Module calib_store 

Calibration EEPROM serialization.

Structs

CalibEntry

Per-key full-travel calibration value stored in EEPROM.

Constants

CALIB_BUF_LEN

Pre-computed buffer length for the HE matrix.

CRC16 🔒

CRC-16/CCITT-FALSE (poly 0x1021, init 0xFFFF).

CRC_LEN 🔒

Byte length of the trailing CRC field.

EEPROM_BASE_ADDR

EEPROM word address at which the calibration block begins.

ENTRY_LEN 🔒

Byte length of a single serialized entry (one u16 full-travel value).

HEADER_LEN 🔒

Byte length of the header: magic + version.

MAGIC 🔒

Magic number identifying a valid Q6 HE calibration block.

VERSION 🔒

Format version. Must be incremented on any incompatible layout change.

Functions

read_array 🔒

Copy exactly N bytes from buf[start..end] into a fixed-size array.

serialize

Serialize entries (row-major, ROW × COL) into buf.

total_len

Compute the total serialized byte length for a rows × cols matrix.

try_deserialize

Attempt to deserialize a calibration block from buf into out.
