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.

faz808

So far …

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

pianofire

@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...

pianofire

@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 )

faz808

Glad I didn't volunteer to enter that lot..
Well done !

pianofire

I have found some more tables but I think by entering these I won't have to try to understand the maths so I don't mind keying them!

pianofire

@faz808 Now have ploynomial division working with no clue what it does!

faz808

I thought everyone knew what Polynomial long division is . .ho ho ho ...
Polynomial long division is an algorithm that implements the Euclidean division of polynomials, which starting from two polynomials A (the dividend) and B (the divisor) produces, if B is not zero, a quotient Q and a remainder R such that. A = BQ + R, and either R = 0 or the degree of R is lower than the degree of B.
Don't understand a word of it but well done sir.
What the difference between ploynomial division and Polynomial long division?

faz808

Seriously, how are we doing?

pianofire

Well this is the next bit https://www.thonky.com/qr-code-tutorial/structure-final-message

pianofire

But for our short message we could skip straight to here: https://www.thonky.com/qr-code-tutorial/module-placement-matrix

faz808

At least it doesn't look like there's any maths involved. Just bit placement.
