Raspberry Pi is not like the motherboard of the PC with a battery for the timing after the shutdown, each time the board starts to re-time, netizens generally provide the method is to use the Ntpdate network calibration, but the board is not even mobile network, because the mobile firewall will intercept the relevant a
Guide to Getting StartedNow let's connect the LEDs to the hardware devices that have WINDOWS10 IoT Core installed and create an application to make them blink.Load a project in Visual StudioHere we find the routines here, which are available in C + + and C # versions. This tutorial only covers versions that use C #. Copy the project folder to disk and open it in Visual Studio.Then check your Windows IoT dev
first, the simplest method on the Raspberry Pi is to use apt-get and then give control to the Openhab user.sudo apt-get install openhab-addon-binding--hr Openhab:openhab/usr/share/openhabNext, you need to tell Openhab to load the binding and configure all the required variables. go to the configuration folder, copy a copy of Openhab-default.cfg, and name it openhab.cfg. Open the file, search for hue, and r
Raspberry PI board because the cost is not add wireless module, do not want to be bound by the network cable, we need to own a USB wireless module. When buying the board, see the official recommended Edup wireless card, the price is appropriate, directly started.Using REALTEK8188 chip, 802.11n, transmission speed 150Mb
Although the Raspberry Pi has gcc, you can compile the C + + program, but if the project is large, compiling with the Raspberry Pi will waste a lot of time, we can compile the program on the PC, then pass the executable file to the Raspb
downside is that no matter how big your card is, its partitioning depends on the operating system, which wastes some space. The command is as follows: DD if=raspybin bs=1kb count=4000 of=/dev/sdxx here xx is your SD card, don't make a mistake! Otherwise lose hard drive data at your own risk. I purchased a 8G SD card, after installing the raspybin image of Pi, insert the SD card slot, connect the mouse, keyboard and HDMI to power up. The firs
Today to change the play, do not continue to explore Raspbian system, research on the official website recommended another method of installation noobs.So what is noobs? It is an operating system management tool designed for easy-to-use graphical interfaces built for Raspberry Pi.

Canonical urges the user to install the Linux-image-4.13.0-1015-raspi2-4.13.0-1015.16 kernel as soon as possible so that his linux-raspi2 kernel package can be patched for the Raspberry Pi 2 board computer on Ubuntu 17.10 systems and is now available from the main Ubuntu software repository.

Yesterday my wife read the Rpi.gpio document, one hours and dozens of lines of code can be achieved by the Raspberry Pi car through the infrared detector tracking operation. It's something that no other language can do or that's hard to do.

It is important that you do not need to configure any environment for development (the Linux system provides its own interpreter + vi editing ). I have a hard time learning python. I use PyRaspberry Pi Documentation.
