# WarpPI Calculator

## Step-by-step algebra calculator for Raspberry PI

**This project is experimental and strictly related to my calculator, designed to run on a raspberry PI Zero.**\
**Many fundamental features are missing, this project is still in its infancy.**

If you really want to build and test it on your computer take account of that.

## Github

This project is hosted on [Github](https://github.com/Cavallium/WarpPI).

## Live preview

The live preview has been built using TeaVM: a JVM made in javascript.
Obviously it runs slower than the original software and it can have some issues.

## Keypad PCB

The schematics are available on [Circuitmaker](https://workspace.circuitmaker.com/Projects/Details/Andrea-Cavalli/Scientific-calculator-Keypad).
