Using gstreamer with Raspberry pi 0

March 7th, 2017

Gstreamer is an application which provides video streams  without latency. It can be helpful in streaming video from raspberry pi to windows without latency. It supports all major operating system like Windows,MAC,LINUX. It has support for color and interlaced videos. It works fine if it is set up at both ends like from raspberry pi end and windows end. It helps when you want to stream videos from Raspberry to your computer without latency.

Setting gstreamer on Raspberry

  • You need to edit the sources.list file so enter:

 

                            sudo nano /etc/apt/sources.list

                   and add the following to the end of the file:

   

                         deb http://vontaene.de/raspbian-updates/ . main

               Press CTRL+X to save and exit

  • Now run an update (which will make use of the line just added):

 

                               sudo apt-get update

 

  • Now install gstreamer on Raspberry

 

                        sudo apt-get install gstreamer1.0

Features

  • High performance and low latency
  • Maintains quality of service when high CPU load.
  • Gstream API's can be accessed through various programming languages.

Video Streaming

Through gstreamer you can also stream video from pie to pie.  It provides platform to create various applications like video editors, media players etc. After installing gstreamer on raspberry you to have create .sh file .  The below picture shows  .sh file content.  #!/bin/bash  tells script to use bash integrator,then you copy script from my videos description. Make sure you make .sh file excutable by editing its properties.

Simmilary you can install gstreamer on windows by downloading its files. and then run to install and then create a .bat file with content from my videos description.

  • Run .sh file from Raspberry pie to send video streams and also run .bat file on windows to receive video streams.

The good news is that Latest versions of Raspberry pie comes with gstreamer  installed. Hope this helps

Connecting Raspberry pi 0 using WinSCP

March 7th, 2017

The topic deals with Raspberry pi using WinSCP. Let us understand what is WinSCP. WinSCP is a opensource software which is used to transfer files from local computer to remote computer. WiSCP supports windows operating system.

Features

  • All common file operation
  • GUI
  • Text editor
  • Remote editor.
  • Supports public key authentication
  • Supports SCP,SFTP protocols

Functionality

  • Can access entire directory of remote computer
  • Capable of transferring gaming files
  • Can drag and drop files from host to remote computer or vice versa.

 

Now let's understand how we can use WinSCP to connect to Raspberry pi from host computer.

  • Download WinSCP application file. Its comes in zipped file ,just extract file and you can view your application file, if  you get confused the biggest size file is your application file.
  • Now connect your raspberry pie to your home network using network cable also if you don't have ip address of Raspberry pie you can connect it to your computer and get IP address using command sudo ifconfig from command line. If you know ip address skip this.

ip

 

  • Now run WinSCP application on your local computer, a box opens which asks for details like file protocol,hostname,username,password,port number.

Provide file protocol as SFTP, Host name or IP address of Raspberry, username and password of Raspberry, provide port number as 22 and login, you will be connected to your Raspberry pi and you can perform all common file operations, you can view entire directory tree structure, Drag and drop files. You can edit files with text editor. When you click file in remote file manager it is transferred to local machine, then you may edit file hence used as remote editor. you can also use local editing tools if you want and when document is saved remote version is updated automatically. So this is great application, hope it helps.

Bootable SD Card for Raspberry pi 0

March 7th, 2017

This topic deals with how to prepare SD card for Raspberry pi 0 on windows operating system.  It requires obviously a SD card and two important things.

  1. image file
  2. win32diskimager application. Its is an application that writes CD/DVD image files to SD card, creating virtual disk drive.

STEPS:-

1. Go to raspberrypi.org/downloads ,and download the operating system image file and win32diskimager application. For image file you can have standard operating system Raspberry  "WHEEZY" image file from raspberry.org. and  win32diskimager can be downloaded in the same way as you can't copy directly your image file to SD card. The below picture shows this step clearly.

2. Insert your SD card in to your computer. it takes few seconds to appear as your removable disk drive.

3.Downloaded file are zipped files ,so extract the two downloaded files and you will see a operating system image file(.img) and win32diskimager.exe file. Now Run your win32diskimager.exe file ,you may try "RUN AS ADMINISTRATOR"  ,a box opens shown below after few seconds.

new1

Browse your image(.img)  file and select your removable drive for SD card. and then click "write" as shown below.  vv

Then you will get a confirmation box ,if you continue writing, you can click "yes" . Make sure you select correct drive to copy your image file. It takes few minutes to copy your .img file to your SD card.

4.After "SUCCESS" message remove your SD card and plug into your raspberry pi 0 and check. Make sure SD card connection is not loose to your raspberry pi 0.

