Getting the Sources

git clone http://www.0x53a.de/git/cube-3

Building the Bootloader

(Notice: You do not need this step if you have a preflashed cube, only if you want to modify the bootloader.)


You will need

  • gmake
  • avr-libc, avr-binutils, avr-gcc
  • avrdude
  • an ISP- or JTAG-Programmer like AVR ISP mkII, usbasp, or any (avrdude-compatible, if you want to use the Makefile) other.


The bootloader is in the directory bootloader/firmware/. It can be built with

cd cube-3/bootloader/firmware/


To flash it, modify the bootloader/firmware/Makefile:

AVRDUDE = avrdude -P usb -c avrispmkii -p m8 -p $(DEVICE)

to match your programmer. This is the line for AVR ISP mkII. If you have a programmer, you probably know how to do this, so I won't get into it.

Then apply fuse settings and flash:

make fuse
make flash

Building the Bootloader Application

The Windows app is already prebuilt in the git repository. The bootloader is bootloadHID, so please inform yourself about how to do this for Windows.

For Linux, the command line application is included in bootloader/commandline/


You will need libusb with headers.


cd cube-3/bootloader/commandline

Building the Standalone Firmware

The standalone firmware simply takes a sprite file and plays it repeatedly. It is included in src-standalone. The requirements are the same as for the Bootloader firmware.


cd cube-3/src-standalone


There are now several ways fo flash this device. Two are:

Flashing via ISP

First is using an ISP programmer. In this case you have to adapt the file src-standalone/programmer.mk:

PROGRAMMER = -c avrispmkII -P usb

These are the avrdude parameters you have to adapt to your ISP programmer.
