EVM430-FR6043: EVM430-FR6043

Dear TI,

Good morning!

Please help me to find out the solution of below problems.

1) "DToF -shift was greater than maximum sample shift" 

This above error is displaying again and again. Please help me to overcome this issue.

Although, I have been tried to change the "USS_ALG_MAX_SAMPLE_SHIFT " value from 20 to 40 in source code header file " USS_userconfig.h "  to escape this error. 

2) My flow tube is L-shaped and have one reflective surface inside the tube. I have used Audiowell 200KHz ultrasonic transducers and propagation length between both the transducers is ~135mm.

    Please help me to overcome the issue of instability of volume reading on EVM6043 and also the ADC value as shown below figures.

    Hi Vijay,

    Please increse this para and test again:

    And I think you can also try decrease the distand between T1 and T2, when you get normal ADC waveform, this error will disappear.

    Thanks!

    Best Regards

    Johnson
