ra8_epd_cal_record_t Struct Reference

Decoded per-device calibration record. More...

#include <ra8_epd_cal.h>

Data Fields
uint16_t	vcom_mv
	VCOM magnitude in millivolts (e.g.
uint8_t	schema_version
	Schema the record was written under.

Detailed Description

Decoded per-device calibration record.

The in-memory form of the serialised blob. schema_version is carried through so a caller can tell a freshly written record from one migrated off an older schema.

Invariant

vcom_mv is the panel's VCOM magnitude in millivolts (VCOM itself is negative; the sign is implicit).

schema_version <= k_ra8_epd_cal_schema_version.

Example:

ra8_epd_cal_record_t rec = {.vcom_mv = 1530U,
                            .schema_version = k_ra8_epd_cal_schema_version};
