I picked up one of those (the blue ones) and i'm looking for a driver for it. I can't seem to find any decent digit multiplexing ICs for a CA display.
SAA1064 does pretty much everything I want it to (I2C, self multiplexing, small programing footprint, little processor overhead) but I don't figure I can get it working with that display (at least not for 4 unique digits).
I don't want to go with a BCD unless it'll output Hex as well (can't remember the proper name for them).
I figured out a decient solution using 4x 8 bit shift registers, a 4 bit (or and multiple of 4) an 8 channel mux, a few transistors and an oscillator.
Thus far, octopart has failed me in my search for a 7-segment 4 digit(+) driver w/ CA. Can I just use a chip made for CC and use some transistors?
