Hi All,
I've merged a PR that implements QR Code version 11 in Z80 assembly, along with a plotter for the ZX Spectrum. QR Code version 11 can encode 251 bytes of information.

QR Code version 11
Re: QR Code version 11
And now Code 2 of 5, which takes much less code to implement and can represent 16 digits using 2x2 pixels on a Speccy.
