Re: [beagleboard] Re: pygame displaying on /dev/fb0 - Solved

2020-09-12 Thread jonnymo

Cool.

  I am unable to get your pygame or other fb examples to work but I can get
the 'usr' examples to work.

Perhaps this is for another post, but in your examples, are you using SPI0
or SPI1?  It seems some of the setup for the examples are set for SPI0 and
some are set for SPI1 yet the wiring listing in "EBC Exercise 12a 2.4 TFT
LCD display via SPI" seems to indicate SPI0.


Cheers,

Jon

Re: [beagleboard] Re: External USB 2TB HD not spinning up.

2020-09-12 Thread jonnymo

I vote for using a Powered USB Hub attached to the BeagleBone.  I've had to
do the same thing when using a separate Bluetooth and WiFi module and for
just basic USB expansion.   However, I found that not all Powered USB hubs
worked with the BBB; at least not so a few years back.

I did have luck with the Belkin P-F4U041 though:

Re: [beagleboard] Robooic Application in Beagle Bone Black

2020-09-12 Thread jonnymo

The Logitech C920 with OpenCV is a common combo with the Beaglebone Black
as far as cameras are concerned.

The BeagleBoard site has some Robotics examples but not all are for the BB
Black:
https://beagleboard.org/p/projects/tags/robotics

There is an example from Derek Molloy on his website/books using the
Logitech C920  however it is a bit dated:
http://exploringbeaglebone.com/chapter14/

The Packt book Mastering BeagleBone Robotics has an example using a
Logitech 720.
https://subscription.packtpub.com/book/hardware_and_creative/9781783988907/4/ch04lvl1sec21/connecting-a-webcam-to-the-beaglebone-black

  Here is an example using a Microsoft Web Cam which looks interesting.
http://einsteiniumstudios.com/beaglebone-opencv-line-following-robot.html

The Robotics Cape might be of interest to you for the motor control and
sensor section.

I'm sure there are more.

Re: [beagleboard] Re: External USB 2TB HD not spinning up.

2020-09-12 Thread Ren W

https://beagleboard.org/Support/FAQ

- *What power peripherals are required/desirable?* 
   
   - There are several ways to power a Beagle. The option exists to feed 
   the on-board regulators through either the 5V barrel connector input or USB 
   input. When powered up over USB, the regulators are somewhat limited in 
   what they can supply the system. Power over USB is sufficient as long as 
   the software and system running perform some management to keep it under 
   the USB current limit threshold. For simplicity and maximum capability, 
   powering over the 5V barrel connector is typically recommended.


   - The power adapter is required to provide 5V over a 5.5mm outer 
   diameter and 2.1mm inner diameter barrel connector (a barrel connector 
   length of 9.5mm is more than sufficient). The recommended supply current is 
   at least 1.2A (or 6W), but at least 2A (or 10W) is recommended if you are 
   going to connect up anything over the USB. The actual power consumption 
   will vary greatly with changes on the USB load.

Re: [beagleboard] Re: External USB 2TB HD not spinning up.

2020-09-12 Thread Dan and Ann Barber

A further note of interest. I experienced this problem when the BBB itself
was powered by USB connection to my laptop. However, I discovered that when
I plugged the BBB in with the power adapter, the external USB drive spun up
no problem.

Is this expected behavior? Just curious. Thanks for the pointers.

[beagleboard] Robooic Application in Beagle Bone Black

2020-09-12 Thread Megha Bhirade



Hi,
I am using Beagle Bone Black in Linux Ubuntu platform.

I want to develop the robotic application using Beagle Bone Black 
controller. application has navigation, tracking and obstacle avoidance 
features.

I want to know which camera is suitable for navigation in Beagle Bone Black 
and what are the additional tools and libraries required for this 
application?

Please suggest me any related link...

Re: [beagleboard] BBAI RTC

2020-09-12 Thread robert.sty...@gmail.com

The BeagleBone AI (BBAI) has the AM5729 system-on-chip.(which is part of 
the AM57xx series). The other BeagleBones have AM33xx series.

The AM5729 has a RTC peripheral built in. BUT, the BBAI does not have the 
necessary connections and components to use it.

If you need time of day, and do not have an internet connection to a time 
service, or a wake-up alarm; then you need an external add-on board.

Sorry folks if I'm asking in the wrong forum. I couldn't figure out how to 
tag the question as being for BB-AI.
