a single line-of-business application. Windows IoT core runs a universal Windows app and uses the same development, configuration, and management tools as other versions of Windows 10, which makes it easy to integrate into IoT scenarios and leverage existing resources. Raspberry Pi 3B IntroductionThe Raspberry Pi 3B is the third-generation Raspberry Pi, whi

I learned the Linux system with a magic Raspberry Pi board.Raspberry Pi is an ARM-based micro-computer motherboard With a shape of only the size of a credit card. Therefore, it is also known as a new card-type computer. Raspberry Pi has all the basic functions of the computer, but it can be said that it is small and dirty. The Raspberry

Installing the Raspberry Pi is only the first step in making Windows IoT core run on the Raspberry Pi, and the complete set of tools such as management systems are essential. Because Windows IoT core runs on a card PC, there are not too many UI actions set up, and many operations are done through the IoT dashboard app and device portal. Simply tell me how to manage the Windows IoT core on your Raspberry

First, about open source hardwareThe concept of open source hardware is simple to understand that the electronic hardware design detailed parameters are public, such as circuit diagrams, BOM and PCB layout and so on.Main types: Arduino, Cubieboard, Raspberrypi, Pcduino, Beaglebone, Kiwiboard, and MixteilOpen source China Community-Open source hardware zone Http://www.oschina.net/hardwareSecond, choose Raspberry Pi RaspberrypiThe most popular open sour

First, install the Raspberry Pi and Arduino development environment 1, Arduino development environment in the previous article has been explained that the need for friends can see "Arduino Control two motor Movement" this blog post. 2. Building a Raspberry Pi serial communication development environment (1) Install Python: sudo apt-get update sudo apt-get install python (2) Installing a Python gpio module

to the Raspberry Pi, then execute the LSUSB command on the Raspberry Pi, this time the list is connected to all the USB devices, as follows: Bus 005 device 001:id 0000:0000 bus 001 device 001:id 0000:0000 bus 004 device 001:id 0000:0000 bus 003 Dev Ice 001:id 0000:0000 bus 002 device 006:id 15d9:0a37 Bus 002 Device 001:id 0000:0000 I don't know who the printer is at this time. But it doesn't matter, you

Windows 3.1 is running on a Raspberry Pi, and you naturally want to run Windows 10. So you're ready to install a system of Windows IoT core on the Raspberry Pi. When writing this text, it's not the first time that you've installed Windows IoT core. After I got the Raspberry Pi on my birthday, I immediately tried a Windows IoT Core. Support for the official

Recently I used Raspberry Pi to create a Git private server for all my Git repositories. I spent some time to make everything work correctly, but now it can run. Install Git First, install Git on Raspberry Pi.Sudo apt-get install wget git-core This will install the Git server and necessary client software. Install SSH If you have not installed SSH, run the following command to install it:Sudo apt-get install ssh Run the following command to start it:S

Reprint: https://null-byte.wonderhowto.com/how-to/hack-radio-frequencies-hijacking-fm-radio-with-raspberry-pi-wire-0177007/software-defined Radio and Signals intelligence, we learned how to set up a radio listening station T o Find and decode hidden radio signals-just like the hackers who triggered the emergency siren system in Dallas, Texas, Probably did. Now so we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting

echo "Scale=${num}; 4*a (1) "| Bc-lqFor example:echo "scale=5000; 4*a (1) "| Bc-lqThe 4*a (1) is a calculated pi function provided by the BC host, and the scale is the meaning of the BC to calculate a few decimal digits. The greater the scale value, the more accurate the pi is to be calculated,The more time you use it, the more time you'll spend! This can be used

What's this?"Roomblock" is a robot platform consists of a Roomba, a Raspberry Pi 2, a laser sensor (RPLIDAR) and a mobile battery.The mounting frame can be made by 3D printers. ROS navigation system enable to make a maps of rooms and use it to reach to the goal autonomously.Who need this?Anyone want to learn the cutting-edge technologies of robotic navigation, mapping, and autonomous driving.
