    Some people use them to drive 7-segment LEDs. They don't have digit control, only segment control, so you need one per digit.




    It turns out my supplier for 7-segment LEDs also print and assembles PCBs. It wouldn't be cost effective to ship my LEDs back, so I might very well do the jump to the MAX7219 if I have to buy more LEDs.

    I'm keeping all my options open for the time being, but the MAX7219 does offer one really neat feature; an intensity control. That TPIC6B595 is a close 2nd for common anode LEDs.

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
