EVM430-FR6043: EVM430-FR6043: ERROR DToF - Shift value was greater than maxSampleShift

Hi,

 I have changed USS_ALG_MAX_SAMPLE_SHIFT to 80. now this error is gone but still performance is not getting as required. Please Check Code snap.

Hi,

What do you mean by the performance is not getting as required? Any test data you can provide here?

Best regards,

Cash Hao

Hi,

For your kind reference, we are attaching the details of the configurations and tests we have tried so far. 

Hi,

It looks like there is no valid receive signal captured by the ADC. There is just noise. What is the ADC capture looks like when there is no flow. 

Best regards,

Cash Hao

Hi,

 Please Find attached pic this is taken from no air flow or normal setup. And for your information that noise is (previous pic) come after air speed exceed 30m/s.

Hi,

    Thanks, As of  now PFA link which we are flowing same as show in mechanical 3D Setup, Pizos and MSP430-FR6043 EVM kit Configuration structure.

Hi,

But the amplitude of ADC capture signal can reach out to 800 ADC codes in that app note. There must be something wrong on the hardware side which cause the signal being weak. 

Best regards,

Cash Hao

hi,

    Yes, we will discuss on meeting for this.
