Is there a way to make a cathode driven driver for LED segments, operate an anode driven set of LED segments? (whooo whoo!!) I would like to say no... and go another direction, honest!
How about an np|pn junction? I have heard something about these, but never considered it an advanced state of idiocy.
now if I put the cathode driver, behind the LED segments,
that is to say, put the cathode of the 4 digit array to the driver chip, and then fire individual grounds to each of the anodes on the segments --- hold it LED's are diodes and can't run backwards. so scratch that one... how about the chip? is it a diode or can I connect it up backwards driving all 4 with a common cathode follower that swaps the PN?
