I have an IEE VFD (device # ASSY05464ASSY35119) that many years ago I had interfaced it with an Arduino Uno. It sat in my closet for years until I decided to clean out my closet. I found the display and before I canned it, I thought I would try to make it work. Unfortunately, after many days searching my hard drives for a sketch I used, it is no where to be found. So… here I am. Looking for anyone who might have a similar display. It is a 2x20 dot matrix display. It is a 5V device with a SERIAL interface and a 20pin IDC male connector. I’ve attached a datasheet for a VFD that is very similar to this unit although not from the device mfg: IEE (Industrial Electronics Engineers). I’ve contacted them for a datasheet and when I told them it was for a hobby project, they dropped me like a hot potato. I’ve connected it to an UNO R3 and used the SoftwareSerial library and defined pins 4 and 5 as the rcv and xmt pins (xmt connected to the SERIAL IN pin) on the interface connector. Other pins on the interface are RESET, CHIP SELECT, Addr0, WRITE to send commands to it. Nothing seems to work. I’ve tried sending simple single character commands to RESET, or CLEAR… nothing.
So, this is a long shot to see if any Arduino users have experience with this display before I send it to the garbage can.
