Simple sliding window moving average filter.
Essentially just takes takes the average of the last window_size values and pushes them out every send_every.
|
explicit |
Construct a SlidingWindowMovingAverageFilter.
window_size | The number of values that should be averaged. |
send_every | After how many sensor values should a new one be pushed out. |
send_first_at | After how many values to forward the very first value. Defaults to the first value on startup being published on the first raw value, so with no filter applied. Must be less than or equal to send_every. |
