Python – as the system shell | Nathaniel R. Lewis

Nathaniel R. Lewis. Python – as the system shell. July 24, 2013. I have absolutely no idea if this is useful for anyone (embedded systems? But I was creating a user on the new OS image i’m using for my Beagleboard xM and wondered what would happen if I specified python as the login shell for a user. So anyway, it worked, and you get the python shell when you log into the system. Using a Beaglebone with an HC-SR04 sonar. Beagleboard xM @ 1 GHz. Leave a Reply Cancel reply.

Nathaniel R. Lewis. Kybernetes at Robogames 2013. April 28, 2013. Kybernetes is a test platform for autonomous navigation I developed with the Robotics Society of UC Merced. Up until recently, I’ve been the only person on the project, however our recent increase in membership means Kybernetes will serve as an important resource for educating new members in electronics, sensor systems, localization, and mapping.

Nathaniel R. Lewis. TI eQEP Driver Tutorial. May 15, 2014. I’m using the am33x-v3.8 branch, which at the time of writing builds the v3.8.13-bone52 kernel. There are a plethora of tutorials on building the kernel, my favorite of which is Derrek Molly’s – https:/ www.youtube.com/watch? This video is a bit dated, but if you replace “git checkout am33x-v3.2 -b am33x-v3.2” with “git checkout am33x-v3.8 -b am33x-v3.8” the instructions are practically identical. We need to setup some boilerplate code at first.

Nathaniel R. Lewis. Using a Beaglebone with an HC-SR04 sonar. April 30, 2013. And this is what the setup looks like. The code on the Beaglebone side is a bit less straightforward. Unfortunately there is no higher level language available for the PRU than PRU Assembler. Oh well I suppose. The guide on how to use the sample code is here on my github: https:/ github.com/Teknoman117/beaglebot/tree/master/hcsr04-demo In the mean time, here is a YouTube video of my sonar code in action.

Please ignore the outburst of “ran out of power” in the video, I was jumping to conclusions since I was running on a two hours of sleep and countless cups of coffee. In the end, there were things that could have been done better, but I went home that day knowing that Kybernetes had done everything it was instructed...
