Usage Example

The usage of the library is pretty straightforward, after the initialization, there are two methods: one to encode a list of bytes, and other to decode a packet. Below there is a basic usage example:

from pyngham import PyNGHam

pngh = PyNGHam()

data = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

pkt = pngh.encode(data)

print("Encoded packet:", pkt)

pl, errors, errors_pos = pngh.decode(pkt)

print("Decoded data:", pl)
print("Number of errors:", errors)
print("Errors positions:", errors_pos)
