BlaeckSerial 6.0.0

Frames

B0 — Symbol List (0xB0)

Signal schema: names, types, master/slave config.

Element	Size	Type	Description
MasterSlaveConfig	1 byte	uint8	0x01 = master, 0x02 = slave
SlaveID	1 byte	uint8	0x00 for master; device-specific for slaves
SymbolName	variable	string	Signal name
DTYPE	1 byte	uint8	Datatype code (0x00–0x09). See Datatypes

D2 — Data (0xD2)

Signal values with SchemaHash, 8-byte Timestamp, StatusByte, StatusPayload, and CRC32.

Element	Size	Type	Description
RestartFlag	1 byte	uint8	0x00 = normal, 0x01 = first frame after restart
SchemaHash	2 bytes	uint16	CRC16-CCITT over signal schema. See Schema Hash
TimestampMode	1 byte	uint8	0 = none, 1 = micros, 2 = UNIX
Timestamp64	8 bytes	uint64	Conditional: only if TimestampMode > 0
SymbolID	2 bytes	uint16	Zero-based signal index (matches B0 order)
DATA	variable	raw bytes	Signal value, size per DTYPE
StatusByte	1 byte	uint8	Device/hub status. See Status Codes
StatusPayload	4 bytes	raw bytes	Status-specific data
CRC32	4 bytes	uint32	Integrity checksum. See CRC32

B3 — Devices (0xB3)

Device identity with LibName.

Element	Size	Type	Description
MasterSlaveConfig	1 byte	uint8	0x01 = master, 0x02 = slave
SlaveID	1 byte	uint8	0x00 for master; device-specific for slaves
DeviceName	variable	string	User-defined device name
HWVersion	variable	string	Hardware version
FWVersion	variable	string	Firmware version
LibVersion	variable	string	Library version (e.g., "6.0.0")
LibName	variable	string	Library name

C0 — Restart Notification (0xC0)

Notifies that a device restarted. Same layout as B3.

Element	Size	Type	Description
MasterSlaveConfig	1 byte	uint8	0x01 = master, 0x02 = slave
SlaveID	1 byte	uint8	0x00 for master; device-specific for slaves
DeviceName	variable	string	User-defined device name
HWVersion	variable	string	Hardware version
FWVersion	variable	string	Firmware version
LibVersion	variable	string	Library version (e.g., "6.0.0")
LibName	variable	string	Library name
