This won’t mean much to anyone but I have it (IVL2-7/5) working. Trying to understand Russian datasheets on the IVL2-7/5 VFD and piecing together bits of info from around the web and I have it working. It was like some sort of secret/puzzle that you had to pass to be accepted by other engineers. I have that same feeling I had with A Blinking Red LED. Yeah Baby!

  1. Looking forward to more detailed post. I also have a few of them lying around but I didn’t find the time to try them yet. Do you want to use yours with an ATmega?

    1. I used the MAX6920 VDF Display Driver. It worked really well. It has all the charge pumps built in, and all you have to is multiplex the channels for each digit.
