A complete avrdude call could be e.g.:
avrdude -p attiny2313 -c avrisp2 -P COM6 -B 10 -U lfuse:w:0xe4:m -U flash:w:winkdings_herz.hex
On MacOSX the call looks like this:
avrdude -p attiny2313 -c avrisp2 -P usb -B 100 -U lfuse:w:0xe4:m -U flash:w:winkdings_herz.hex
Standard Heart Firmware
Note: The Vcc pin of the ISP connector is not connected. This was done to prevent LEDs to get a too high voltage when the Winkdings is programmed with a progammer using 5V. Therefore the Winkdings needs to be switched on, so it gets power.
Unfortunately this causes problems with some programmers, e.g. the AVRISP mkII, which probes the Vcc pin and rejects programming if there is no voltage. As a workaround you can temporarily connect 3V+ with the Vcc pin.
