[beagleboard] Re: GPIO Digital input voltage more than 3.3V
The Texas Instruments TBX0101 IC should do the trick. The BBB connects to port A and the speed sensor to Port B. Use the BBBs 3.3V supply to connect to VccA. Depending on the speed sensor supply I'd regulate that down to +5V to connect to the VccB pin (can only take up to 5.5V max). Farnell do the IC part number 2335605. There's a good data sheet to accompany it as well.

[beagleboard] Beagleboneblack: Display performance issue, while interfacing with MIPI
Hi all, Currently we are facing Display performance issue. i.e, display is not building up quickly. For Your Information, 1. We use Beagle Bone Black board and debian, By default *CONFIG_NEON is enabled* in kernel(3.8). 2. *[ Beagle Bone Black (LCD controller + SPI)] -- [MIPI (SSD2828)] LCD.* 3. We run *clock frequency as 68.43MHz*, Hope this should not be problem as Beagle Bone Black support upto ~120MHz. 4. Number of pixels - *1280 x 800.* 4. We use *MIPI bridge(SSD2828)*, to interface with MIPI LCD. Let us know if there is any steps that we need to take care to resolve this issues. If there is any way to figure out or test the display performance will be helpful to narrow down the issue. - Nobel -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Hi, What your are seeking for will work under every standard OS. The questions is not if it works, the question is which latencey you can accept - means how fast must thread A resume after the 10ms elapsed? To get an idea what BBB can do I reccomend to have a look at toyooka_LCJ2014_v10.pdf http://events.linuxfoundation.org/sites/events/files/slides/toyooka_LCJ2014_v10.pdf . I would not be surpised if Debian w/o any patches can fulfil your latency needs.

[beagleboard] Adafruit Library - Disable GPIO cleanup
Hey guys! Maybe somebody of you know the solution to my problem. I use the Adafruit_BBIO.GPIO library in my python programm. With that library I set or clear some GPIO. All that is no problem. But, if I leave my script, my previous setup of these GPIO is lost and all GPIOs have the value that's given through the pull-resistors of my PCB. I googled that and could read, that the GPIOs are set to floating if the script is leaving (clean up process). For my purpose that control isn't desired and should be disabled. Are my assumptions with the clean up process right? Is it possible to disable or walkaround this clean up at the end? If yes, how? :-) Thanks for your help Dave *P.S.

[beagleboard] programming BBB - choice of language
Hello All I'm starting to design a commercial project which will use a number of networked BBB's as process controllers. While Im an experienced DP guy, Im an absolute newbie with the BBB hardware and software. I'm at the point of choosing a language in which the applications will be written. The main application will be a no-user, stand-alone, repetitive data-processing application, so I want a language with the following characteristics : 1. high level 2. procedural 3. modular - high cohesion and low coupling 4. non-object oriented 5. strong array processing 6. runs under Linux 7. compilable My research tells me that Python is the most-used high-level language within the BBB community, but it fails ( at least somewhat ) on several of the above requirements. My research tells me that XBasic ( which satisfies all of the above ) doesn't seem to be much used within the BBB community. My Questions, therefore are : A - XBasic is said to run under Linux - does anyone know of a reason why it would not work on the BBB ? B - am I missing something profoundly wrong with XBasic which precludes its use ? thanks very much for taking your time to help me out richard -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

The steps for saving off your eMMC contents to a file:
* Get a 4GB or larger uSD card that is FAT formatted.
* Download https://s3.amazonaws.com/beagle/beagleboneblack-save-emmc.zip
and extract the contents onto your uSD card.
* Eject uSD card from your computer, insert into powered-off BeagleBone
Black and apply power to your board.
* You'll notice USR0 (the LED closest to the S1 button in the corner) will
(after about 20 seconds) start to blink steadily, rather than the
double-pulse heartbeat pattern that is typical when your BeagleBone Black
is running the typical Linux kernel configuration.
* It'll run for a bit under 10 minutes and then USR0 will stay ON steady.
That's your cue to remove power, remove the uSD card and put it back into
your computer.
* You should see a file called BeagleBoneBlack-eMMC-image-X.img, where
X is a set of random numbers. Save off this file to use for restoring
your image later.
Because the date won't be set on your board, you might want to adjust the
date on the file to remember when you made it. Delete the file if you want
to make room for a new backup image. For storage on your computer, these
images will typically compress very well, so use your favorite compression
tool.
To restore the file, make sure there is a valid
BeagleBoneBlack-eMMC-image-.img file on the uSD card and edit
autorun.sh with your favorite text editor to contain the following:

echo timer /sys/class/leds/beaglebone\:green\:usr0/trigger
dd if=/mnt/BeagleBoneBlack-eMMC-image-X.img of=/dev/mmcblk1 bs=10M

