To telnet to the Raspberry Pi GUI via vnc, the Raspberry Pi must have a VNC Server service installed on one side, and a few simple configurations are required to make the operation more convenient, as detailed steps below.1. Installing the VNC server component--tightvncserversudo Install Tightvncserver2. Set up a VNC p

board, some said to buy the PRC 2706 USB DAV sound card, about 50RMB, investment is not small. Here are 2 proposals Scenario 1, if you bought a Raspberry Pi 3 motherboard bought HDMI VGA interface line, then you are lucky, directly to the HDMI interface to the Raspberry Pi motherboard, HDMI interface powered by the

xtightvncviewer package: sudo apt-get install xtightvncviewer -For other platforms, you can download TightVNC from tightvnc.com. Automation and run at boot (Automatic startup) You can create a simple file on Raspberry Pi and save some commands to run the VNC service. Save the commands so that you do not need to remember them again: -Create a file containing the following shell script: #!/bin/shvncserver :

0 PrefaceThis article describes how to control the Raspberry Pi gpio port through the file IO sysfs. Control gpio through sysfs, first access the/sys/class/gpio directory, write the gpio number to the export file, so that the operation interface of this gpio is exposed from the kernel space to the user space, gpio operation interfaces include ction and value. Direction controls the gpio direction, while val

creates both the top level ~/CATKIN_WS directory and the SRC subdirectory. Note also that we run the catkin_init_workspace command in the SRC directory.Next, even though the current workspace are empty, we run Catkin_make to create some initial directories and setup files. Catkin_make is always run with the top-level Catkin_ws workspace folder (not in the SRC folder):$ cd ~/catkin_ws$ catkin_make$ catkin_make InstallAfter building the new Catkin package, being sure to source the ~/catkin_ws/dev

0. PrefaceThis blog post may not have much use value. But practice for practice. There are many ways to use SQLite on Raspberry Pi, and there are many ways to install it. "1" assumes that Python is used, so you don't have to install SQLite because Python has its own sqlite."2" can be installed using Apt-get. Only the version of SQLite is slightly lower. "3" can be installed using the source code, directly
