aim_map.h
Maps a target's image position to turret angles (pure C++20, natively tested).

aiming::serialize
Blob serialize(const AimMap &map)
Packs a map into the 28-byte versioned layout, with the CRC-32 in the last four bytes.
Definition calibration_blob.cpp:32

aiming::deserialize
std::optional< AimMap > deserialize(std::span< const uint8_t > blob)
Parses a blob; empty if the length, magic, version, CRC or float values are invalid.
Definition calibration_blob.cpp:45

crc32.h
Shared CRC-32 for versioned NVS blobs (pure C++20, natively tested).

checksum::crc32
uint32_t crc32(std::span< const uint8_t > data)
CRC-32 (IEEE 802.3, reflected, init 0xFFFFFFFF, final xor 0xFFFFFFFF).
