How to Use BCH Code

Choose Text or Binary input; Text is the default.
In Text mode, each byte is split into two four-bit nibbles.
The encoder appends three parity bits to each nibble with generator polynomial 1011.
Use Decode to reconstruct paired codewords and report corrected single-bit errors.

The current implementation is a compact BCH(7,4) cyclic code. Each 4-bit block becomes a 7-bit codeword, and the decoder uses a syndrome lookup for one-bit correction.
