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

QR Code version 11
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.

Re: QR Code version 1
ZX Spectrum sample code added! The code is capable of plotting the barcode using 1x1, 2x2, and 4x4 square pixels per module, selectable in compile time. The encoder and plotter code is shared between the ZX81 and ZX Spectrum versions, only the pixel routines are specific to each of the platforms. ht...

Re: QR Code version 1
Then you could make a bigger version for ZX81 as well as is supports a resolution of 256x192 pixels. With HRG driver like used by Z88dk. In general the ZX printer is able to print high resolution graphics as well, maybe a special driver is needed. My goal for now is to show them on the screen. As f...

Re: QR Code version 1
QRCODE.P Not sure what you're trying to do, the machine code cannot be relocated as it uses some absolute addresses, but you've added a line before the QR Code routines that live in line 10: 0 REM #5 ?)# U#RND RETURN #C- RETURN #C) RETURN #C� RETURN #ASN aINKEY$ RETURN #ASN PAUSE INKEY$/#;;;63INKEY...

QR Code version 1
Hi All, I've written a QR Code version 1 generator in Z80 assembly, along with a plotter for the ZX81: https://github.com/leiradel/qrc1 QR Code version 1 can encode 14 bytes of information. There's a PR which I'm changing a bit with a version 11 generator, capable of encoding messages with up to 251...
