I have a VFD (Noritake GU140x32f-7806) that's been gathering dust forever so I figured I might as well give it a try...
When I checked the datasheet it seemed easy enough, the dimensions and connection appear to be identical to the OLED Xavier is using for the new kits.
Except I had shortened the PCB for another project so I had to *ahem* improvise a bit...
The datasheet claims "LCD compatible" but of course it didn't work
After hacking some timings in the firmware - I guess the LCD/OLED are more tolerant? - it seems to work. The photo isn't great, it looks much better live.
Not sure whether to keep it...
- It does have a bit of noise (high-pitched) but that might be inaudible in a case...
- The top of the display is almost flush with the buttons and ideally, there'd be a color filter or protection, so that might be more involved
- It might be the improvised connection, but I think it flickers occasionally. Or it's just using 10x as much power
- But it's graphics capable so that could be fun (although a lot of work)
