A tiny ( < 200 LOC ) QR code generator

## BUILD

`make qr`

## USAGE

```

./qr yne.fr/qr

```

## PREVIEW (debug mode)

![preview](img/preview.gif)

## LIMITATIONS

- `BYTE:4` encoding only (no `NUM:1`, `ALNUM:2`, `KANJI:8`)

- Data padding is made of `0` but shall use `236` and `17`

- QR v2+ won't work yet (due to ECC ?)
