When designing any microcontroller (uC) based system, I find it can be a good idea to first plan out what signals are going to go to which pin on a the uC. Sitting down and filling out a document like the one pictured above can be a very efficient way to organize your thoughts and rap your head around your design. Your allocation document will also help when routing your schematic, PCB, when you are writing software, and when you are debugging. This document can be very valuable and is often overlooked!
