Hi to all, here's hoping the new year is going to be a good one.
Can anyone suggest a way of driving a VFD display from a PIC?
The VFD is a custom one from a broken DVD player and still works fine.
The problem is that besides the 3v filament supply it needs about 12 to 14v for the grids.
Other than using ULN2803 or 4 darlington driver arrays is there another way to switch the voltage to the grid that lights the segments? I would really like to use this display for a project especially since I spent hours finding the pin configurations pin by pin!![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
