I see people selling 8-port capes, as if maybe this is a simple one device per bus routine... Wouldn't help me! As for the considerations of long buses, yes there was a learning curve. I have both active pull-up and active pull-down, with careful source-end termination. All cable is CAT-5, and all sensors are within 1m of a single linear topology installation. In several cases the bus goes out one pair of the CAT-5 to a distant sensor and comes back on another pair of the same cable to continue to the next destination. Branching.in a star fashion is death to 1-Wire. My current system works, reliably controlling serious solar hot water and outdoor wood boiler operation that could blow off expensive antifreeze fluid (a huge hassle to recharge) if anything overheated.

[beagleboard] Re: Angstrom Abandoned for BBB? Rumor + a Rant
I just want to add to this thread, that although Terry stirred a bit, but information that followed has been very informative. I'm new to BBB and have lots of experience writing Linux x86 type drivers for ISA, PCI etc. But I'm having a hard time figuring out what my main starting point of development should be. I need to able to build the different parts from scratch. And hopefully contributing when I do understand how everything piece together. But what I had a hard time with was where Yocto is layered, Angstrom or even the TI-SDK. And what my best point of focus is. One actually invest huge amount of time trying to get each repo going and some times get stuck because of a fault in a meta layer. Sometimes trying to fix some of the scripts, but I'm trying to avoid spending time on somethings that is not mainstream or actively maintained. But by everyone that replied it help bit by bit to understand these different parts.

Does your cape work? My LCD3 Rev A2 cape works on Beaglebone Black (didn't try on white). My audio cape Rev A works (recognized, didn't try to play or record audio) on both Beaglebone black and white but I noticed that HDMI audio disappears from proc/asound/cards when this cape is mounted. This might be normal. DVI-D with Audio cape doesn't work on either Beaglebone black or white. To be honest I'm not exactly sure if the cape works as I have got it second hand and never tried it before.

We are shipping boards as you can see form the daily updates on the support Wiki. They go to the distributors. They fill their back orders. No stock shows up because they are going to fill the back orders. When the distributors have extra boards, they will then show up as having inventory.

Still I insist no to use a laptop but remain standalone with my hardware. Copperlan is for win7 /XP and OSX - they´re working on changing that, still there´s some light (in which you come in), telling: (Copperlan QA: Which computing platforms are supported? (MAC, PC, Linux, others)): Since day one, CopperLan was planned to follow the evolution of the market. It currently runs on all 32/64 bit versions of Windows XP, Vista, Seven and MAC-OS X (Mac Intel). We are convinced of the relevance of porting CopperLan to Linux and plans are in place to support it in the future. Right now, it is available for Embedded Linux on ARM based processors. We have applications for Apple's iOS, and we plan to follow other developments as they unfold. Could you tell me, is the BeagleBone Black the right choice?

[beagleboard] Re: BBB Bare Metal with HDMI
Thanks for the info. I downloaded the driver code you referenced and it looks workable, but very incomplete. So next I downloaded the datasheet for the TDA9983. That's more along the lines of what I was expecting in the datasheet for the 19988. How close are the registers for the 9983 to the 19988? Are they a spot-on match? I know the rest of the information will be different, but the registers are all I care about at this point. I can figure the rest out once I have that part down.

I was working on implementing EDID reading (i.e. getting the supported resolutions, etc from the connected display/monitor via the HDMI chip). I searched far and wide and there isn't documentation with register definitions for the TDA19988. I sort of had to piece things together using the datasheet for a similar chip (TDA9983B), that pre-production draft of the TDA19988 datasheet (I think it's the one you are referring to), some example code from NXP (Google search for LPC4350_FPU_TFT_HDMI-v2.0.zip), and the Linux driver sources. I've contacted the author of the Linux driver and various people at BeagleBoard.org and that's the only documentation available. Well, there is the Minix driver now but it only does EDID reading at the moment (no hdmi output as there isn't a driver for the am335x lcd controller yet for Minix). As for initializing the chip. Yes, there are several commands you need to send it via I2C to turn on the HDMI interface and configure the output. Thomas On Saturday, January 18, 2014 3:26:27 PM UTC-5, Travis Estep wrote: Hello! I've been hacking around with the BBB for some time now, mostly doing bare metal programming. On other boards that I build projects with, I usually use one of my TFTs that I have laying around and use my custom graphical interface for the UI part. But the BBB is different. While I have been able to use a TFT with it, I'd like to get the HDMI up and running on bare metal if possible. Looking over the datasheet for the TDA19988BHN I can see that basically it just takes the LCD RGB signals and concerts that to HDMI output. However, I have not had any luck with feeding it from the library I wrote for my TFT. Is there something different I need to do with the signals? Does the HDMI chip require some kind of initialization before being used? The datasheet I have is one that I found on some third party website and I suspect it may be incomplete. I can't find the official datasheet on NXP's website at all. Any help would be appreciated. Any advice for anyone else who has had success in this arena would also be much appreciated.

