Wiring is fairly simple for the display. On the back is a 20 pin connector (2x10) that is used for all power and data. We supply an IDC cable to make wiring even easier. Note which way the red wire goes, it should be next to the little arrow on pin #1

For our tutorial, we'll be using the SPI interface. You can refer to the App Note for the pinouts in Table 17. Plug in wires into the following VFD connector pins:

  • Pin #8 - MISO (orange)
  • Pin #11 - SPI clock (yellow)
  • Pin #12 - MOSI (green)
  • Pin #13 - Chip Select (blue)
  • Pin #14 - Command/Data (violet)
  • Pin #9, #18, #19, #20 - Ground (black and brown)
  • Pin #15, #16, #17 - +5V (red)

Note that we skip #1-7, and 10.

Then you can connect these lines to the Arduino:

  • Orange (MISO) to Digital #12
  • Yellow (SPI Clock) to Digital #13
  • Green (MOSI) to Digital #11
  • Blue (CS) to Digital #10
  • Violet (C/D) to Digital #9
  • All black grounds connect together to GND
  • All red +5V connect together to +5V

These pin definitions can be changed to anything, but for now let's just use what's in the tutorial as shown. Later on, if you want to change the pins, you can set them in the top of the example file.

I also added a 100uF capacitor between +5V and GND in the image above but you may not need it
