Hi, I have a Adafruit 0,56" 4-didgit 7-segment display with I2C. I wired this just like on the schematic, but it's not working. I already tried changing the I2C address with the jumpers on the back without success. Anybody with the same display, or ideas how to get it working?

It looks like the Adafruit display is driven by a completely different chip (HT16K33 instead of the Sparkfun AtMega328), so you need to change the code to match the Adafruit one.

Ok thanks, I have no idea how to do that, so I guess I'll try to get the Sparkfun :)
