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 -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
