ground VCC Power So, let's connect VCC to DC3.3v on RPi, I use PIN 01. Connect GND to any ground header, which I use …
I purchased a GY-30 light sensor recently, this model is also known as "BH1550FVI". There seems no sample for this sensor on Windows 10 yet, so I tried to make one. The light sensor looks like this: My board is a Raspberry Pi 3, the GPIO layout is shown in this table: Because GY-30 is an I2C device, so we can not use GPIO to drive it directly, we must use the I2C ports. In addition, …
UWP通常是没有让设备关机和重启的权限的。但是在Windows 10 IoT Core中是有办法实现的。安装Windows 10 Iot Core之后默认启动的那个欢迎页面右上角是有关机和重启按钮的。其实就是个UWP，它的源代码在：https://github.com/ms-iot/samples/tree/develop/IoTCoreDefaultApp 分析源代码可以发现，关机和重启是通过ShutDownManager这个class实现的。 #region Assembly Windows.System.SystemManagementContract, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime // C:\Program Files (x86)\ …
For those who have watched the "Big Bang Theory", you would probably remember that those physicists build an Internet controlled lamp. The signal send from their laptop traveled around the world and come back to their house to light up the lamp. Now, with Windows 10 IoT Core and Microsoft Azure, we could also achieve the same thing on a Raspberry Pi 3. First, I strongly recommend you to read …