I am getting this same issue on my new BBB running ubuntu saucy 13.10.

Hi Dave, [Note that I might be biased, being the designer of the BeBoPr boards] Here are some facts: The BeBoPr+ is no longer being made, it will be replaced by the BeBoPr++. The BeBoPr++ will be the low-cost replacement for the BeBoPr+ and BeBoPr plus Bridge combination. Right now I'm making an initial batch of 100+ boards. These should be ready for shipping in the second half of February. Have a look at the support forum (http://forum.bebopr.info/viewforum.php?f=4) for more information and links to the wiki pages. Since you're asking for differences, the most obvious difference is that the BeBoPr has no on-board stepper drivers chips. One can use the BeBoPr with either low-cost Pololu compatible stepper modules or use off-board heavy-duty motor drivers. The BeBoPr boards have been available for over a year, since the original BeagleBone (white). It was the first cape to support LinuxCNC and the BeagleBone.

Re: [beagleboard] BBB VS Radiation?
There is no such thing as an official industrial version. If you were to replace all the parts with industrial parts and pay the extra money, then conceivably you can have one.

Re: [beagleboard] Copperlan -installing
ok, so what exactly IS CopperLan and how does one interface to it? What is the protocol stack implimented? does the beaglebone have the right interfaces to use it or do you need to follow some custom electrical spec at the hardware level to interoperate with it. does the beaglebone have these things? does copperlan run on one or all of these distros common on beaglebone: angstrom, debian, or ubuntu? how is copperlan installed? These are ALL questions you need to ask the makers of copperLan before formulating and asking more specific questions here.

Re: [beagleboard] BeBoPr+ vs Replicape
I am actually trying to use your LinuxCNC MachineKit on a steel router/printer/digitizer with a 4'x8'x18 build area that I am building (see here http://whereismyflyingcar.info/?cat=3). I am making good progress and will be mounting motors and wanting to see them move in the not-too-distant future. I plan to use a bipolar NEMA 34 (4.6Nm) dual shaft motor with a 5.5A-6.5A per phase draw for the X axis and I need to make sure I get a stepper/driver board that will handle that sort of load. I suppose that since the BePoPr++ allows for off-board stepper/drivers I need to go with that one as I doubt the built-in devices on the Replicape can supply that sort of power. Right now I am playing around with a 0.23Nm stepper motor and an EasyDriver board hooked up to my BBB. Which makes me wonder... what if I just hooked up 6A versions of the EasyDriver to my BBB to drive the motors and ran LinuxCNC? I am moving motors without a BeBoPr++ now, why do I need one? what does the BePoPr++ do exactly?

[beagleboard] Re: Windows 7 doesn't mount BBB as usb drive after update
Hi, First, I will like to say that I am new to this, but I had the similar issue with NO USB SOUND AND NO MOUNT after update the Angstrom to the last version (2013.09.04 version). After first two trials to update (both by using the uSD flasher image) I got the same issue like you describe. I searched the NET (and found this post and others), but no one seems to have a solution...so I tried again, this time without much hope... So I did flashed the emmc again (using 5V 3A power supply on the 5.5/2.1 connector and NO other cables like network, usb, etc connected), then when the 4 leds lights up and remain so for like 30 seconds (in my case took about 52 minutes to flash...more than specified in most forums, not sure why...) I took the power off, then removed the uSD card. The next thing I done was to start the board by using ONLY the usb cable (I have another one, not the one that comes with the board, but that one works to) and connected the board to the USB of my Win 7 x64 PC via a USB external powered HUB with 2.5A power supply. At this moment, the board started (also started last times, but not detected by the PC as USB device) and after the LEDs lights up in some patterns for about10 seconds, then my PC detected the BBB board as USB device (usb detection sound, driver installation, etc) and all went fine. Now the board works just like before update: I can access it with SSH by using only USB connection (no network cable), I can access http://192.168.7.2, and so on. Next thing I want to have done is to use an RTL 8188cus based Edimax ew-7811un WLAN stick to get WiFi connection (this is why I needed to re-flash the BBB since I killed the other Angstrom by trying to have this working, so the board did not boot anymore after a lot of install, compile, and so on). It may be that your problem is different, but for me looked the same, so I posted my experience here. Hope this will solve your problem! Have fun!