[beagleboard] Re: programming BBB - choice of language
It's a bit of an contradiction for me that you ask for modularity but don't want an object based language. Development of XBasic seems to have stopped about 2002. The community that could help you will be rather small. Much of the documentation is not available anymore. I can only assume that this is an interpreter language as most of the basic dialects (although sourceforge category is 'compiler'). This means you would need to compile the interpreter sourcecode for the ARM before you can use it. I would recommend a more recent language with a bigger community. I never needed any other language than C++. Here and than I thought I need to learn java, but than I never needed it. C++ is probably the best supported language on Linux systems. If you don't want objects you don't need to use them.

Re: [beagleboard] Re: programming BBB - choice of language
It's probably time for you to embrace modern technology, and forgo some ( or all ) the restrictions you're placing on yourself. Past that. these restrictions are not reasonable. A programing language is a tool, and every took has its intended use, C for example could possibly work very well for your situation, but really depends how important the above restrictions are, restriction #1 would have to go, and restrictions 3 5 may fit the bill, depending on your definitions on each. C is very modular in the context that you can compartmentalize your code, and strong array processing . . . would depend on you, your ability to find a good library, and / or using regular expression. Another consideration would be what exactly are you building ? Some languages are better suited for different types of projects. Not necessarily the languages in of themselves, but the libraries, or quality of libraries available to the given languages. No one in their right mind would deny that you *could* write a web UI backend using C, or even ASM. But something like Nodejs ( javascript ) may very well make more sense in the long run.

Re: [beagleboard] Re: programming BBB - choice of language
hi William thanks very much for replying you are absolutely right that a programming language is a tool, and a metaphor that resonates with me since Im also a woodworker. I know that I can use a jackknife or an axe to shape a board, but a saw and plane do the job better and with less work, so I always use the tool that is appropriate. You've clearly spotted the fact that i'm an old-timer, but i'll take an old-timer's perogative to give you my point of view - the 'restrictions' you think I should forgo are not restrictions I place on myself, but the design considerations required by a mindset that goes back to the old days when it was unthinkable to release a piece of code with even one error in it. By consciously selecting the tools that will produce the best job, I actually free myself ( and the coders i hire ) from endless recoding and patching. however, enough of my rant :-) you're also right to ask what Im building and relating it to the language I use - since the product will NOT be an end user product, it doesn't need slick web dodads or gui interfaces. what the product will be is process control code applying a patented logic through a network of microprocessors which control an industrial process through hundreds of sensors and relays. what it needs is perfect code, easily written and easily maintained that will run 24/7 unattended without fail. That is why my list of requirements is what it is. The only thing 'new' in what i'm doing is the BeagleBone black microprocessors which weren't available in the 'old days'. Sadly, the modern software technology ( and i daresay the modern software coders' mindset ) is responsible for the shoddy and error-ridden code i see almost everywhere. I'm hoping to avoid that trap. Your tip about good libraries is also a very good one, and one that I am actively pursuing ( but of course, I need to choose a language in order to use the library, don't I :-) ) not sure what you mean by 'regular expression' anyway, I really appreciate your taking the time to offer your advice, and I hope my ranting hasn't been discourteous. regards richard On 3/9/2015 4:44 PM, William Hermans wrote: It's probably time for you to embrace modern technology, and forgo some ( or all ) the restrictions you're placing on yourself.

