Sharing internet using Network-Over-USB in BeagleBone Black

Random Codes - Elementz Tech Blog

BeagleBone is a credit card sized computer used as an embedded development hardware known for its reasonable pricing and flexibility in use. Use of Capes make the BBB more acceptable among hobbyist.

BeagleBone_Black

BBB comes with a USB connectivity named USB-Ethernet, by default has 192.168.7.2 as the ip address, which can be used to do Arduino like programming using Cloud9 IDE.

This post is intended to help users to make use of USB networking of BBB to get access to the world of internet by network sharing from the host computer. The main advantage of using this approach is that users can get rid of the need for using long ethernet cables if the router is far away, or only Wifi network is available.

Debian distribution Debian distribution

The Debian OS is used for the testing which is obtained from here.

BBB console can be got by using the following command

Interfacing Relay boards to Arduino

Random Codes - Elementz Tech Blog

This post is intended for beginners to interface relay boards with Arduino. Shown below is the connection details to connect 4 Channel relay board with Arduino. The relays are 12V relays.

RELAY 4_Watermark

The details of the 4 channel relay board is given below.

4Channel Relay_Watermark

• Connect VCC to 12V.
• Inputs 1,2,3 & 4 are used to control the corresponding relays.
• If input is high (5V), then connection is between C (Common) & NO (Normally Open), else connection is between C (Common) & NC (Normally Closed).
• If Input1 is high, LED1 glows and vice versa.
• This board has a ULN driver which gives better performance compared to transistor drive.
• ULN2003 has seven high current Darlington arrays each containing seven open collector Darlington pairs with common emittors.
PS : Make sure to short the ground of 12V and Arduino.

Given below is a sample code to operate the…

Loading Lubuntu OS in CubieTruck

Cubietruck_02

This post is about loading Lubuntu OS in to the Cubietruck board.

We can either use the usual method which involves booting from an SD card,to which the image of the required OS is written. The one explained here involves loading the image directly in to the NAND flash of the cubietruck using LiveSuit (for Linux and Mac users. For windows users PhoenixSuit can be used).

The steps are as described below.

Download image of required OS. The Lubuntu OS is available here

Link : http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct-lubuntu-nand-v1.02/

Install LiveSuit in to the system. The steps for installing livesuit is avilable here: http://linux-sunxi.org/LiveSuit

Press and hold the FEL key and connect the OTG cable (mini USB cable) from PC to the board and wait for the prompt.

Choose suitable option from the dialogue box and wait for the loading process to complete. Do not disconnect the OTG cable inbetween the flashing process.

Once the flashing is complete you can boot the cubietruck from its nand flash. At first it will take a bit long for the sytem to boot. ( Note : These instructions were carried out and tested in LinuxMint 17 and Ubuntu 14.04 LTS. The LiveSuit Didn’t worked well in a 32 bit Linux system it returned some error saying “waiting for Fes device time out”, but worked well in a 64 bit linux System).

BeagleBone Black : Credit-card sized Computer

BeagleBone Black
BeagleBone Black

       BeagleBone Black is a open-hardware, low-cost, low-power, credit-card sized single-board computer with all the capability of desktop machines. Boot Linux in under ten seconds and get started on development in less than five minutes with just a single USB cable. Get your hands in technology’s guts and control your development destiny with these  computers. The BeagleBone Black has evolved out of the long lineage of BeagleBoard products. Current version: a small form-factor, very powerful, and extremely expandable product that allows to create truly innovative projects. The BeagleBoard family was originally designed to provide a relatively low-cost development platform for hobbyists to try out the powerful new system-on-a-chip (SOC) devices that were essentially capable of performing all the duties of a computer on a single chip.
