MSP430FR6043: Regarding the parameters in the 'Ultrasonic Sensing Design Center'

Hi,
Both refer to variables used to start or turn on specific modules in the FR6043. The PPG seems to be for optimum sensor excitation and accurate impedance matching to deliver the best results for ZFD. The ADC seems to be for signal acquisition. You can also refer to Tables 3-3 for a description (image below.)

Dear Diego

Thank you for your reply.

I understand it as shown in the attached figure. Is this correct? If there are any mistakes, I would appreciate your feedback.

Hi,
As I understand it, Tprop should be larger than the Start PPG Count since Tprop seems to have a larger time value. Moreover, the start of PPG should be larger than the ADC turning on (based on the recommended values I see in the text.)

Dear Deigo

Thank you for your reply.

In the timing chart, what does Tprop indicate? How is 'the start of PPG should be larger than the time when the ADC turns on' represented in the timing chart? Could you please illustrate it with a diagram? Thank you very much.

Hi,
The timing gram seems to be different of what I can see in the image you shared. Would you mind confirming with me you're using the TIDM-02003 Design guide (Rev. A)? And if not, would you mind sharing with me the document you are using?

Best Regards,

Dear Diego Abad

Thank you for your reply.
I apologize for the confusion. I will share the timing diagram again.
The TIDM-02003 Design Guide contains a timing diagram in Figure 2-4. However, I cannot find a more detailed timing diagram than this. The timing diagram in the image I shared was created based on the descriptions and experimental results found in "SLAU720B Ultrasonic Design Center." I am not confident that the timing diagram is accurate, and it may contain errors.
Regards.

Dear Diego Abad

Thank you for your reply. I will start a new thread.

Regards.
