ADS124S08EVM: Delta Sigma EvaluaTIon Software: How to save data without Data analysis tab

Part Number: ADS124S08EVM


Hello

I'm collecting data from the ADS124S08EVM with the Delta Sigma EvaluaTIon Software. 
This works perfect for short measurement, unfortunately for overnight measurement with higher number of samples the software stops working when trying to open the data analysis tab. 

Is there another way to access and save the logged data? Can i collect data using another method? 

Thank you in advance and best regards
Michael

    Hi Michael,

    The biggest issue with data collection is with the memory structure in the GUI.  We had initially hoped that we could have collected large sample sizes, but from our testing we appear to be limited to about 200k to 250k samples.  We will be moving away from the current GUI in about a month or so.  Because of this all bug fixes and development of the current GUI has stopped.

    The data file can only be saved once the data has completed collection.  If the memory becomes corrupted, then all previous data will be lost.

    I am not the one testing the new GUI, so I do not know if the length of data capture has improved.  At this time we do not have documentation regarding usage outside of the GUI.  I would suggest that an external processor be connected to the J3 digital connector and the onboard Tiva processor be disabled.  In this way data can be collected over any length of time or number of samples required.  The J3 digital connections used are shown in section 3.2.3 of the ADS1x4S08EVM user's guide.  You can use the USB power if you hold the Tiva in a reset condition.  This will prevent the level shifters from enabling and allow connection to the J3 connector.  The Tiva can be held in reset by adding a shorting jumper at JP1.

    Best regards,
