QR-Code Generator

Basic Implementation of QRCode Spec to ISO 18004:2015, with the limitations listed in Unsupported Features.

Versions 1H and 4H have been tested. Any other version who knows.. (Very likely there are typos in the version_data table. It was manually trascribed)

Unsupported Features

Micro Codes
Kanji
ECI
Reflectance Reversal
Mirror Orientation
C, K, R table-data is not populated on version 31-40; they wont work until it is filled
Decoding

Reed-Solomon Encoding

This is a very basic implementation, and I'd say a low performance implementation.

Useful Utilities

QRazyBox - a nice tool for decoding a qr-code and seeing what it thinks the data is. Used extensively to compare against produced qrcodes to help zero-in on implementation errors.

Thonky QRCode Tutorial - Excellent resource to supplement the ISO, which is not great at explaining itself.
