Bar code detection is provided by zbar. It's in there too.

Lib zxing is written is Java and not in C so we can't use it.

Um, anyway, check the blog out for a post about what have have onboard. We basically have everything other than Aztec codes and PDF417.

If you want faster processing we'll have that this year with the STM32H7. It will double the performance to be on par with the Raspberry PI zero.