[beagleboard] Re: Reading a Quadrature Encoder connected to a Beaglebone [black]
Hi, yesterday I was finally able to get it working! I think that agni... is having the same error: when executing the echo of eqep in slots I get the same invalid argument error. I get the additional details executing a dmesg command. Investigating on device tree, I found that form some reason the installation script didn't installed the DTB files on the SD. From what I understood: 1. the patch should add the EQEP tree items in linux-dev/KERNEL/arch/arm/boot/dts/am33xx.dtsi (you can verify searching for eqep in it) 2. The ./tools/rebuild.sh should build the DTB files and create an updated tar.gz file in linux-dev/deploy with the new version of the device tree 3. Then the ./tools/install_kernel.sh should install the kernel and copy the new DTB to the correct destination folder Suspecting to have outdated DTB, I deleted the linux-dev/KERNEL/arch/arm/boot/dts/am335x-*.dtb and re-executed the point 2. This re-created the DTB files. Then I manually copied them to the SD, in the /boot partition (and a subfolder that I don't remember in this moment, but you can find easily since it contains the same files). This fixed my issue!!! Sincerly I suspect that my version of ./tools/install_kernel.sh is newer than the one shown in http://www.youtube.com/watch?v=HJ9nUqYMjqs . But I don't know if this is a real bug or it is caused by my configuration. To get the encoder to work I also had to disable HDMI and HDMIN, as explained in https://groups.google.com/forum/#!topic/beagleboard/aU__9RGq3xU Hope this helps.

[beagleboard] Re: bitcoin mining on BBB
Even if electricity is free, mining on the bbb will return next to 0 returns. I have a mining setup for 2gh/s and I'm getting 0.0006 btc a day, that's basically 0.50$ a day. It's not worth the effort and the hardware, but I keep doing it because it's already set up and running w/o intervention. With 1 bbb you're looking at a hundred times less (note: total guess... I think my main PC did 300mh/s CPU so it's probably even worse than -100x) than what I make. Maybe lite coin might be better because CPU mining is still viable on that I hear. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

What packages am I likely to need for routing on the BBB? for printing? Can LinuxCNC do routing and printing? Both boards mention something about some software/firmware that comes on/with them... what is that about? For both routing and printing, you need some form of motion control software. Both tasks are very similar (coordinated moves in multi-axis space), but each has it's own unique requirements as well (spindle speed and coolant for routing/machining, extruder and heater control for 3D printing). AFAIK, there are currently three solutions for natively controlling a CNC machine on the BeagleBone: * The software written by Elias to run the Replicape * The software written by Bas to run the BeBoPr * LinuxCNC, which is a generic machine control platform traditionally used on x86 machines * Let me know if I missed any! All three available solutions use the on-board PRUs (dual 200 MHz 32-bit deterministic micro-controllers a.k.a. Programmable Realtime Unit) to generate step/dir signals with precision timing that is unaffected by the generally lousy interrupt latency performance of the ARM core. LinuxCNC uses a real-time Xenomai kernel and provides a programmable HAL (hardware abstraction layer) you can use to wire up various operating blocks to control your machine (things like PID controller loops, filters, gain and multiplexing stages, etc). I believe the software from both Bas and Elias run on a regular kernel, and rely on the PRU to do more than LinuxCNC (ie: things like motion planning and velocity/acceleration profiling), but I'm not 100% sure as I am not real familiar with either code base. One thing I like about LinuxCNC, is the ARM core to do the motion planning via Xenomai real-time threads, meaning the GHz CPU and FPU can be used for tasks like non-trivial kinematics. I first started looking into LinuxCNC because I wanted to control a linear delta printer like the Kossel, and I am actively working on adding kinematics for other non-Cartesian machines like the Wally and GUS Simpson. Brandon Heller is farther along than I am on the linear delta front, and has a nice video on G+ of printing using LinuxCNC on the BeagleBone: https://plus.google.com/104919785646757688261/posts/i7XvKHi2c39 -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] BeBoPr+ vs Replicape
No non-Cartesian stuff for me yet! Whew! I think I will be sticking with your MachineKit and doing my own cape (my business partner has done many PCBs more complicated than a stepper/driver cape) What does LinuxCNC use as its input file for a print or a route? I understand the concept of G-code as it applies to cutting with a router or laser in 2D, and I know G-code has control of the Z-axis as well to elevate the head for printing, but I don't understand where all the 'layered' G-code comes from when you want to print a 3D shape.

[beagleboard] Will we lose access to BBB pins when LCD cape is connected?
Hi, I am searching for an LCD cape for Beaglebone Black and came across this product: https://www.sparkfun.com/products/12085 From the images provided on that page, it seems we lose physical access to BBB GPIO pins once the two are connected together; LCD cape's male connector mates with all the pins on BBB. If true, how do we make connection with other peripherals in the system? For example, a microcontroller. Please suggest an LCD cape where this issue doesn't come up. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Have you considered the noise could be on the power lines which power the touch screen? One could assume the power rails are meant to be between GND and VCC, however this may not be the case. It then assumes GND is 0 and VCC is Max. Since there are 4 AIN's used, it should be possible to read the voltages... Maybe do some sort of ratio calculation or something. Just a thought.

Hi Dennis! it's a clone of BBB with some extra features. http://www.mentorel.com/product/usomiq-am335x/ 2014/1/20 Gerald Coley ger...@beagleboard.org There is no such thing as an official industrial version.
