Noritake GU7000 Vacuum Fluorescent Display (VFD) Library

Noritake provides Arduino libraries for their displays; however, their Terms of Use do not allow re-publishing their Arduino libraries.

To download and install the library, follow the instructions on Noritake's website.

I have been using the GU7000 library with the GU144x16D-7053B display. Libraries for other Noritake displays are available at the above link.

Using the GU7000 Module

The GU7000 is a 5V device and requires 5V logic levels (Vcc * 0.8)

I measured supply current of up to 230 mA when the module was powered and most pixels were active, down to 200 mA with a blank screen. The module has a low power mode which draws about 40 mA.

Pin Functions (CN1):

1. VCC
2. SIN
3. GND
4. SBUSY
5. SCK (Synchronous Serial and SPI modes) or NC (Async Serial mode)
6. /RESET
7. SPI /CS (NC for other modes)
