How do diffraction and uncertainty relate to each other?

[cmcraes]

I couldn't find this else where so i figured id ask it here.
What is the relationship/difference between the two? To me diffraction just seems like a generalized and/or classical way to describe Heisenbergs Uncertainty principle.

So question: Are the two phenomena the same thing?

It is possible for things to be related without being the same.
HUP is a statement about measurement statistics in general while diffraction is an emergent phenomenon.
To see the difference, derive the 2-slit diffraction pattern from HUP.
