MSP430FR6047: MCU018

Part Number: MSP430FR6047


Tool/software:

Hello,

While going through USS libraries for MSP430FR6047 for time of flight calculation, there is limit of 20 percent at threshold index. This limit is checking that if current  ADC value at threshold index is within 20 percent of the previous ADC value at threshold index then it will calculate the time based on this index only. The code will go to searching algorithm only when this 20 percent limit is violated. So what is the purpose of this 20 percent limit? What if I do not use this? 

Thanks,

Anup Kumar.

    Hi,

    Do you mean the USS_ALG_MAX_RATIO_PEAK_2_PEAK_VAR?

    The purpose is to save power. In water meter application, the receive signal is usually changing smoothly. It could help algorithm to save power using this method. If you do not want to use it, just set this parameter to 0.

    Best regards,

    Cash Hao
