# 6502-QR-code-generator A simple and free 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 (see instructions.txt). If you make use of my code or have questions, please let me know. ## Features - easy to use DASM macros - assembler switches to taylor generator to your needs - code optimized for minimal RAM and ROM space - all eight mask pattern supported - Atari 2600 demo code (randomly generates some Atari 2600 related messages) - generator code for Reed-Solomon ECC generator polygons accompanied (can also be integrated to compute on-the-fly) ## Limitations - only small (versions 1, 2 and 3), single block QR codes supported - only byte mode supported - no automatic mask pattern evaluation - tested only for version 2 QR codes (25x25) - memory organization has to be implemented platform specific
