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

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 inst

Hi John, These are very helpful links. I was wondering if there was an online document on all functions that I can code BBB in either in C, C++, python, etc. Thanks, Chelsea On Thu, Dec 3, 2015 at 11:12 PM, John Syne wrote: > Hi Chelsea, > > Here are some reference I have found helpful: > > >

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

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. Regards, John > On Dec 3, 2015, at 3:52 PM, Chelsea Or

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

To start with, the ADC that will meet your requirements: http://www.ti.com/product/ads1278 This is a 24 bit ADC sampling at 144kHz. To sample 50V, you will need a signal conditioning front end that will scale your input voltage to a level compatible with you

[beagleboard] BBB Data Aggregation Unit using external ADC

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. T