Re: [beagleboard] DTO and GPIO output error
A possible and likely cause of this problem is that you are compiling for dynamic linking with the c libraries at run time, and the version of the c library you compiled against, and the c library you are trying to link against at run time, are different and non-compatible. This is a possible problem when cross-compiling. What version of glibc.so are you compiling with? (The one in your cross-compiler host.) What version of glibc.so are you trying to dynamically link with at run time? (The one in your BBB.) Either you need to get the libraries to match, or at least be compatible, or include the compiler libraries as hard linked inside the executable. This will cause your executable to swell up in size, but will guarantee that the c libraries match. --- Graham == On Monday, March 9, 2015 at 8:09:04 PM UTC-5, Karl Anderson wrote: Here is a link to the readme, which details how to download the repo and execute it: https://github.com/BestFriendofDoug/PRUSS-C For some reason, the prudebug is not recognizing the executable, even after I downloaded and untar-ed the file see error below: root@beaglebone:~/prudebug-0.25# ls -l total 184 -rw-r--r-- 1 debian debian 8698 Mar 8 2014 cmd.c -rw-r--r-- 1 root debian 1591 Mar 8 2014 cmdinput.c -rw-r--r-- 1 root root2264 Mar 8 2014 cmdinput.o -rw-r--r-- 1 debian debian 10512 Mar 8 2014 cmd.o -rw-r--r-- 1 debian debian 7302 Mar 8 2014 da.c -rw-r--r-- 1 root root8120 Mar 8 2014 da.o -rw-r--r-- 1 debian debian 1510 Mar 8 2014 LICENSE -rw-r--r-- 1 debian debian 136 Mar 8 2014 Makefile -rw-r--r-- 1 debian debian 6176 Mar 8 2014 printhelp.c -rw-r--r-- 1 debian debian 8484 Mar 8 2014 printhelp.o -rw-r--r-- 1 debian debian 16769 Mar 8 2014 prudbg.c -rw-r--r-- 1 debian debian 2607 Mar 8 2014 prudbg.h -rw-r--r-- 1 root root 13240 Mar 8 2014 prudbg.o -rwxr-xr-x 1 root root 41276 Mar 8 2014 prudebug -rw-r--r-- 1 debian debian 9495 Mar 8 2014 README -rw-r--r-- 1 debian debian 1238 Mar 8 2014 uio.c -rw-r--r-- 1 debian debian 549 Mar 8 2014 uio.h -rw-r--r-- 1 root root2016 Mar 8 2014 uio.o root@beaglebone:~/prudebug-0.25# sudo ./prudebug sudo: unable to execute ./prudebug: No such file or directory On Friday, March 6, 2015 at 4:19:23 PM UTC-6, Jason Kridner wrote: That URL doesn't point to the source code.

Re: [beagleboard] Re: programming BBB - choice of language
Richard, I can not state it any better than wikipedia ( regular expression ). http://en.wikipedia.org/wiki/Regular_expression Basically like wildcards, but much more powerful. Now as to whether or not just using regex represents strong array handling . . . again that depends on your definition. When I mentioned a web UI backend above that was just an example, but what you're describing seems to fit C very closely, No, C is not high level, but as long as C has been around, you can almost guarantee you'll be able to find a library that will work for you. An executable compiled from C can also be very compact, and super fast. Now for sure, an inexperienced developer can write bad code in C, however this is true of any language. Possibly more so with C, since it is a very powerful language. A language that also demands you understand what your code does. But again . . . this is true for all programing languages out there. Easy to maintain ? Bug free code ? This is all the responsibility of the developer(s) using any language. I would also consider how much bloat many of these high level languages add to an executable when compiled. With all the above said, one other language did come to mind after thinking about it a bit. FreeBasic, but I've never used it. So I have no idea what the BCL ( base class library ) is like, and no idea how many libraries exist for it. It is one of the few languages I hear of now and again, but have never looked in to. Mostly because I try to distance myself from any form of basic when possible. Funny that back in the early 90's the first languages I started with was quickbasic . . .

Re: [beagleboard] Re: programming BBB - choice of language
I might also mention Perl, except that it is not exactly a compilable language. Compilers do exist, but may not exist for armhf yet. Perl is very well known for its string manipulation as well as it's very ugly syntax . . .

Re: [beagleboard] Re: Can't get BBB to boot
Hi, I don't know if you follow anymore or if you already gave up. I just wanted to point out that since March 2nd new images are available. I overlooked it myself until yesterday. The one for eMMC is not directly on the latest image http://beagleboard.org/latest-images site, but here http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBB_Rev_C_.284GB_eMMC.29 (for BBB Rev C). Boot switch seems to work like expected. You can leave the SDCard in the slot after reboot.

[beagleboard] My beaglebone is Corrupt
good morning, community, I am new with the Beaglebone Black rev C, the board started to be slow or blocked even using a terminal (shell), after that I try to reboot but it appear on the screen of my monitor just 15 or more lines about that it does not recognize ports, GPIO, Hdmi, and not boot, or not enter to the debian distro. The led 0 (USR0) remain blinking with the led 2 (USR2) while the screen seems to be paralized on those errors. On the web there is not reference. another thing, I try to recovery of my data and codes that I did on the Emmc, but the procedure does not work, not read the uSD, and when I push the S2 (chage boot), the leds do not Blink. ??? Someone knows what happen with the Board, or How I can save the data first, and how I get it back.??? In this moment, I can not do anything with the board.
