This blog will show you how to install three different text-based Web browsers on Raspberry Pi. The original article can be found here or at the bottom of this article. Most Web browsers run a little hard on the small school, or consume a lot of resources, so an alternative solution is to use a web browser based on command line. So far, text-based browsers have not been able to do anything that a common bro

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

The hand has a CCD Camera (Barcode reader/scanner Module), it is through RS232 communication, with the RS232 to the USB adapter to connect the Raspberry Pi, you can complete the hardware connection. For serial communication, it can be realized by pyserial.First, install Pyserial:Download the latest version of the installation package from Https://pypi.python.org/pypi/pyserial and complete the installation w

Raspberry Pi brought a network port (eth0), I bought a edup 8188CUS Junk wireless network card (said it garbage because the default can not start the listening mode, to recompile the kernel, very frustrating)Eth0 Port I want it to connect to the Intranet 1 (192.168.2.0)Wlan1 Port I want it to connect to the Intranet 2 (192.168.1.0)This is how you configure the/et

Raspberrypi can toss a lot of methods, I will be my own toss experience to share with you. As a wireless router, we need to provide DHCP function and wireless AP capabilities, we respectively through the Isc-dhcp-server and HOSTAPD the two software to achieve, inter-card forwarding directly through the iptables definition of NAT rules to achieve. Install DHCP service and AP hotspot Service [python]apt-get Install isc-dhcp-server apt-get install HOSTAPD Modify/etc/ network/interfaces Add Modi

I encountered a problem yesterday, my raspberrypi has entered emergency mode after I plug out the power cord directly, I searched in the internet, it said need to check the file system because of power loss, I used ckfs and e2fsck command to fix the partition, but it still doesn't work, I found that it shows "a start job is running for dev-sda1.device" and timed out. I searched the problems, it said thatSolution:Cause: the swap partition ID is not fou

Reference: RPi Serial ConnectionThis article from: Http://www.raspberry-projects.com/pi/programming-in-c/uart-serial-port/using-the-uartUsing the UARTIf you is running Raspbian or similar then the UART would be used as a serial console. Using a suitable cable, such as the Ttl-232r-3v3-we, you can connect it to your PC and using some simple terminal software Set to 115200-8-n-1 use the command line interface to the

Raspberry Pi wireless routers there are a lot of ways RaspberryPi can do. I will share my experience with you. As a wireless router, we need to provide dhcp and Wireless AP capabilities through the isc-dhcp-server and hostapd software, forwarding between NICS is directly implemented through iptables defining nat rules. Install dhcp service and ap hotspot service [python] apt-get install isc-dhcp-server apt-

Because our campus network can be connected to the Internet only through web page authentication, it is really difficult for me to do this only for those who have no GUI on the command line. I want to write a script in Python to automatically fill in the form, and then post it. Later I found that Linux has a curl command, and Raspberry Pi has been installed by default (My ubuntu10.04 does not exist ). Now,
