I bought some Lite-On led displays with integrated shift register driver a few years back. They’re kinda cool, reducing the microcontroller pin count needed to drive two digits of alphanumeric displays to a mere three — chip select/enable, clock, data in. Not bad at all, even if they don’t have serial out like a proper shift register; the last cell of the shift register is connected to output latch to remove the need to externally fire the latch.
But good luck reading that datasheet.
So far so good, right?
aargh.
AAAUGH. WHY?! WHHHHYYYYY??!!! All this is missing is a liberal use of Comic Sans.
Please, do not do this.
