I am also looking for a full datasheet.
google can easily track down one for you.
Looks to be fairly simple: parallel bus for data / commands, and a few other pins to work with.
Shouldn't be difficult to write a driver for it.
Hi,
I've dealt with a fair bit of noritake stuff, just send an email to the UK guys and they should be able to hook you up with a datasheet.
Not sure about libs, the interface is so straightforward I just write my own.
The distributor sent me a full datasheet. Unfortunately, an AVR library for this VFD is not available, because it was introduced in 1991.
There is still a problem with line breaking. I will try to fix it in future. Advices are welcomed!
Don't have any advice sorry, but looks beautiful!
So I made some progress. Here you have the source codes for inspiration. But my VFD named GU256X64-312 was designed in 1991, you will hardly buy it nowadays.
Now this library does not work with my GU256X64-312. I will try to fix it later...
That library has a far better code structure than yours.
If you are to make it work for your display, I would suggest that you follow that structure - the differences are likely in timing, or initialization.
The code, however, can be improved.
In vfd.c:
#include "uart.h"
Probably no reason to include it here.
uint8_t yoffset = _vfd_coord.y % 8;
Unless the compiler optimizes that, it can be sped up significantly.
You may want to look into a graphics library for Nokia 6110. The drawing routines there are really nice.
Here is my dot matrix display showing graphic features. Library was made by
Kim Boricha.And here is
Kim Boricha's original video:

I put some pictures on my GU256X64-312. I used The Dot Factory for converting *.bmp to data.
The Dot Factory is a small, GPL, open source tool intended to generate the required C language information to store many fonts and images, as efficiently as possible, on a microcontroller.

252×56 pixels, although the VFD has 256×64 pixels.
