So after breaking a BeagleBone Black by putting 5v onto the breakout pin on the P8 side... we were supplied with a new one! (thanks!).   This meant that I could go back to coding for the scoring system. After working out the pinmux, from various confusing (inaccurate) sources and cross-referencing with the technical reference manual(s), for the mode and setting the pin for input,  I had something which, when the infra-red beam is broken, turns a green LED on. I've created a nice sprea ...
Howdy!  I'm a member of Chicago's hackerspace, Pumping Station: One (website), and we are competing in element14's BeagleBone Black Hackerspace Challenge. Who? We are a federally-recognized non-profit organization with over 200 members and turned 4 years old back in April.  I shot the above photo at our original space before we moved last year to our current space which is much bigger.  I always liked how our logo looked on the wall there... and my photo also catches the most e ...
This week I intended on blogging about working and programming for the PRU in assembly and working with the GPIO.   Until I bricked the Beaglebone Black we were given.   Usually when you brick a device you can get it back up. Typically, it is the instructions/firmware on the flash chip that have corrupted or it's the operating system you're running on the board.   However, when you're wiring up the breakout pins (P8 / P9) and you accidently cross-wire the 5 volt line through a ...
We were not sure whom had time to work on the challenge, the majority of the members have full time jobs and other obligations, so evenings on weekdays and some weekends are often the best bet.   Paul Brook (pbrook) decided to head the challenge project, directing three other interested members; myself (Christopher Stanton / Stanto), Jon Stockill (nav) and Angus (ajtag).   We really needed a way to control the arms of the foosball table, and it was decided between PBrook and Nav that ...
Some have think tanks or mind maps, we just threw around ideas until something stuck over the course of a few days/weeks. Of course for a while we were introducing members of the space to what the BeagleBone Black actually was:   "Well, what can it do?"      "It's like a RasPi, mixed with a PiFace/Arduino, but faster, and done properly" "Okay, but what shall we do with it?"      "I dunno."   After everyone that turned up regularly enough was ...

BBB - Getting ACE working

Posted by shabaz Top Member Jun 16, 2013
Introduction The Beaglebone Black PRU cores are great for high speed operations. The AM3359 chip on the BBB contains an ARM core and two PRU cores amongst other modules. They run as independent CPUs at 200MHz, freeing up the ARM core for continuing to run Linux applications. It is quite amazing to have three processors in a single chip that are fairly easy to use. This post is about a library called ACE that could be useful for any method we create to communicate to the PRU cores easily, hopeful ...
2 Hackspaces... 2 BeagleBone Blacks... 1 Winner!   We're pleased to announce a month long challenge that will pit two transatlantic hackspaces against each other to create a fantastic project using the awesome BeagleBone Black! Each hackspace has been given a BeagleBone Black and challenged to come up with the most awesome project and then submit their results on element14. We've picked the two closest hackspaces to our UK and US offices to compete and here's a little bit more about them.. ...
Introduction This was a quick, fun exercise, to build a complete thermal camera using the Beaglebone Black, a small LCD and a thermal array sensor. It was really more of a consolidation, combining some earlier experiements.   The setup The image here shows the entire assembly, capturing an image of my hand (taken from about 1 foot away. It was hard to take a photo at the same time!).   The final code is attached. The information on each sub-section is at these links: Thermal arra ...
Disclaimer1: Apologies for the length - These notes are a record of experiments on the BBB, so I was verbose while it was still fresh in my head. Disclaimer 2: I'm a beginner with ARM and NEON assembler, so some of the information here may be obvious to some, or slightly inaccurate - if so, sorry in advance, and do let me know of any corrections.   What is it? NEON is a set of functionality inside the BeagleBone Black's ARM core, which provides hardware acceleration for operations that ca ...
BoothStache is a version of BeagleStache by Jason Kridner optimized for an expo hall booth at a conference (like DESIGN West).  Instead of a LCD cape, BoothStache uses the BeagleBone Black's HDMI port to display the webcam feed on an HDTV.   An added twist is a big red USB button that the user presses to send a tweet of their stache photo (thanks to Python helper that bonnie555 wrote called BeagleButan).  Here's the setup: And here's a video:   The twitter accou ...
