So my MCU teacher said I should use a long ass ternary to determine which pins should be set high for a given number on a seven segment display. Cause the display was on a single 8-bit port on the mcu I decided to generate a bitmask with a switch statement and set the port directly.

    His argument was, that if the pins change to a differen or multiple ports I would need to change more code. Yeah, but its a good idea to design the hardware to use a single port. And with good documentation the changes can be made easily.

    You're right of course, that's how you do it. If the HW designer puts such correlated pins on different ports, he needs a smack in his face.
