Adafruit RPN calculator tutorial

[mpark]

This might be of interest to calculator builders.

I just noticed that Adafruit* now carries the 400x240 pixel Sharp Memory LCD (as used in the SwissMicros DM42 and DM41X) and they've published plans for an RPN desktop calculator using that display: https://learn.adafruit.com/diy-rpn-deskt...cuitpython

The calculator software is written in CircuitPython, Adafruit's dialect of Python3, and uses a decimal arithmetic library. Pretty neat!
