How to develop a Linux binary for the BeagleBone (any colour) on Windows in CCS, using BB guru Derek Molloy's GPIO lib. This blog has a history. I was working with my very good friend martinvalencia to get this working. This blog shows the end result: how we got it working. Not shown: all our failures when discussing this over Hangouts.   Derek Molloy is arguably the best source for BB tutorials. His libraries are well designed too. Here's an instruciblo on how to use his GPIO lib wit ...
Debugging your PRU C code Recently I decided to turn my attention to the fairly unique Programmable Realtime Units on the BeagleBone's TI Sitara processor. My earlier blog post covered Coding for the BeagleBone PRU with C in 2019 and hopefully showed how it's become easier to work with the PRUs over the last few years. Whilst it's great to be able to write C code in a nice IDE before deploying, it's even better if you can debug your code and see what's happening when things don't quite go to pla ...
How to develop a Linux binary for the BeagleBone (any colour) on Windows in CCS, auto-deploy it to the BB and remotely debug. No hardware debugger needed - all runs over TCP/IP The great PRU blog from Fred27 inspired me to pick up the BeagleBone Green again. Because he uses CCS as development environment, it makes sense to also use CCS for Linux native C and C++ development.   I've blogged before on  how to set up a BeagleBone C/C++ environment with the ARM DS-5 suite. Both DS-5 ...
So, I've recently decided to get my head around the killer feature of the BeagleBone family - the two Programmable Realtime Units that sit alongside the ARM Cortex A8 core that you'll normally find running Linux. These PRUs are what really set the BeagleBone apart from other SBCs like the Raspberry Pi. To be honest, if you just need to run Linux on something small then the Pi may be a better choice - quad core 1.2Ghz A53 vs the BB's single core 1GHz A8. For anything that requires accurate and pr ...
I have a project going (home brew pinball machine) that is already using NeoPixels driven by a Beagle Bone Black via the Beagle’s PRU.  I needed to add 7 segment score displays, 26 digits worth!  I ended up with the solution that follows, thought you all might be interested.    I designed a custom PCB using WS2811 chips that makes the displays work just like Neopixels.  Now I can drive the displays and other WS2811 parts / Neopixels all in the same serial stri ...
Here is short presentation of initial test of DLP LightCrafter 2000 EVM connected to BeagleBone Black Wireless board. I would like to use this board to create portable theater projector for watching movies e.g. from Youtube or Netflix.   ...
Test Driving the BeagleBone Blue RTV The BeagleBone Blue Road Test Vehicle. This test vehicle is powered by the BeagleBone Blue and was constructed from lightweight and cost effective recycled materials. The BeagleBone Blue is ready to go. https://beagleboard.org/blue   Available at http://www.newark.com/beagleboard/bbone-blue/beaglebone-blue-robotics-platform/dp/95Y0640?st=beaglebone%20blue   What is BeagleBone Blue?   BeagleBone Blue is a complete, Linux-enabled robotics ...
BeagleBone Blue - Drive Motor and Steering Servo Tests   The BeagleBone Blue is ready to go. https://beagleboard.org/blue   Available at http://www.newark.com/beagleboard/bbone-blue/beaglebone-blue-robotics-platform/dp/95Y0640?st=beaglebone%20blue Front View of the BB Blue RTV (Road Test Vehicle) Side View Rear View Top View. Bottom View. The motor is powered directly from the BB Blue via 2-Pin JST-ZH Connector. The cable for the steering servo is also conn ...
Here I am testing the operation of micro servos with the BB Blue under  the power of a 1600mah Lipo battery.   ...
Beaglebone Blue Road Test Vehicle   Hello Beaglebone fans! Thanks for stopping by this post.   I am currently test driving the Beaglebone Blue for the Element 14 Beaglebone Blue Robotics Controller Road Test. What better way to test the BB Blue then to build a test vehicle.   This test vehicle is constructed from recycled materials. It is still under construction. Here are some photos of the progress.   The steering servo has not been installed and the motor is not ...
    This is a simple test of the Beaglebone Blue Robotics Controller with a Pan/Tilt Camera Mount. The micro servos that came with the Pan/Tilt are not that great for precision control but will suffice for the purpose of this test. These servos will likely be replaced with higher grade servos at a later time.   I would also like to mention, the BB Blue is being powered by a 12V 2.5A Power Supply. The BB Blue is meant to be powered by a Li-Ion Battery. The battery should arrive ...
This blog post discuss a weird  issue I faced when upgrading (apt-get upgrade) the Beaglebone blue and how I overcame the issue, basically the lesson learnt here is to enable SSH on the Beaglebone before doing anything else.   In addition, in the second half of the blog, I have also include the list of commands I used to setup USB webcam, to steam video over WiFi.This is going to help with demoing the features of the Beaglebone Blue as part of my Roadtest review, and a  couple mi ...
Pro Perspective: Unleashing BeagleBone Blue This webinar will be presented by Jason Kridner, co-founder and board member at BeagleBoard.org Foundation and Open Platform Evangelist with Texas Instruments. Seating is limited, register now!   Tuesday, July 25, 2017 7:00:00 PM BST - 8:00:00 PM BST Tuesday, July 25, 2017 2:00:00 PM EDT - 3:00:00 PM EDT   Welcome back to the BeagleBone Blue series! There’s nothing more satisfying than seeing your robotics project come to life, and ...
BeagleBone Black Wireless in an Altoids Mint Tin   Curiously Stong Mints? No, but it is quite powerful. It's a BeagleBone Black Wireless!!! The Adafruit Proto Cape Kit fits with lid fully closed. In order to accommodate additional components such as sensors, wiring, and others things, it will be necessary to find some Nylon Polyamide Standoffs that are shorter than the 3/16" standoffs used in the photos. These are the standoffs that came with the Adafruit BeagleBone Proto Plate ...
Since Beaglebone Black(BBB) internal memory is limited to 4GB and further more, 3.5 GB is already allocated to system and other process. Hence for us to install new modules/programs very less space is left. So it is good idea to use 8/16 GB SD card instead. We can boot from SD card and use the left over space in card to install other modules and programs.   To enable this feature, we must format, partition, resize the SD card. Please follow below steps to achieve this: 1) Format the 8 GB ca ...
