Recording raw data with ADS1118 EVM

Other Parts Discussed in Thread: ADS1118EVM, ADCPRO

Is it possible to record raw data using the ADS1118 EVM (such as to a .csv)? Using the Labview app you can 'copy data' from the graph, but that just takes a screen shot. 

Thanks!

    Sima,


    The ADS1118EVM was not designed to record and store data. It only takes the data and plots it. If you need to be able to record data, you may be able to use a logic analyzer or maybe a Total Phase Beagle to check the bus transactions and record the log file of the data.

    If you want a similar EVM to record data, the ADS1115EVM has that capability through ADCPro. It has similar features, but it does not have connections to take a thermocouple.

    Hi Joseph,

    Thanks for the suggestions, but using a logic analyzer seems like overkill for this device.  Since the labview source code can be downloaded, I got a free trial of labview and hacked in writing to a .csv (helpful links 1 & 2). I removed a few delay functions in the program, but I still can't get a data rate more ~1SPS.

    Originally I wanted to use the specific ADC on this EVM, but in the interest of time I'm going to abandon this effort and use some other data logger.

    Thanks for the support.
