Beaglebone Black
Locked
 
|
For those wondering if the Raspberry Pi is right for them, consider
this: The Beaglebone Black.
It's less than USD50.
And if reading the rather dry spec sheets doesn't grab you, watch this short demonstration. Why not jump in? _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

It might actually be cheaper than the Raspberry if you count the power supply that seems to be included.
Also, 2GB memory is not bad at all. I saw a Java for ARM/Beaglebone on Oracle's site if I am not mistaken. I think it shows competition is good and healthy, so we get nice and useful toys. I mean processors. Even the Raspi has more cycles than the 4381 I started on. René. On 24 apr. 2013, at 18:31, Tom Maynard <[hidden email]> wrote:

I can't help but step out of the shadows and lurk no more. As a manager
of an IT department at a public library, I found that Via Technologies' APC bears looking into as well (http://apc.io). I configured their introductory model 8750 (about $50) as a kiosk for patrons to access our online catalog, and it's been working out great. I installed Mike Thompson's Raspbian Apricot on a micro SD card and having it boot from that, although it comes with Android 4 pre-installed. Coincidentally, just today I configured a Raspberry Pi to do likewise (their model B), and the performance isn't nearly as good as the APC's. We have the high end APC Rock on order (about $80), and I can't wait to get my hands on it. Aside from 4GB of memory and an included power supply, another plus is that they also have VGA outputs. pax.

Made more so by your ability to compare the performance of these two units side-by-side, even if it's not a NetRexx application (or is it?). Any other suggestions forthcoming from the shadows?

My two cents worth: RasPi pluses: 1. -Composite video (RCA) output. Allows using the RasPi for "small display" usage scenarios just by hooking it to a dirt-cheap 2.5" / 3" LCD display that does NTSC composite video,and configuring video display at 640x480.

John,
thanks for this pointer, very interesting. NetRexx on Android is still a bit of an art, and I wonder if the availability of these machines will change that - it has the potential, I think. I only use the Raspi's with plain Rasbian Wheezy Linux, can't really complain about the performance ( but only did character mode stuff with it, am looking into running JavaFX with NetRexx shortly). I am looking forward to any reports on running NetRexx on the APC offerings. best regards, René.

Fernando,
I would be seriously hampered by the MK802 not having the set of GPIO expansion pins that the Raspi has. I never had so much fun with electronics as I am having with these little machines - light, temperature, proximity sensors, GPS, switching mains on and off, and all programmable in NetRexx. René.

Could you be convinced to post some of your code, René? Possibly on the NetRexx Wiki? I can't help but feel that this is a very possible direction for the spread/growth of NetRexx. Have you written your own library already? This might also become a community effort. I had reasonable hopes for the Parallax Javelin Stamp, but alas that has been retired and now few traces remain (and I adopted the Propeller ... but no Java [and thus no NetRexx] there). _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

It's one of my presentations at the symposium; I will certainly publish everything that is worthwhile.

I am not sure about the teleconferencing - if it works it is a bonus. "Details will be published when available."
Code and such would be great content for the wiki- something I unfortunately still did not find the time for to wrap up the loose ends of, unlike the forum, which fortunately is there now. I'll post some stuff to the forum, in the NetRexx part of it that is not reflected to the list. Still very much experimenting though. On the other hand, I am trying not to squelch any interest there might be in my presentations (which, following the old tradition, will come into being on some airplane above the caribbean sea). First I am going to launch a proposal about how to do 'address cmd' in NetRexx, which will give something away about my current favorite approach - as I indicated in my Dr Dobbs article, I think time spent in developing libraries is lost for developing interesting apps. As hardware design is done by integration of components, so should software - I read the Brad Cox book decades ago. At this moment one of our cats is playing with switching a lamp on and off by stepping into (and out of) the range of an infrared sensor that drives a solid state relay, through NetRexx code on a Raspi connected to a breadboard, with an LDR checking if the lamp actually emits light when switched on. If I had to design the SSR, or the AD converter (MCP3008) that I just stuck in the breadboard next to each other, it would not have worked yet and probably never been done - the same goes for the library - I found two that can do GPIO and SPI, but I found I'd rather use existing components available on the Raspi, originally written in C and Python - the application is rather tied to this one machine anyway - the tasks are simple. I still might recast the native C-library for Python that does SPI into JNI, but only if it is a quick edit. I'd rather find a good pure Java library for that. Anyway, there I am, telling too much about my presentation. Now for the mqtt client library I use, it is a different story - mqtt is an 'on the wire' protocol and the eclipse-paho Java client for it makes that I can make mqtt do exactly what I want using NetRexx - and this is useful because the same component (JavaBean) runs unchanged on MacOSX and Linux on the Amazon VM image of which I haven't the foggiest idea which instruction set architecture it runs. best regards, René.

If going via a USB-attached peripheral board, why would one not just drive that from a PC or laptop/netbook/tablet/phone? Surely the 'point' of boards such as mbed, beaglebone, and RasPi, is to get people to use and understand the lower-level interfaces such as GPIO, I2C, UART, etc. I prefer 'barebones', myself: http://speleotrove.com/tollos/ Mike _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

Mike, The USB boards I've seen with GPIO include drivers/rs232 api so you do NOT need to do any USB low level programming AT ALL. Again, when RasPi can be shipped to my doorstep in South America for the same price as a MK802, I'd consider the RasPi. Specially because I like its composite video output, which MK802 boards lack. Until then, the cheapest approach for embedded playing is a MK802... It uses a serial interface... http://numato.com/8-channel-usb-gpio-module Of course, things are different for people living in the UK and USA which have local RasPi distributors. In any case, the more choice, the better :) FC PS: I didn't invent this, I originally was introduced to the MK802 by this Russian page. IMHO he's got a point. http://romanrm.ru/en/a10/mk802-server#why-not-raspberry-pi _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

Thanks again, Tom Maynard, for your

Didn't even know, what a BeagleBone is, at all ... :-( Too far away from the Fathers and Mothers of the Invention, maybe ... ... and also working from my home-office alone .... *and* Rick, Chip, all: ... that's the reason why I so frequently have to *ask something* here and/or at RexxLA: I actually don't live in the US, I'm living in Vienna, Austria .... *And* I am *not* working, as Rony, *on a University*, with lots of students.... Thus, I'm am *sometimes* dependent to be able to ask simple questions. To Friends, only, of course! Any *enemy* of mine: Just say so, I shall *never* ask you again, for sure !

Rene, I am certainly interested in your source code for manipulating the gpio pins. Your proximity sensor and SSR sound a lot like the app I am planning: a thermometer in a pot of water and an SSR to turn the heater
on and off till exactly 170F is reached and hold it there. Did you publish any of your work? Where can I search for it? Ken K From: [hidden email] [mailto:[hidden email]]
On Behalf Of René Jansen It's one of my presentations at the symposium; I will certainly publish everything that is worthwhile. René. On 25 apr. 2013, at 23:15, Tom Maynard <[hidden email]> wrote:
