Oh yeah I also have another question: is it possible to create a waveform display of the analog sensors through python? Since I have the idea for reading voltages, I was wondering if its possible to create a sort of waveform with the x y and z axis. For that I think there should be a separate

A quick question @Mike Bremford: since I have a code for reading the voltages from the accelerometers, is there a way to create the waveforms in python? I was just wondering if its possible to make a waveform, but i think that will be another program code for it. I'm just not sure how to do it.

Quick Question @Mike Bremford: Do you know how the digital accelerometers will be reading on the beaglebone black's I2C pins? I haven't had much luck finding any examples for a program code. On Sat, Nov 9, 2013 at 4:48 PM, Mike Bremford m...@bfo.com wrote: Nice of the other team to leave you

If they're analog, surely you'd just hook them up to the analog pins and read them the normal way? Probably with a couple of resistors to reduce the voltage range to 1.8V? http://learn.adafruit.com/measuring-light-with-a-beaglebone-black?view=all Out of curiousity is there a reason you're using

Hello Zain, I'm no help on the coding, but would like to answer your question on resources for learning more about BeagleBone Black. Best place to start is the http://www.beagleboard.org/ getting started link. Plug in your board first to see the tutorials. Both of these books are available

Thanks Cathy for the help, I have been using the beaglebone getting started link and have been trying out the examples, they have been a great help with the tutorials. As for the ebooks, il think about it, but thanks for referring them to me. Prof. Molloy's tutorials have also been helpful, I'll

Nice of the other team to leave you no documentation... I guess if I was stuck with 12 analog inputs and only 7 pins to read them on I would use something like a 74HC4051 to multiplex the inputs - use 3 gpio pins to control which of the 8 inputs is connected to the ADC on the BBB. Or use an

I know, I felt really annoyed that the Prof who provided the brace was not so keen on how it was tested... yet provide at least a history report on it. If the inputs of analog sensors require an extra chip, then I will need to look around for the chips mentioned in the previous post. Thanks alot

Well I was thinking of choosing python because of its ease of use for pin manipulation and when I first got the beaglebone, I was setting up the python library. I wasn't sure how to do it in other languages because I don't have that much experience. As far as C++ is concerned, I do know a
