Encode algorithm QR-code

Question

Who knows how to generate qr-code? And how to decorate like here http://mojiq.kazina.com/?

Answer 1

Most of the time, the problem is the Finite-Field arithmetic, because it is a little bit different. And once you have the generator working, the error-correction techniques make it harder to see if the code is generated correctly. There is another site which has ECC generator: http://www.pclviewer.com/rs2/calculator.html But note that this generator also does not work correctly in all cases, same as Thonky's error code correction generator.

A small project I made allows step-by-step debugging and following the creation of the QRCode and manually changing all the parameters - something no generator on web does. The link: https://github.com/Legoless/QRCode
