raspberry pi terminal emulator

software, you need to include the sudo command prefix before the agt-get command:sudo apt-get update.See a lot of other apt command information.You can also use the sudo su command to execute a Super User shell terminal. Once the command is executed as Superuser, there is nothing to prevent the system from damaging the error. The equivalent of shutting down the security on the machine. Although this makes it easier to access things inside the system,

compile the correct executable file on the Raspberry Pi.2. Compiling third-party librariesIf you want to set the global cc and CXX variables, enter the following command each time you open a new Terminal :1 $export cc=arm-linux-gnueabihf-gcc 2$exportThe other global variables are the same as above.Cross-compiling steps with the following common third-party libr

When you log on to Raspberry Pi and open a terminal window, or you replace the graphic user interface and start directly to command line mode, you will start in the home directory. If your user name is Pi, the path is/Home/PI. This is where the user saves the user's own fil

Python implements the example code of Raspberry Pi WiFi disconnection automatic reconnection, pythonwifi Enable Automatic reconnection of Wi-Fi disconnection. The principle is to use Python to monitor whether the network is disconnected. If the network is disconnected, restart the network service. 1. Put the Python code autowifi. py in the/home/pi directory: #

The simplest of a Raspberry Pi Gpio operation Getting started, here is a record of the followingFirst on the connection diagram:Horizontal slots. Figure Akzent The BigUsing the Gpio gnd and #18 pins, this is not, the red wire is 18 pins, the dark line is the GND pin, the following Python code:1 #Coding:utf-82 ImportGpi.gpio as GPIO3 Import Time4 5 Gpio.setmode (GPIO).

value is-1, 0, it indicates timeout, and 1 indicates successful interruption. Before calling this function, we need to initialize gpio. For example, we want to set gpio 0 to wait for the disconnection of the descent edge: We need to run gpio edge 0 falling on the terminal before running the program. 2. Int wiringpiisr (INT pin, int edgetype, void (* function) (void )); This function uses a function as a parameter to obtain the interrupt at a
