Distance calculation ?

[RixtronixLAB]

Dear Members,

How can I implement this formula

into a code with timer ?

I get the speed (V0 and V ) from the sensor every second.

Any ideas ?

Thanks

I want to get the distance but the speed is changing within time, please have a look on my xls spreadsheet attachment, Total distance in 5 seconds.xls

How can I implement it in C with timer and array of Vo and V ?

Thanks

Hi,

I can't write the code for you. Did you check timer tutorial I linked? It should be fairly straightforward to type it in if you get a grasp on how the  app timer library works.

Something like:

1. Start the timer and retrieve the start speed V0 from sensor
2. Stop the timer and retrieve the end speed V and the time elapsed.
3. Calculate (V0+V)/2 and multiply it with t
