I'm building a clock with a russian IV-18 VFD tube and a MAX6921 as it's driver.
Is there a library or software method to control a MAX6921 VFD driver chip?
According to the datasheet, the IC uses an "industry standard 4-wire interface". However, googling around I can't seem to find any arduino library that might work this way.
Is there anything already "in the wild" or would I have to write my own library to drive this IC? I'm really new to arduino and this is my first real project beside the blink-a-led examples.
Thanks in advance!
