#文中设置均基于最新版的Raspbian系统2016-Version 11 Raspbian in the desktop environment, the system will go into hibernation after a period of time. Tried some methods such as directly with Xset close DPMS, is not successful. Raspbian uses a lightweight desktop display manager that is LIGHTDM, which allows you to set up Xserver desktop session interaction \ Display, and so on. 1. Open the terminal; 2. Edit/etc/lightdm/lightdm.conf 3. Locate the ' Xserver-command ' in the [Seatdefaults] section, uncomment it,

Raspberry Pi has two audio output modes: hdmi and headphone interfaces. You can switch between the two modes at any time. If your HDMI monitor has a built-in speaker, the audio can be played through the HDMI interface. You can also switch to the headset interface to use the speaker of the headset or other headset interface to play the video. If your monitor requests support from the speaker, the sound is ou

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data is connected to the Gpio (I'm picking up the BCM pin 16th, the physical pin is 36) GND Co

Raspberry Pi-Cron, Crontab (scheduled task), croncrontab Cron is a tool for configuring scheduled tasks in Unix systems. It is used to execute commands or scripts on a regular basis or at a certain interval; the task scope can be to automatically back up the user's home folder every night, or to record CPU information logs every hour. The crontab (cron table) command is used to edit the list of scheduled ta

First, why Choose OpenelecRASPBMC the volume of large functions, the corresponding speed and performance to be weak; Openelec is a lite version, small size function, the corresponding speed and performance have been improved. This depends on our choice, if you like me with multiple sdcard to play Raspberry Pi, then use Openelec as a home Media Center is the most suitable.It is small in size, please refer to
