* driving a boost-converter to generate 30V
* generating the AC for the filament
* driving 4 8-bit-shift-registers that in turn address 4 8-bit-CMOS-drivers (powered by the 30V)
The AC-part is still a little bit ugly (using TIP41/TIP42 transistors instead of MOSFETs), but I can already display things!
My mega-project is a generic driver for VFDs.
The ATmega I use is
