Raspberry π 2 Ships Half Million In First Two Weeks

The next-generation Raspberry π seems to be doing rather well right out of the starting gate <http://www.theinquirer.net/inquirer/news/2395948/raspberry-pi-2-sales-top-500-000-in-two-weeks>. Meantime, while total sales of both old- and new-generation π models have wildly exceeded expectations, there is some dispute over the Foundation’s claim that it has become the best-selling British PC maker ever <http://www.theregister.co.uk/2015/02/18/raspberry_pi_5_million_sold/>.

Anybody already ordered one and gave it a spin? Could be a nice hands-on demo for one of the upcoming meetings... Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

I was going to order one but element14 were out of stock, and I didn't bother to put through the order. I do intend to get one. I probably could demo one (and the beaglebone black if people like) at a future meeting but will have to rearrange my other Monday commitments to do so. Cheers Michael.

That'll be great! Let us know when you'll be able to do a demo of Pi2 and beaglebone. Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

I have a PI 2 on my desk, just waiting on a case for it if people want a look at some point On Thu, Feb 19, 2015 at 10:41 AM, Peter Reutemann <fracpete(a)waikato.ac.nz> wrote:

How about this agenda for the March 23 meeting? Andrew - Pi2 demo Michael - BeagleBone demo Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Can do. How longer demo would people like, and anything people would like to see? Also, does the uni have HDMI so it can put its video up onto screen or will I need to make some kind to adapt to VGA? On Thu, Feb 19, 2015 at 10:55 AM, Peter Reutemann <fracpete(a)waikato.ac.nz> wrote:

I leave that up to the other members. ;-)

The projector itself has HDMI, if I remember correctly. Ian Stewart would know. VGA only is available if from the desk at the front. Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

I believe the Uni is working on getting all lecture theatres updated to HDMI, but one of the teaching technology guys tells me that progress is slow because it has often proved difficult to take a lecture theatre off-line long enough to update the computer and media gear. I suspect the smaller tutorial rooms in the Faculties are also right down the bottom of the list for upgrading so I would bet on it still being VGA. Cheers Michael.

Hi Andrew,

I have a 2meter HDMI cable that I bring along to each meeting. We have found that it is sufficient in length to do a demo if you do the presentation from the desk just underneath the video projector. The video projector has an HMDI input socket, and a maximum resolution of 1024 x 768 pixels. At the main presenters desk in the classroom the cable feed is from a SVGA male connector to the SVGA input on the video projector which is OK for laptops doing slide shows, etc.
How longer demo would people like If there is also the demo of BeagleBone, then up to an hour for each presentation is fine with me.

I have been trying to interface an IMU (inertial measurement unit) to the beaglebone black with the hope of getting a flight controller for multirotor drone running on it. It's currently pretty low-level stuff includying writing kernel code, cross-compiling kernels, and trying to understand and use from user space the IIO (industrial instrument I/O) interface of the kernel. Are people interested in that kind of stuff? Or would people rather a more general spiel on this is what the beaglebone is capable of and here go some applications and how to get started on it? Cheers Michael.

Michael, With regard to a presentation I think most people would be interested in both a general product overview and also your project to get a multi-rotor drone working. Here is my two cents as a general guideline for presenting... History Overview: Date of products first manufacture. Designers and Company that produce the product. Popular uses of the product. Models available, etc. Hardware Overview: CPU type, CPU speed, memory size, i/o ports, TOY clock, eePROM, power requirements, storage. etc. Software Overview: What's involved with Installing Linux and applications. Which distro's to use. Booting process. Pet Project: Show and Tell of some pet project you are getting the product to do. Doesn't matter if only some bits work or its not stable, etc., its what you are aiming to achieve that we are interested in. Questions: Questions and Answers session. cheers, Ian. PS: NOTE ON INTERNET ACCESS. We no longer have any wired lan (RJ45 to RJ45) access to the internet. If your product has wifi then we can supply access to the Uni's Lightwire wifi service. If you are presenting from a laptop (with wifi) and want to go on-line to a web-site to display information, then we will log you into the Lightwire network. If your product only has a RJ45 ethernet port and you need to connect to the internet, then we will have to create some magic for the occasion.

Programming always interests me, particularly the mechanisms in Linux to do low-level stuff from userland, _without_ having to resort to kernel programming. Is there a libiio, analogous to libusb, for this purpose?

Unforunately there does not appear to be. The IIO subsystem seems to be poorly documented, at least for user side access, and particularly poorly documented for use of triggers to get repeated measurements. Access is via sysfs (for configuring and one-time reads) and via dev nodes for triggered measurements into a buffer. I have the basics going but am really struggling to get triggered I/O going. I suspect I have to make a device tree blob entry for the boot process so that the kernel makes a link from a timer to the IIO trigger ... I am finding I have to get deeper and deeper into this with very little guidance/instruction on the web about it and ending up having to read kernel source code to work out how the hell to drive it. I was hoping to get first hand advice at LCA2015 from developers but unfortunately I had to abandon LCA2015 after the first day due to a death in the family. But I suspect if I can sort it out and write up something --- or even end up writing up a libiio --- that would be very beneficial to the community. Cheers Michael
