 I built this macro keyboard because I was spending way too much time with

 I decided to implement an OLED display that's compact and instead of a diode-resistor
 configuration I've decided to go with a shift register instead, simply because
 the complexity of the PCB is brought way down with fewer components to fail
 and its a lot easier to replace a socketed dip-16 IC than it is to desolder
-a diode and the number of pins I save using a shift register allows for future
