Hi,

- what are the "autostop" variables in CMS: spd-avg-auto, time-t-auto ?
They stop to increment when the speed is 0 for some time ?

- is it possible to add two difference of altitude variables :
ie. when you start the CMS it takes the current altitude, then each time the altitude increase you increase the {alt-positive} variable, each time you decrease altitude you increase (or decrease) the {alt-negative} variable.

So when you go trekking you can have how much altitude you climbed and walked down during your walk.

Cheers,
Nibbler.

1. "autostop" - yes you are right
2. there is asc-t and desc-t but honestly: not really usable, I'm quite dissapointed with altitude accuracy on my LD-3W..

Idea Some variables that can be useful.

    Initial height
    Maximum height
    Minimal height
    Diff. of raise accumulated
    Diff. of descent accumulated
    Plain time
    Raising time
    Descending time


Consult the utility in this page.... http://www.ibpindex.com/ Cool Rolling Eyes

Oops, sorry, they are not supported, you will probably see 0 as the value.

I fully agree with x2fer ! Very Happy
Could you please add these variables in further releases ?

Exclamation As for the altitude, as it is less precise than distance an fluctuate quite a lot I would propose to add an averaging method for calculating it :

You could get all the altitude data from the gps for a minute and then you calculate an average altitude every minute.

Even better, you could add a configuration field "Average Altitude Period" where you could set in seconds the averaging period. (if you set it to -1 you get the altitude data from the provider "on the fly" without any averaging). Cool

Even, Even better ... Wink ...The averaging period could be calculated in a "sliding or shifting array" so instead of giving an average info every minute, each second you could give the average value for the "instant minus period" period. Rolling Eyes

Cheers,
Nibbler.
