Must I specify SPI pins as hardwired pins numbers?
When I use a shift out operator, can I not use a variable to specify the pin number?
If not, why not? I always thought that naming pin numbers is good programming practice.
Re-inventing the wheel is not a waste of time if, when you are done, you understand why it is round.
