Hello All,


I have got a new GU140X32F - 7003 VFD, I connected a VCC and ground to its pin 2 and 1 (parallel interface). But i dont see anything, should I expect any illumination just by giving the power supply.
If yes the what might have gone wrong or if no then what should I do further ?

I am going to interface it with a 8 bit MCU with a parallel interface. How should I begin ?

Plz guide.
