EVM430-FR6043: To increasing the sampling frequency of Delta_TOF

Cherry Zhou

Part Number: EVM430-FR6043

Hi team,

Customers are now evaluating the gas ultrasonic flow module using the EVM430-FR6043 platform. The Delta_TOF sampling frequency of 150 hz is required in real-world applications and can currently be set to only up to 20 hz with USSSWLIB software debugging (the minimum time from UPS0 to UPS1 can be set to 50 ms extrapolation).

Issue: the customer would like to know why the minimum limit is 50 ms. The initial assumption may be that the soft run time is large, so what is the actual operating time of the hibernate wide and is it possible to optimize?

Could you help check this case? Thanks.

Best Regards,

Cherry

Hi Cherry,

If customer would like to reduce the algorithm run time, they can try to decrease the num of pulse.

But for 150Hz, need run all USS function within 6.67ms, I think this is very difficult.

We did some test, if we reduce the num of pulse, the time can be as low as about 12ms。

Thanks!

Best Regards

Johnson

Hi Johnson,

Thanks for your support!

And since the customer has some additional questions, would you please response to them on e2echina forum directly?

Thanks!
