hello everybody,
i have one (maybe trivial) question.
In cf python codes i always see the reset kalman estimation done by these to command
cf.param.set_value('kalman.resetEstimation', '1')
time.sleep(0.1)
cf.param.set_value('kalman.resetEstimation', '0')
my question is...why one needs to switch the value of kalman.resetEstiation variable to 1 then to 0?
The default "working value" is 0 and in order to reset one has to switch to 1 and then bring it back to the working value. Am i right?
Thanks
Gianni

The reset command is active on rising edge, so setting from 0 to 1 resets the kalman filter. We set it back to 0 so that next time you run the script it is reset again.
