    Joseph Wu
    Bo, 1. I've never use Matlab as an inteface for the serial port, are you sure you have everything from the RS232 side hooked up correctly? Have you verified it with an oscilloscope? 2. The Streaming command takes the data at what ever rate the board is set to. This is outlined on page 19 of...

    Philip, You can review the user guide to see how the device communicates through the serial port. Basically you can start a terminal program (like hyperterminal) and control the ADS1232REF in this manner. For example, you can setup the device, take a reading, and the reading will be displayed on the...

    Frank, What is the brand and model number of the weigh scale you are trying to use? Are you connected to the terminal block or the header. What are you using to power the ADS1232REF board? What value of calibrated weight are you using? Best regards, Bob B

    Phillip, Is the switch malfunctioning, or is it not responding in the way you think it should? When you press the TARE button, does the LCD flash TARE and then SETTLING? What is the weight you are trying to measure, and what does the LCD display? Also, can you tell me what the version number is...

    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...

    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...

    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...

    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. Best regards, Bob B

    Charles, It would also be helpful to know which version of the firmware is installed. You can verify which version by checking the LCD when the board is powered or reset. Also, there are two modes of operation. One is analysis mode, and the other is scale mode. The TARE button only works in the...

    Charles, I'm sorry, but I'm currently out of the office this week, but will be in on Monday. At that time I can set up a board with a load cell so that I can answer the question more specifically. In the mean time, can you tell me a little bit about your load cell and how it is connected...

    Bob Benjamin
    Charles, I'm taking a look at the switch commands now. One thing to keep in mind. The board is basically designed to be stand-alone, however if you use the software, the software may overwrite any commands that you have saved in flash. Usually if the inputs are just drifiting around, the inputs...

    Charles, Besides the obvious switch problem, I have verified that there are discrepancies with the user guide regarding the switches. We will need to update the user guide/firmware to reflect the proper operation. Thank you for your detailed input. Best regards, Bob B

    Omar, I'm only guessing about how you have this hooked up. Are you saying that you have an external processor connected to the ADS1232REF? Can you send a schematic or drawing of what you are trying to do? DRDY/DOUT is an output on the ADS1232, so I'm confused about what you call DataReady...

    Bob Benjamin
    Omar, That clears things a bit. How are you powering the components on the USB side and what position is the programming switch SW9? I think what you are trying to do is RESET the device from time to time. This is a bad approach. The TUSB3410 control signals are only meant to be used for the bootstrap...

    Omar, You are resetting the MSP430 processor if you use the DTR line. This is way outside of the scope of how this system is designed. You need to stay within the confines of how the system works. You cannot think of this in terms of normal RS232 type behaviour. There is no handshaking taking place...

    Omar, The firmware files are contained in a zip file on our ftp site: ftp://ftp.ti.com/pub/data_acquisition/ADS123xREF/ADS123x_CDROM/Firmware/Firmware_Source_Code/ The code is a bit hard to follow as it uses freeRTOS. That means there is task swapping going on. What you will be most interested...

    Omar, You said before that you received the echo....that means you are communicating, as the echo is sent from the MSP430 based on the data that was sent to it. In this case what happens is the UART receives the character, places it in a RX buffer (of one character size) and generates an interrupt...

    Jens, Unfortunately the ADS1232REF board has not been qualified to run on Windows 7. I'm not sure what you are using for the driver. If you are using the driver that was part of the installation program for the ADS1232REF, you may have an older TUSB3410 COM driver that may have issues with Windows...

    Hello Bob, Thank you for your rapid response. I did as you wrote, I updated the driver on another PC with WinXP. However I experience the same issue here. The ADS1232REF connection to the first two boards work (they map as COMX and COMY) but when I insert the next two boards then they become COMX...

    Bob, I understand, I will check if the USB ports I used were version 1.0 or 2.0. I will contact the support of TUSB3410. One final question, I was a little bit confused when you wrote that I was "...using the ADS1232REF beyond the scope to which it was intended". So what did I do...

    More Granularity
    Graham If I switch channels every sample, then it takes 12.5ms+51ms+12.5ms+51ms = 127ms per cycle. So I can sample each channel 7 times in my 1 sec interval, and that gives me the best sampling overlap between channels. If I want to maximize samples/chan then I should sample each channel for...
