Reading little-endian registers

Hardware register dumps and binary control protocols often store numeric values least-significant byte first. The u16_le dtype lets you decode and encode those values while keeping the bytes exactly as they arrived.

from tibs import Tibs


register_dump = bytes.fromhex("34 12 cd ab 2a 00")

device_id, status, sample_rate_hz = Tibs.from_bytes(register_dump).to_values("u16_le")

assert device_id == 0x1234
assert status == 0xabcd
assert sample_rate_hz == 42

updated = Tibs.from_values("u16_le", [device_id, status, 1000])

assert updated.hex == "3412cdabe803"

The important part is that the raw byte order stays visible in the example: 34 12 is still the stored data, while the decoded integer is 0x1234.
