Lithuanian airports disposed of some equipment, and there were devices with VFD screens (the devices themselves were specific, with very strange software). At least I got the VFD screens: Noritake Itron GU112x16G-7806A V3. I think the software is suitable for the whole family, so I wrote GU140x16G in the title because I wrote it based on that datasheet. The VFD module itself is probably fully compatible with the LCD module, but additionally has graphic module modes. Therefore, any software (and hardware) that supports a standard LCD module with a 14-pin connector works perfectly with the VFD module. There is a small issue that the module initializes a bit slower, but most of the software works.
However, compatibility wasn’t great for me, but I liked the large (and small) font, drawing, bitmap sprites, inversion, and so on.
The software for the AVR family microcontroller (fully compatible with my ARM library) is written as a “wrapper” for the standard LCD module. You only need to add additional commands to the existing LCD module software, and you already have a luminescent graphic display.
The VFD module itself also supports serial (ala RS232) and seems to have I2C and SPI control modes. You just need to solder the appropriate jumpers.
