The VCard Editor

What is this?

The VCard from Watterott is a small LED matrix with 12x8 SMD soldered LEDs. The card has an Atmel ATmega328 microprocessor with 8Mhz clock frequency, and has the size of a business card. As you can see below, the card is very nice to send small messages, for example X-mas greetings.

HEX codes for frame


See below a small demo for XMas greetings. You must insert the frames into the VCard example sketch

This editor will be open-source in some days after xmas when I cleaned up the code. Leave me feedback for further ideas and issues already here.
