autosar-e2e¶
Description¶
This library provides fast C implementations of the E2E CRC algorithms and E2E profiles.
Installation¶
You can install autosar-e2e from PyPI:
python -m pip install autosar-e2e
Usage¶
CRC example¶
import e2e
crc: int = e2e.crc.calculate_crc8_h2f(b"\x00\x00\x00\x00")
E2E P02 example¶
import e2e
# create data
data = bytearray(b"\x00" * 8)
data_id_list = b"\x00" * 16
# increment counter and calculate CRC inplace
e2e.p02.e2e_p02_protect(data, data_id_list, increment_counter=True)
# check CRC
crc_correct: bool = e2e.p02.e2e_p02_check(data, data_id_list)
Test¶
