@pianofire That was fast ! The next step could be trickier ...

[faz808]

This could prove a major stumbling block - Error Correction Coding.

[pianofire]

@faz808 Well that was the easy bit!

[pianofire]

@faz808 Yes it looks fun! https://www.thonky.com/qr-code-tutorial/error-correction-coding I have some C# code that I might try to convert

[faz808]

I'll leave that bit with you then. My brain needs a rest - it's hurting...

[pianofire]

@faz808 OK will you look at encoding then?

[faz808]

I'll give it go.

[faz808]

Getting there - slowly...

@faz808 No rush. I am still keying in this monster! https://www.thonky.com/qr-code-tutorial/error-correction-table

[faz808]

What a team !

[pianofire]

Finished the table!

Just got to check I've got 104 bits in final code and tidy up my messy code!
Had to have "HELLO WORLD!" to avoid odd number of chars. Makes it a bit easier. Work on that part later..
If not 104 bits a bit of padding to do.

So far …

If you want to tidy up the mess feel free !!!
I'll do it, just wanted you to see progress.

@faz808 That's fine. No pressure, I still have plenty to do on the error correction anyway

[faz808]

I haven't checked for crashes with other phrases - I daren't !
There's bound to be run errors but if we can generate a QR code with HELLO WORLD! then that's got to be a major step forward...

@faz808 Yes that is my initial objective too! I should have some more time to spend on this over the weekend

[faz808]

Fingers crossed !

[pianofire]

@faz808 Oh Joy another massive table! https://www.thonky.com/qr-code-tutorial/character-capacities

[faz808]

Will it ever end !!!

[pianofire]

@faz808 A bit more progress on the error correction AYK73MBHMN

Can now determine the smallest version for the data ( up to about version 12 )
