TimeTools
« on: November 14, 2010, 06:06:48 am »
TimeTools is a small TI-BASIC program I've been working on for a while. It displays the current time (both digital and analog display), and also has a timer that has the ability to continue even when TimeTools is not running. It only runs on TI-84+(SE) since the clock is used.
I've tried to optimize this as much as I could. The screen is only updated when needed, and the whole program is about 1 kB. Usually, it runs at about 5 FPS.

The hands are done via sin( and cos( in degree mode.  At zstandard, Lsin(A) gives the y coordinate for a hand L long and at the angle A.  A goes from 0-360, so for the second hand, it goes 60 times in a minutes or 360 degrees, which means it goes 1 time in a second or 360/60=60 degrees.  Also note that the pair (cos(0),sin(0)) produces (1,0) which means that you are going to have to shift the degrees by 90.  So that way, at 0 seconds, it would be (cos(0+90),sin(0+90)) which is (0,1) the correct start of the clock.  To have an offset, just add the x and y coordinates outside the sine and cosine.  Also note that that click will go counterclockwise, so you must negate the entire angle measure inside the cos( and sin( brackets.  Good luck. I would try a simple clock the size of the screen first, though.

Actually, that would make it go backwards (counterclockwise). An easier (and smaller) way to do it is sin( for X and cos( for Y.

This project looks pretty nice, especially for a first project. 5 FPS is a pretty good speed for BASIC :D

Interesting, I'm curious how this will turn out. :)

I've managed to draw the hands of the clock, but everything isn't done yet. I need to make the hands I drew the previous minute disappear, and some other stuff :P
Is it possible to recall a Pic when in Horiz mode? It doesn't seem to work for me.

It should work, but it only shows the top half. The bottom half gets cut off, unfortunately.

Looks great, so, we need to set time i the 'Mode' button before using the program?

EDIT: Just tried it in Wabbit, yes we do, indeed, maybe add an option for us to set time, if possible?

EDIT2: Also, it displays "ednesday" instead of "Wednesday" :s

If you want to set the time, then you can use the setTime( command in TI-OS. It takes Hour, minute, and second as the arguments. You might just want to trim it to Hour and minute.

I prefer to go to Mode :), it's much simpler and lets tou set date format and everything!

This looks better in my opinion :P

I see how you have decent timer controls in there, great, becuase I used to have to make a BASIC program every time I wanted to use a timer function.  And even then, that timer isn't fully accurate.

Great work so far!  Keep up the great work!  When it's finished I will probably put it on my real calc too ;)

NOOO I DON'T HAVE 666 POSTS ANYMOREZ :( I HAD THART FOR ONE WHOLE DAY TOO :P

EDIT: and 5 fps is fine for a BASIC prog.  if it were asm however, we'd be expecting a fps of >9000.  ;)

The setTime( and the SetDate( functions are the same ones that TI-OS uses in the Mode menu :P

I fixed the ednesday glitch earlier today (didn't notice it earlier, because the current screen erasing routine was written on Thursday last week...) The fix isn't uploaded yet, though (TI-Connect refuses to connect with my calc right now).

Also, adding an option to set the time might be a bit tricky. The code is not designed for going to a second screen while the program is running and then go back, but I'll see if it's possible to make something anyway.

Great, hope you can make it, though!

This looks cool.  Good luck getting 'settime' to work. :)
