This is a fast implementation of a truncateable extended (127,120) Hamming code.
It features an encoder and decoder that allow for any number of bytes to be transferred. If the amount of data that needs to be transferred is too large for one block it is automatically broken up into chunks of 15 bytes with the last block having all the "undefined" bits past the end silently skipped.
The encoding is performed as a separateable code by appending the redundancy information at the end of each block. All coding assumes overall even parity.
The library is mostly targeted towards STM32 microcontrollers, but should be portable enough to run on essentially everything with enough RAM to hold the encode and decode buffers.
This library was inspired by the explanations presented by @3blue1brown in the following Youtube videos:
