You might want to look at the "i2500vfd" driver in LCDproc.
Some features which might be relevant, performance wise:
- 140x32 pixels resolution
- 27 fps (with hardware double buffering)
- B/W with two additional gray scale colors
- No MPSSE mode or anything, uses a micro controller to receive the data
and drive the display (we drive the VFD tube directly).
The trick for decent performance was to use a packed pixel format.
IIRC we also don't use the full 8 bits of the FT245BM chip, two or so
are reserved for in-field/remote flashing of the Atmel micro controller.
That display is also the reason we developed libftdi in the first place :)
Cheers,
Thomas
