I have just got a vfd vu-meter. I have searched the internet about these items and I am getting the general idea of how to connect them. It looks not very easy, as there are several connections (grid, anode, filament) and it may require some kind of multiplexing to activate them. I see that there are several ic's related to vfd driving. Maybe, someone has already done this, or perhaps someone knows how to make them work. Any suggestions? Thank you in advance.
