Re: Private message regarding: [beagleboard] BBB Data Aggregation Unit using external ADC

[William Hermans]

Chelsea,

Basically, you have access to any libc library function, and any library
function you care to import personally. So, for the most part. You can get
a good book on Linux programming, and just follow along.

One thing I'm personally unclear on, is that if these libc headers are
already installed as base, or through the *build-essential* package. I
could probably find out, but never bothered because in order to write C /
C++ code you should install that package anyway. As it installs the GNU
Compiler Collection, and everything else needed to get started with C/C++
development.

Python, I could not say exactly, but I'm fairly certain it's roughly the
same. Just *apt-get install *

 Hi John,

 Thanks for getting back to me. I was actually looking at that same ADC
 converter as you posted in your reply. Just looking for some clarification
 on a few things. What type of error would a simple resistor divider
 introduce into the system? I am currently using a cascaded inverting
 op amp system. Not really sure if this will scale the input voltage to a
 level that is compatible with my ADC.

 The circuit diagram looks like this:

Hi John,

These are very helpful links. I was wondering if there was an online

etc.

 Hi everyone,

 I am new to the world of using MCUs and am looking for some assistance
 on a project that I am currently working on. To sum things up quickly, I am
 building a data aggregation unit that can convert analog voltage readings
 to digital values that is to be stored on a USB or SD card. The DAU will
 collect 3 types of signals, a buffer signal, clipped signal, and a signal
 passed through a LPF. In the end, the data should be stored as either a
 MatLab file or .xml file. However, I am facing a few road blocks relating
 to my design.

 1.) I need to use a 24 bit ADC for high resolution purposes based on
 design requirements that were just given to me as I will be collecting data
 from .1mV to 50V and it has to have a high sample speed rate. Has anyone
 connected an external ADC to the BBB? If so, what was the brand of your
 external ADC? How did you connect the ADC to the BBB? (It'd be greatly
 appreciated to be able to see a design).

 2.) If you have had a similar project to this, was wondering how you
 went about it. Any advice would be greatly appreciated.


 As I said before, all of this is very new to me. So thank you for
 taking the time to help me out.

 Chelsea

Hi Chelsea,

I have cc beagleboard because someone else might learn from this discussion. 
Looking at the link you provided, it won’t work because ADS1278 requires a 
differential input. Look at page 39 for circuits that will work for you.

Re: Private message regarding: [beagleboard] BBB Data Aggregation Unit using external ADC

[Chelsea Orefice]

Hi John,

Just wanted to say thank you for really helping me with this. It has been a
struggle for me and my team to get help from different resources at school
as well as our liaisons where we are getting our design requirements from.
(This is our senior engineering project.)

I am having still a little difficulty in understanding how the circuitry I
shared with you may give me a single input instead of differential that the
ADC requires.I attached the actual design of the system, so if you could
help me understand how it won't work it'd be much appreciated.

Also, may you tell me your background in relation to all of this? You are
very knowledgeable in this area, and when I relay some of this information
to my team I would like to share from whom I received this information
from.


Sincerely,
Chelsea

Also in the attachment, the parts labeled MCU will now be ADC. (Sorry about

 on a project that I am currently working on. To sum things up quickly, I am
 building a data aggregation unit that can convert analog voltage readings
 to digital values that is to be stored on a USB or SD card. The DAU will
 collect 3 types of signals, a buffer signal, clipped signal, and a signal
 passed through a LPF. In the end, the data should be stored as either a
 MatLab file or .xml file. However, I am facing a few road blocks relating
 to my design.

 1.) I need to use a 24 bit ADC for high resolution purposes based on
 design requirements that were just given to me as I will be collecting data
 from .1mV to 50V and it has to have a high sample speed rate. Has anyone
 connected an external ADC to the BBB? If so, what was the brand of your
 external ADC? How did you connect the ADC to the BBB? (It'd be greatly
 appreciated to be able to see a design).

 2.) If you have had a similar project to this, was wondering how you
 went about it. Any advice would be greatly appreciated.


 As I said before, all of this is very new to me. So thank you for
 taking the time to help me out.

 Chelsea
