Design and Development of Micro-meteorological stations based on Raspberry Pi (Windows 10 IoT Core) and iotcore Preface Raspberry Pi (RPi) is designed specifically for Students' Computer Programming education. Only credit card-sized card-type computers can run Linux or Windows 10 IoT Core operating systems. This articl

Setting up Windows Ten for IoT on your Raspberry PiThis week on the BUILD conference in San Francisco Microsoft released the first preview of the Windows IoT (Internet of Thi NGS) for Raspberry Pi 2 (AS-well-lovely devices like the Intel Galileo and Minnowboard Max).First, as I mentioned in February the

-J8 option downloads 8 packages in parallel.Note:the Roslisp package are excluded in these generators because the dependency sbcl are not available in the Raspbian rep Ositories. Building SBCL from source may be possible and is not tested. So far, only these variants has been tested on the Raspberry Pi in Indigo; However, more is defined in REP 131such as robot, perception, etc. Just Change the package path

Cross-compiled Raspberry Pi 2 kernel in CentOS Cross-compilation toolchain in CentOS 6.6 x64 requires glibc-2.14 support (x86 is not needed), so first install the glibc-2.14 Install the relevant compilation tools before installation. Here I will install the entire group directly. Yum groupinstall "Development tools"-y Download the glibc-2.14 source code, compile, install Wget http://ftp.gnu.org/gnu/glibc/gl

To execute this script, you only need to enter the following command line: $ python name_of_this_script.py Below are some samples captured. Small benefits In addition to using the raspistill command line tool to manipulate the raspicam camera module, there are other methods to use. Picamera is a python library tha

Then we can enter the Raspberry Pi intranet IP address on the other host, such as the

Install a lamp environment for Raspberry Pi in the past two days, but there are too many things installed on it, and the default system space is occupied. But the SD card itself is 16 GB. What if I want to extend the Raspberry Pi to a larger space? I can continue to install the software only after the expansion. After

Create a wireless route for Raspberry Pi OpenVPN is a private protocol and requires proprietary clients. Therefore, it is difficult to use OpenVPN on Android (CM9 supports OpenVPN), iOS, and WP8. Combining Raspberry Pi and OpenVPN to build a soft AP can easily solve these pr

ObjectiveIn the previous article, "Raspberry pi set automatic dialing, build no-line by environment" , the author uses HOSTAPD and UDHCPD programs to create wireless hotspots to achieve address assignment and DNS server settings. This article will make improvements to the Raspberry

0. PrefaceWhy do you want to use cross-compilation for "1" The speed at which the cross-compilation tool is developed faster. The Raspberry Pi has already installed the GCC toolchain, which can be compiled directly from the Raspberry Pi source code to generate the executable file. At the same time, the PC can also use
