So I thought it would be useful to be able to use your calc as a stopwatch, so I made this utility for the CE.

Source code and .8xp file available here....

I might add other features (such as lap times) if enough people want that.
Thanks.
I like it Kotu. Does this use the calculator clock itself for maximum accuracy? Because this could be handy when you can't use your smartphone or don't have an actual stopwatch with you
It uses the 32768 Hz clock.
I really like it, lap times would be cool as well :thumbsup:
btw... why don't u ues the same button for Stop and Pause...?
U sure donä't want to do it both at once ;D
i prefer it like this ;)

err, don't see how this affects you as you don't even have a CE..... so.... not good enough reason to add it :thumbsup:
I don't mind the controls actually. I had watches where you used the same button for start and pause and others where two buttons were used.
Just updated the repository - the program now runs at 64 fps instead of 32 fps.
ok some news regarding this
i ran my calc for 8 hours to determine the accuracy of the "32768Hz" clock. it came out around 6 and a half seconds slow. i determined the actual frequency of the timer on MY calc is around 32760.73 Hz
this is not actually a problem as you can rebuild the program to suit your calc. this WILL make it more accurate, but obviously the closest you can achieve will always be an integer (in my case it would be 32761)
ok bye
*edit*-
in this example it would still be around .24 seconds slow :(
if you get less than a second error after 8 hours... I dont think lots of people would care about such a tiny mistake ;)
sounds good enough to me :)
the thing is though p2 I intended for this to be used in Formula 1
:'(

I think even F1 doesn't have enough money to use TI calculators as clocks :c
That's not too bad I would say. Still very close to accurate.

^this. so much!
Yeah I agree that those are friggin' expensive clocks. :P
Jeremy Clarkson just kicked my head in
it looks good :thumbsup:
that's due to
@MateoConLechuga 's work ;)
i mean thanks
currently testing accuracy again - this time with a 32761 Hz cycle
plus changed the colours......

Until it has a thousandths place, I deem it obsolete.
But seriously, it's really good!

they use it for F1
Good to see updates.
Just done a 6 hour test, it was 0.2 seconds out. Pretty much what I was expecting :D
Good actually for a stopwatch. :3=
Extremely. I'm assuming there is no way for you to have the stopwatch self-adjust to the speed of the calc it is running on?
If it did, this would be a much better (is that possible?!) program!
:(
i don't have the assembler knowledge to do that i'm afraid
