Hi,
My name is Fisher, I'm doing a Masters in control system research and need
to choose a controller board for my project.
It will control a 6 wheel car (wild thumper) to keep a rod (inverted
pendulum) upright.

I had first to clean up lots of stuff (are they really needed in the
official Debian image? I think lots of apps (like Chromium) and graphical

Then I had

That makes perfect sense. Thanks Bas!

I just recently changed to a static IP on my Beaglebone black. I am trying

Currently running Debian Wheezy instead of Angstrom like I was doing
previously.
The link to the guide:
So, I have one of the PRU's toggling a GPIO output to create a ~50MHz
clock. On the 'scope I can see the voltage of the signal is ~0.8v not 3.3
when it's running more slowly.
This is toggling pin P8:11 (GPIO1_13) by the way, and I'm not sure if
there's any L/C on-board that is slowing it down.
I have directly interfaced the BBB with low cost camera modules using a PRU
on the TI AM335x. I have only tried using the parallel digital video port
(DVP) type of image sensor interface. I used PRU1 since it has a maximum
of 15 input pins available [PRU0 has a maximum of 11 input pins

Hi cowboy!
I confirm, GPIO high is 3.3V. Unconnected pins (input pins without
resistor) have about 0.8V.
Why don't you use the PWM devices for that task?
Anyway, P8_11 isn't connected to the PRUSS. This pin only works in GPIO
mode (mode 7) and I'm not sure if you can reach 50MHz that way.
You should really buy yourself a serial debug cable. At least that way
you'll have a way to get into a terminal.

You can reach 100 MHz to toggle a GPIO pin in open loop control. This is as
fast as the PWM devices. (When you need closed loop control it slows down a
lot due to the latency on the OCP port.)
