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.

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
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

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

Time: 5 minutes
Install the flight control part (Raspberry Pi Zero + PXFmini) and connect the jst gh line to the power module and PXFmini on the drone. In this way, the power can be supplied to the flight control part.
Next, you need to install the PWM modulation in the flight control system, connect your ESC

sudo apt-get install xtightvncviewer
-For other platforms, you can download TightVNC from tightvnc.com.

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:
