For those who love the blue glow, this 128x64 bit resolution graphical VFD offers a striking high - brightness and high - contrast appearance. It's perfect for projects where clear reading is essential. You can easily read it in daylight and from any angle. The VFD module supports both 8 - bit parallel and SPI communication modes. With the SPI protocol, you can write and read pixels without needing a RAM buffer (unlike most 128x64 SPI displays that require a 1K RAM buffer). It runs on 5V and draws up to 500mA of current. There's a VFD driver and a 60V boost circuit on the back. You can use 3.3V logic for communication as long as it's powered by 5V. We provide a detailed tutorial and example code in the form of an Arduino library for text, bitmaps, and graphics. You can download the VFD graphic display Arduino library from GitHub, which includes example code for printing text, bitmaps, pixels, rectangles, circles, and lines. The code is easy to adapt to other microcontrollers.
Using this VFD is straightforward. First, make sure to power it with 5V. You can use 3.3V logic for communication, but always keep the 5V power supply. When connecting, choose either the 8 - bit parallel or SPI communication mode according to your needs. The SPI mode is great as it doesn't need a RAM buffer. To start creating visuals, download the Arduino library from GitHub. The library has example code that can help you print text, draw bitmaps, and create various shapes like rectangles, circles, and lines. It's easy to adapt this code for other microcontrollers too. Remember, this VFD draws up to 500mA of current, so use a suitable power source. When it comes to maintenance, keep it in a clean and dry environment. Avoid exposing it to extreme temperatures or humidity. If there are any issues, refer to the detailed tutorial that comes with the library.
