Binary/BCD clock

Here's a simple binary/BCD clock. Graphics are embedded in the program, so there's no separate resource upload.

Enjoy!

Awesome! Would you mind if we grabbed a quick video of this and threw it on our blog? Attributed to you, naturally.

You're welcome to post anything you want.

I also used the same license as your source code, so you're also welcome to do whatever you want with the code consistent with the license.

How do you generate the code for the inline images? I'd love to do this for some of the smaller ones I'm using.

The LEDs were originally done in Flash for this Chumby widget. Since if have the original FLA, I modified it to see what it would look like at inPulse resolution and resized and placed the assets accordingly. I then had Flash export the two LED graphics as PNG. I brought them into Photoshop to "posterize" them to reduce the number of colors since the original range was silly.

Of course, these graphics could be done in any drawing program - I just happened to have them already in Flash.

I then went to an online image conversion site and converted them to XPM, which basically turns them into C source code. You could use them as-is with a little coding, but for efficiency, I made the color selectors in a contiguous range and rearranged some things a bit for better use with the inPulse SDK. I did that by hand for these (just find/replace and some trivial editing) - if I do it again, I'll probably throw together a simple script.

It seems like a lot of steps, but it only took maybe 15 minutes, and could be automated with little effort.

Here's a quick video of your wicked app, Duane! I've been wearing it all day, finally getting the hang of reading it before the timer times out!

Pretty cool. Glad you like it.

I'm not really sure the LEDs should look that realistic - it makes your nice OLED display and ARM7 look like 3 cents worth of cheap LEDs and a couple of flip flops.

Yes, but with a few tweaks, your binary watch could have notifications zooming to it! That's something pretty special...

Very neat - my son just told me he wanted a binary watch so I couldn't help but to show him "mine". Very nice job. Now if this could be combined with notifications, that would make it perfect

Maybe I'll work on this since I already got the analog watch combined with notification.

Hey Duane - make sure to post this app on http://www.inpulsewatch.com or I can as well of course

- Sorry can't help but to truly love this app! BTW - does anybody know why this app doesn't display correctly in the simulator? All images are shifted. Is there a fix for this? It does of course run great on my watch.
