Includes a short Python script which uses [asciiqr.com](http://asciiqr.com/) to convert text strings or existing QR codes into code page 437 (or UTF-8) strings or hex values.\n\n### What is this written in?\n\nAssembly (NASM) and Python.\n\n### What's the point?\n\nNone, really. Reawakening the basic knowledge of assembly laying dormant somewhere in my brain for eons.\n\n### How do I use this?\n\n1. Replace `qr_string db` with your own QR code using ascii.py (optional),\n2. Compile using NASM (or whatever works, I suppose),\n3. Use it as the boot sector on a CD, USB drive, SD card, floppy disk, etc.\n4. Boot from said media,\n5. Scan QR code (optional).\n\n---\n\n### Full output of python ascii.py -h:\n\n```\nusage: ascii.py [-h] [--hex] [-n] [-o FILE] [-s] [--skip-cr] [-u] [--utf8] input\n\nconvert qr codes into codepage 437 ascii - uses asciiqr.com\n\npositional arguments:\n  input                string to be converted into an ascii qr code\n\noptional arguments:\n  -h, --help           show this help message and exit\n  --hex                print output as hex values\n  -n, --nasm           print output as a nasm-ready string of hex values\n  -o FILE, --out FILE  print output to specified file\n  -s, --strip          remove newlines\n  --skip-cr            do not add carriage return (when -s is not used)\n  -u, --url            treat input as a url to an existing qr code\n  --utf8               convert to utf-8 instead of codepage 437\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F54ac%2Fqr-bootloader","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F54ac%2Fqr-bootloader","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F54ac%2Fqr-bootloader/lists"}
