Installing a Wristapp
Many people have asked how to install a Wristapp and download it to your
watch. While there are people who aare using their DataLink with many
different operating systems, these instructions only work for the Timex Data
Link software for Windows (what comes on the floppy disk with the watch).
Note that this is different than Schedule+ or another PIM downloading
to the watch.
Locate the directory where the datalink software is installed. Typically
this will be C:\Datalink or C:\Program Files\DataLink. In that directory
will be a file called TimexDL.DAT
Using your favorite editor (Notepad will work just fine), bring in that file
Search in the file for the [WristApps] section. It will consist of
several lines like:
Note the number in the WristAppTotal and increment it by one. (In this
case I would change the 10 to an 11)
Go to the last entry and add a new line just like the ones above it, but
increment the WristApp number by one. In this case, I would add a line
after the WristApp009=endoff.ZAP and call that line WristApp010=. Put
the name of the wristapp (don't forget the .ZAP extension) on the line. In
my example, it would look like:
Save the file
Copy the .ZAP file into the APP subdirectory of the datalink software and
you are done.
Load up the Datalink Software, and click on the WristApps button.
Scroll to the bottom of the list to see your new WristApp
Select the wristapp and make sure that the bottom says to send the selected
Select OK and then proceed to download to your watch with the normal COMM
The wristapps that I have written so far. Everything here works for
both the 150 and the 150s.
Other People's Wristapps
It is wonderful to now see other people creating Wristapps.
NumPad - Michael
Polymenakos <firstname.lastname@example.org> has created an excellent app which has
two functions in one. In his own words: "The first thing I miss from
my old (and now non-functional) Casio is the ability to record a number quickly
when pen and paper are not available. I wrote a small wristapp, NUMPAD, to
let me record a 12 digit number... Any comments will be appreciated (especially
on replacing the ugly cursor with a 'blink' function that blinks only one
digit at a time)." He has also incorporated a chronometer wristapp
in with the app to give you two apps in one.
3Ball - Wayne Buttles
<email@example.com> created the first version of this fun app. It's
been updated here as a tutorial.
Plans for Wristapps
The wristapps that I plan to create and know everything necessary to create
WestMinister Chimes - For that 'Big Ben' sound. With thanks
to Pigeon for the sound scheme to make it possible.
Other wristapps that have been suggested (their original comments are
presented. I also include my comments in
Falling Blocks - I have been thinking about this for a while.
There is really no reason that you can't design
a game to take advantage of the segments to do a simple falling-blocks-like
game. You would have to turn the display sideways to play it.
Slots - I have also wanted to do this game for a while.
The basic idea is to have a slot machine in the
watch where you can press a button and take a whirl. The watch should
keep track of your winnings. Because of the way the segments are
organized, I believe that you can even do a good imitation of the wheels
Dumper - We need to have a good application that allows the Datalink
to talk back to the PC. The obvious way here
will be to use the sounds on the watch and listen to them with the
soundblaster on the PC. Right now the only thing holding us back is
someone to create the PC end to listen. I have everything necessary
to generate the tones in a predictable manner.
Phone Dialer - The Datalink is just screaming for this
application that has been suggested by many people.
It is not clear that this is beyond the capabilities
of the datalink, but so far I have only been able to emit the 14 basic tones
in the watch. From my experimentation, I am not convinced that this
is possible due to how the sound hardware is implemented.
Info entry - "One of the reasons I like the DataLink is because
it DOESN'T have an ugly 12 button keypad on it, but I have to admit, it would
be nice to be able to enter a phone number when needed. Granted, it would
cumbersome to enumerate the desired digits, but I think it would still be
useful (could also be used to enter the section # of a large parking lot
that you left your car)." David M. Schreck
<firstname.lastname@example.org>. This is certainly
doable, but it does have some issues to be considerd in dealing with the
EEProm. See the
EEProms information to understand why.
Screen Saver - "Not in the true sense of the phrase, of course,
and this one you would have to purposely invoke. I imagine that those who
are artistically inclined might think up a creative and interesting way to
cycle through the available display fields." David M. Schreck
<email@example.com>. If someone
proposes a suggested way that this might work, I certainly could implement
Baseball counter - "This might be too simple to bother with, but
people who are umpires (I'm mainly thinking about the many folks who ump
for little league games) use a little hand held clicker to keep track of
balls, strikes, and outs. This should be an easy applet to create." David
M. Schreck <firstname.lastname@example.org> This
is one where I would love to hear from someone who would actually use it.
I have a number of ideas for user interface, but that would really
depend on how someone would use it.
Tennis counter - "Say I'm about to start a tennis game. I hit
one button each time I score a point, and a different one each time my opponent
scores. The applet always displays the current score. It might even display
the word "deuce" when appropriate. Hopefully it could be programmed to be
smart enough to know when subsequent games begin, and even keep track of
the set score." David M. Schreck <email@example.com>.
Here is where I will let my lack of knowledge of
tennis show. I simply don't know how the scoring works well enough
to write this. I would like to have the person enter the two names
of the people playing and it woud keep track of who has to serve, the current
score, and the total match/set score. If someone would toss me this
information, I could create the app really quickly.
Calorie Counter - "If someone wanted to keep track of their caloric
intake for the day (or any other need where you want to tally up a total
but don't feel like carrying around a paper and pencil) perhaps they could
just punch in the number to be added to the daily total each time they eat
something. At the end of the day they can glance at the total and then reset
to zero. David M. Schreck <firstname.lastname@example.org>"
This is probably one of the more intersting apps to create.
I might even take advantage of the EEProm to store some of the basic
foods and their calorie counts to make it easier.
