ADS1232REF: Data storage problem

Part Number: ADS1232REF
Other Parts Discussed in Thread: TUSB3410

Tool/software:

I'm using TI's reference hardware ADS1232REF and attempting to gather data from its conversions.  The software is loaded, I believe successfully, and the board is running and shows ADC conversion data on its on-board display.  I have selected a destination file location in the "Recording" section, and when I click on the Record button it creates the file as I've specified, placing a header in the file as such;

Speed=Slow Gain=1

If I change the gain or the speed it rewrites the file and updates this information with a new gain or speed when I change it. However I am seeing no ADC data collected, although I do see the ADC conversions on the on-board display on the reference board.  It seems to do this whether the board USB cable is plugged in or not, so I'm assuming it's a connection problem.  I've gone through the steps in the TI document "ADS1232REF Users Guide" section 4.3, but I can't seem to get any ADC data written to the file it creates, only the header information.  Th "Status" indication in the lower right of the display window initially says "scanning", until I press the "Record" button, then it changes to "idle".

    Hi Scott,

    Welcome to the E2E forum.

    Did you see the D1 green LED was turned on? Did your GUI look like the following screenshot? If not, you probably did not plug-in your USB cable into your PC or laptop or your USB cable was not good and you need a new USB cable.

    BR,

    Hi Scott,

    I installed the GUI software on my laptop yesterday which was the first time installed on my laptop (Windows 10), the GUI was successful to capture and show the data. Did you try another USB cable or another laptop/PC with admin rights if possible? could you provide a screenshot for Device Manager on your  laptop/PC? 

    BR,

    I guess you're not getting my replies when I reply to your email?  Shall I only reply on the forum on your web? 
    Here is what I'd said in my email...


    The USB cable is plugged in, I’ve tried two cables – the one that came with the board, and another known working cable. 
    There is no “D1” LED on this board, however there is a “D2” LED that’s lit.
    The SW9 selector switch is in the “JTAG” position, is this correct?  I’ve tried the “USB” position as well however with no difference.  The PC software “Status” indication says “Scanning” continuously. 
    This seems to be a USB connection issue, so need suggestions of things to try to allow it to connect. 
    The "D2" LED comes on when I plug in the USB cable. 

    I've attached a screen shot of the device manager, seems an "Other Device" is connecting by the name of "TUSB3410 Boot Device"
    The "D2" LED lights when I connect to the ADS1232REF board.

    I will try on another computer.

    Hi Scott,

    I did not see your replies, please keep communicating in this thread on the E2E forum.

    • It is D2, I apologized for my typo. 
    • SW9 can be used to update the firmware on MSP430 through USB interface. Normally this switch is open (to JTAG PROG which is actually not install on the EVM); it is only switched on (USB mode) when the firmware is to be downloaded through USB, so just keep SW9 to JTAG PROG position.

    It seems like the TUSB3410 driver on your computer was not properly installed because a '?' mark is shown before TUSB3410 Boot Device line in your device manager. After you complete the ADS1X3X setup wizard, you should be able to see a pop window as shown below, please select 'No' to reinstall the TUSB3410 driver.

    Also, please see my device manager below, the software and EVM worked as expected on my laptop.

    BR,
