Hi - im a newbee to both electronics and Arduino and are haviong trouble with hooking up an VFD from Futuba.
I dont have the excact datasheet from Futuba, but on their site I found sheets from similar displays.
So - in my newbee enthusiasm, eagerness and NAIVETY I thought it was so simple as to connect the filament to grnd and pick the different grid/anode pairs to light up the different segments in the display.
In other words beeing able to program the segments on and off with a loop in Arduino, without a dedicated IC controller, by simply adressing the correct pin combinations and setting them "HIGH"
Test 1:
i connected the 4 filament pins to GND and different grid/anode pin pairs both to +5v simultaniosly.
Test 2:
i connected the 4 filament pins to GND and different grid/anode pin pairs to +5v and GND
Ive tested other posibilites also, but...
No reaction on the display!
The display was fully functional - at least before testing.
Co anyone have a clue to how to make a basic setup?
Finetuning led intensity etc is not important at this stage.... Im happy just beeing able to "see the light"
