hi... thanks for this excelent hash... these are the links for my arduino port (attempt :)

in first instance i tried to port it using Daniel Kirchner's C++ constexpr library, it worked but he suggest me to better use the original xxhash.h file from this project and gave me some advices on how to do it, it worked better.... this is the same message i sent him that i think also applies to you...

i was looking for a light and fast hash function for arduino, also present in php to make interact them

i checked crc16 (native in avr-libc) but it is not so 'entropic'
i know there are md5, sha1 and other hash libs for arduino but they are huuuge
another candidate i saw were djb2 hash, but until simpler is slow and has no native php support
others i saw were Paul Hsieh's SuperFastHash and Eric Ztamnl Fast-Hash, but have larger code and no port to other langs

until maybe not perfect i think this lib is the best option we have (short code, efficient, ported), i think this libs would be very useful for all arduino projects, i hope you don't mind if i (try to) port this lib to arduino