5.You can also copy your image file from one SD card to another. Just follow the above steps and click "Read" for current SD card then unplug current SD card and plug new SD card ,click run win32diskimager ,select your image file, drive and click "Write" . The image file will be written to your new SD card.

Thus you can boot up your Raspberry pi using your SD card on Windows operating systems like XP.7 ,Vista or 8. Hope this is helpful.

Notixed Kickstarted shipping update 3/2/2017

March 2nd, 2017

As some of you may have already noticed in your incoming message, the shipping of Notixed has started, and it should be in the hands of few of you this week end.

More specifically, we have already shipped out the single Notixed to US as well out of US backers. We have packaged shipment for the remaining backers and these will ship through this weekend. By Monday we expect to ship to all of the backers.

International backers should allow three weeks before contacting us for non receipt of the unit.

We had some bad experience with the shipment of our previous HubPiWi Blue project and we had more than complaint about the non arrival of the units. This had happened because one of the packets (that had about 50 boxes) that was supposed to be shipped to our drop shipper in UK, was lost.

We are taking special care this time and we expect that the complaint will be fairly less.

We once again than everyone who supported and backed Notixed.

One last thing - the newer Raspberry Pi Zero W has arrived. We also ordered one but have not received yet. However, we have checked the images of the Bottom side of the PCB and it looks like they have not changed the location of the test points. So the good news is that the Notixed should work on the Raspberry Pi Zero W. If anyone can confirm this - it will be great.

March 1st, 2017

I received an email from Jay Fallah who reported the procedure to update the Raspbian 2017-1-11 lite to make it work with the HubPiWi Blue. I am just reproducing the steps.

Down the latest raspbian 2017-1-11 lite version
got the ssh running and ssh’d to it.

installed cmake, git, build-essential

installed linux-headers-4.4.0
installed raspberrypi-kernel-headers

downloaded driver package
git clone https://github.com/lwfinger/rtl8723bu

changed Makefile
sed -i 's/EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE/#EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE/g' ~/rtl8723bu/Makefile

changed to folder rtl8723bu
make
sudo make install

Reboot

He has also reproduced the video of the steps that can be seen here.

I have not verified it. If someone can verify this and let us know in the comment that will be great.

Raspberry Pi Zero W - Includes Wifi and Bluetooth

February 28th, 2017

Yesterday, we saw the launch of Raspberry Pi Zero W, the integrated Wifi and Bluetooth in the same board. The price has been increased from $5 to $10. With this integration the Pi Zero becomes more useful and you can do many more things with it.

RaspberryPiZero-W

Availability

The Pi Zero availability is suffering from the same availability issue as the Raspberry Pi Zero at the launch. When we checked at different websites for it on 2/28/2017 at 8:00 AM, it was out of stock on all websites. These are however being sold as an add on which Pi Hut says "Raspberry Pi Zero W with essential kit".

USB Hub Still missing

The one components still missing with Pi Zero W is the USB Hub. All you have a only a single Micro USB Connector. Possibly once you set up a Bluetooth Keyboard and Mouse you should be good to go. However, if you wish to hook a USB based Keyboard or a mouse, you are out of luck.

How it impacts the Reference Designer Add on Boards

Reference Designer Add on boards Hubpixed, HubPiWi and HubPiWi Blue were designed to mate with the Test Points available on the rear of the Pi Zero. The newer version of the Pi Zero still seems to have the Test Points, but its position might have changed. We will know it for sure when we get the samples in our hands. The HubPiWi and HubPiWi Blue will gradually be phased out, as with the Wifi and Bluetooth are already included in the newer Pi Zero W. A newer version of the Hubpixed that we will call as HubPixed W - will be designed and will be made available in about 3 weeks.

If you already have the Raspberry Pi 1.3 version, you can make it useful by purchasing Hubpixed, HubPiWi or the HubPiWi Blue. If you have purchased or are planning to purchase the Pi Zero W - you may want to wait for the release of the Hubpixed W to make these more useful.

We welcome the launch of the Pi Zero W - the only missing thing in it is the integrated USB Hub. The Pi Zero may want to integrate the USB and make this product more useful.

Antenna

The rear side of the board says -"Uses Antenna technology Licensed from Proant AB". The rear side also includes its FCC ID - 2ABCB - RPI0W

Update - Pogo Pin Alignment

We took some side by side pictures of the rear side of the Pi Zero with Pi Zero W and these align pretty close to the extent that we may expect the Hubpixed to still work.
