NEW PRODUCT – 128×64 Graphic VFD (Vacuum Fluorescent Display) – SPI interface. For blue-glow lovers, this is a graphical VFD with 128×64 bit resolution and a stunning high-brightness/high-contrast look. This module would be a great addition to any project where readability is a must – you can read it in daylight, and at any angle.
The VFD module supports both 8-bit parallel and SPI modes of communication. The SPI protocol allows to write and read pixels so no RAM is required to buffer the display (most 128×64 SPI displays require a full 1K RAM buffer since you cannot read from the display memory). The module requires 5V, and does draw quite a bit of current, up to 500mA. There is a VFD driver and 60V boost circuit on the back. You can probably use 3.3V logic to communicate with the module, as long as it is powered with 5V
You can download our VFD graphic display Arduino library from github which comes with example code. The library can print text, bitmaps, pixels, rectangles, circles and lines. The code is simple to adapt to any other microcontroller.
