40 Gpio on a Raspberry Pi is the best thing to play.They can be directly controlled by c,/c++, Python, Java and other languages.Now, let's see how to do the same thing with node. js.Before you try, install node. js, and move to: 1. Prepare the Test foldermkdir/home/pi/documents/test-gpio-demo/2. Create a file Package.j

First, basic settings 1 sudo raspi-config Move to the fifth "Enable Camera", enter, press the TAB key to switch to "enable" to confirm the return. Back to the main menu, tab to "Finish" to confirm the return. The Raspberry Pi will restart automatically.or execute a command to manually shut down the machine 1 sudo shutdown-h now Warning!!!!!!!!!

In the previous article--Installing the ROS package on the Raspberry Pi, I joined openni2_camera and openni2_launch , if you follow my step by step, compile to a certain step, you will certainly encounter the compilation error, Haha, so I left a last article at the end of the sentence "How to predict the funeral , please listen to tell. "The package that needs to be installed in the previous article needs t

/opt/ros/indigo Common errors: The compilation process compiles more than 180 package and installs it in the/opt/ros/indigo directory, often reporting ' collada_parser ', ' collada_urdf ', ' Rviz ', ' Visualization_ Tutorials ', ' rqt_robot_plugins/rqt_rviz ' these packets are faulty and the installation is interrupted. The solution is to remove the packages from the directory ~/ROS_CATKIN_WS/SRC directory and recompile the entire Ros. Finally, a separate workspace is created and the packages a
