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

The start is quite smooth, the first use of the people on the Internet streamlined OS, found that the act and the PWR lamp has been on, internet access to say with HDMI to connect the display needs to modify the configuration file Config.txt, but the situation is still unchanged.If you still use the official system to try it, the internet search for the last 2015 years (feel should not be the latest, first try, no more brush also minutes of things, who call us so love toss it): Http://pan.baidu.

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. PYTHON Python is a wonderful and powerful programming language that's easy to use (easy to read and write) and with

Use SFTP to manage files on Raspberry Pi SFTP (SSH File Transfer Protocol) is a network protocol that provides SSH-based file access, file transfer, and file management methods. With SFTP, you can easily modify, browse, and edit files on Raspberry Pi. SFTP is easier to configure than FTP, because Raspbian has enabled

developers need to build an art-level graphical user interface. QT is easy to scale and allows for real component programming. Basically, Qt is the same type of thing as the MOTIF,OPENWIN,GTK on the X Window and the Mfc,owl,vcl,atl on the Windows platform.To put it simply, QT can write programs that are easily ported to other platforms, basically recompiling the program.install qt on Raspberry PiInstall using the following commandsudo apt-get install
