QR Clock

Postby Markus Gritsch » Tue Feb 26, 2013 3:31 pm

Hi,

being inspired by ch00ftech's QR clock [1] I made my own variation of this nice idea: A PIC32 decodes the time signal from a DCF77 [2] receiver, calculates a QR code containing this time information, and displays it animated at 30 FPS on a ST7735R LCD. Without a radio signal the QR code is being displayed in b/w. A nice plasma effect is added when it locks to the DCF77 signal.

Please find the source code attached.
A video is available on YouTube: http://youtu.be/OYGP_k4zEm4

Have fun,
Markus

Nice. I like to look over your projects, as they usually have something of interest to me.
I recently bought some of these cheap 160x120 lcd's from ebay, have a fastraxx gps module (for time), so I may try this out.

(I also created your music box player, which worked pretty good- I could only get my pic32 to get to 60Mhz, so I had something like ~28 voices I could do)

Awesome. This is really interesting. But I was wonderng what kind of barcode reader can read such a
qr code? I have two QR Code readers in hand. Are the available to read?

This plasma effect is awesome! Maybe I use it for some other project. :)
