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

write down what people say, and convert it into words. "Thinking" is to give different outputs based on different inputs. For example, the other person said "now time", you can answer "now is Beijing time xx point xx points." "To say" is to convert the text into speech and play it out. These three parts involve a lot of speech recognition, speech synthesis, artificial intelligence and other technologies, these are to spend a lot of time and effort t

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

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
