Generating a QR code with only ARM Assembly

When generating a QR code, you can decide how much redundancy to include, making the QR larger for the same data but more resilient to "scratches".

Thanks. Looking into it [0], the QR code I'm testing uses the "up to 7% damage" error correction level L, which makes sense since there's already a lot of data being packed in the (vax proof) code.

... I still want to find a debugging/verbose QR decoder :-)
