6502-QR-code-generator

A simple DASM assembler library for creating small QR codes

Introduction

This project provides a simple QR code generator for the 650x family.

Note: The code is mostly specifically taylored for the Atari 2600 and a version 2 QR code. Other platforms or QR code versions have not been tested. But it should be adaptable without too major problems.

Features

  • easy to use DASM macros
  • assembler switches to taylor generator to your needs
  • code size optimized for minimal RAM and ROM space
  • all eight mask pattern supported
  • Atari 2600 demo code
  • generator code for Reed-Solomon ECC generator polygons accompanied

Limitations

  • only small, single block QR codes supported
  • only byte mode supported
  • no automatic mask pattern evaluation
  • tested only for version 2 QR codes (25x25)
