EVM430-FR6047: Setting up parameters

Danilo A.
Mastermind 24715 points
Part Number: EVM430-FR6047
Other Parts Discussed in Thread: MSP430FR6047

Hi Team,

We would like to ask your help regarding the customer's inquiry below.

We are experimenting with different methods for flow metering.  We have run the evaluation board for the MSP430FR6047 (EVM430-FR6047) using the PC evaluation software.  The flow vessel body is non-conventional,  it has a double elbow at both the inlet and outlet.  This causes some amount of flow turbulence by the time the flow gets to the transducers.  The transducers are 2MHz and the pipe size is ¾”.  The evaluation board works well at low flows, but at about 14 GPM and above, the MSP430FR6047 does not track flow.  The ADC continuous capture display shows a large amount of amplitude variation.  Up and down stream amplitudes are somewhat different.  Are there any type of parameter configurations to help with the high flow condition?

Regards,

Danilo

    Hi Danilo,

    You can find a parameter called maxsampleshift in the USS_userConfig.h. The default value is 20. You can change it to 40 or 60 and try with it.

    Hi Cash,

    We have received this feedback from our customer,

    I loaded the example “FR6047_USSSWLIB_template_example.out” from the Resource Explorer onto the EVM430-FR6047 evaluation board, overwriting the demo code on it. Apparently this new example is not compatible with the Ultra Sensing Design Center interface, since now the interface no longer responds to the evaluation board. I reloaded the image of the original demo code "UltrasonicWater FR6047_02_04_00". There is no way updating the configuration header file for this demo code since all that is available is the hex image. It would help us with our evaluation if you can send two new image files of the demo code with the parameter USS_ALG_MAX_SAMPLE_SHIFT set at 40 and at 60. We are attempting to specify this chip in our new product line, but need to get this working. Thank you.

    Regards,

    Danilo

    Hi Danilo,

    The template example code do not have the communication function to the Ultra Sensing Design Center (GUI). The customer can use CCS or IAR to build the project and change the parameter by themselves. There are some other parameters they might need to change based on their application which can not be set by the GUI. I would not suggest the customer directly use the image of the original demo code.

    Best regards,

    Hello Cash,

    I loaded the example FR6046_USSSWLib_template_example onto the evaluation board that outputs on UART.  TeraTerm serial reader does connect to the output, but all that is outputting is zeros, in the form  %,00000000   !,00000000   $,00000000  #,00000000,  even with flow.  How do I get it to output proper data?   Thank you.  Vince

    Hi,

    You still need to edited the code then download it to the board and get the right data.

    Hello,

    I have edited the code and now it outputs.  I am currently on a low velocity flow loop.  Next week I will test on a high velocity flow loop to determine if the adjusted value of  "max_sample_shift" actually works.

    HI,

    It should work. Wait for the good news.

    Hi,

    The evaluation board was tested on a high velocity flow loop and it is now outputting,  allowing  us to continue data collection.  Thank you for your help.
