Arduino Computer - FrostAPC328

Synopsis:
The FrostAPC-328 is a clock that will also be able to run apps. The device has a 16 character, 2 line LCD display and is powered by my Arduino Uno. It has 3 buttons: Scroll (B1), Accept (B2), and Exit (B3).

A video:

Some pictures:
Here's the device itself.

Here's the main menu.

Here's the clock. (It's not set yet!)

Here's the stopwatch. It's really simple. Scroll starts/stops, and Accept resets.

App support isn't implemented yet, so I can't show any pictures of that!

Here's the settings menu. All of the options actually work here!

Here's how to set the time. Scroll changes the number, and Accept continues to next field.

Here's how to set the date. The controls are the same as setting the time.

The System Info screen only shows version number. When app support is implemented, it will show free memory.

What will the operating system be able to do? Does it have a filesystem or multitasking?

Don't expect much.

There will eventually be a filesystem, but it will be extremely simple. Probably just files, and no directory support.

Them TI-8x fonts ^.^

Nice so far by the way

That's just the default font of the LCD. If you search the driver chip this LCD uses on Google, it looks like they all use the same font.

Yeah pretty much every cheap character LCD module uses one of those or a clone. It's an industry standard.

TI must have sent a lot of DMCA takedown notices or C&D letters in recent years, then >.<

Kidding aside, thanks for pointing out. I didn't realize those fonts were standard on those LCD's.

They look too alike the Casio font, you know? Just everything low-res have a similar font.

Oh and IIRC copyrights can't be applied to bitmap fonts for a reason I don't remember.

indeed. They look even closer to TI-84+ and 89T fonts though
