ADS1232REF - Beginner Question

Other Parts Discussed in Thread: TUSB3410, ADS1232, ADS1232REF

Hello all,

I am running Windows 7 professional 64-bit and trying to install the ADS1232 software with Labview Runtime. The installation seems to run well and the README instructions were followed; however, it does not install the USB serial port drivers properly and I cannot get the board to connect and be recognized by my computer. Currently in device manager it shows up as TUSB3410 Boot Device.

I believe the basic problem I have is to just get the drivers to install. I would certainly install the drivers manually but I cannot find which drivers I would need to install. Any advice would be greatly appreciated.

 

Best regards,

Atley

    Atley,

    Unfortunately the current version of the software will not run on Windows 7.  This is a limitation of the development version of Labview that we have been using.  There is a version of the software that will run with Vista/XP and it can be found at:

    ftp://ftp.ti.com/pub/data_acquisition/ADS1x31REF/Software/

    This would be the 1.3.1 version.  We will be having a version compatible with Windows 7 sometime next year, but at this time it looks as though it may be mid-year.

    Best regards,

    Thanks very much for the quick reply!

     

    I've given up on 7 and installed the software and drivers on a Windows XP system.  Now I am trying to figure out how to flash the firmware with my own version. Any suggestions?

    I've run into a software called mspgcc (http://mspgcc.sourceforge.net/) which seems to work but I don't know the "default password" to access the flash memory. Sorry about these elementary questions but the User's Guide that game with the board is not very comprehensive.

    Atley,

    Flash your own version???  You mean C code to the MSP430?  Are you expecting to use the Labview code with your own firmware?  We use freeRTOS to maintain a specific timing relationship, so depending on what you are doing you may run into some issues.

    On the right side of the ADS1232REF is J3.  You can attach a JTAG programmer to this connection.  We have devised this connection to accept a dual row, through-hole header.  In this instance the header is placed on the side of the board and the pins soldered on top and bottom.

    Best regards,

    We will be modifying the source that came with the board, which uses freeRTOS. We are able to build the firmware and want to be able to upload the firmware to the board. What is the best way to upload?

    We are getting password error when we upload with msp430-bsl,exe. The firmware updater is working fine. We don't know what the default password is or how to create one.

    Look forward to your response.

     

    Thank you,

    Atley

    Atley,

    There is no password. You may have a power or power sequencing issue.  USB only powers the USB section unless SW9 is in the USB mode position.  I'm assuming you are using a JTAG FET adapter.  That is the easiest and fastest way.  If you try to use the BSL via USB, that is a little more difficult.  In this case the SW9 switch needs to be set to USB mode (to the right.)  We have found that when using the USB as a COM port it is better to use the lower COM values, such as COM1-COM8.  Sometimes the installer assigns this to a much higher number.

    Let me know which method you are trying to use, and maybe I can be of more help.

    Best regards,

    Bob,

    Thank for your response. This is what we are doing:

    When we load the TI firmware using the firmware updater in USB mode as instructed, it works fine as shown below. As can be seen in the window, it seems to transmit default password.

    However, when we use msp430-bsl.exe to upload the firmware we built, using the switch in USB position, it seems to fail due to password error as shown below:

    When we did the same thing with switch in JTAG prog mode we are getting "Bootstrap loader synchronization error" as shown below:

     Could you please let me know the right procedure to load our firmware? Can we use our file with the firmware updater (ADS1232REF_Firmware_Installer) provided by TI?

    Thanks again for your prompt replies as this is a time-sensitive project.

    Atley,

    Try adding the switch '-epvr' to your command line.  This will erase the current memory, use the default password, verify the upload, and reset the device.
