Struct Tpx3Packet 

pub struct Tpx3Packet(/* private fields */);

TPX3 packet wrapper providing efficient field extraction.

Packet format (64-bit):

• Hit packets (ID 0xB*):

  • Bits 0-15: SPIDR time
  • Bits 16-19: Fine ToA (4-bit)
  • Bits 20-29: ToT (10-bit)
  • Bits 30-43: ToA (14-bit)
  • Bits 44-59: Pixel address (16-bit)
  • Bits 60-63: Packet type ID

• TDC packets (ID 0x6F):

  • Bits 12-41: 30-bit TDC timestamp
  • Bits 56-63: Packet type ID

Implementations

impl Tpx3Packet

pub const TPX3_HEADER_MAGIC: u64 = 0x3358_5054

TPX3 header magic number (“TPX3” in little-endian).

pub const fn new(raw: u64) -> Self

Create from raw 64-bit value.

pub const fn raw(&self) -> u64

Get raw packet value.

pub const fn is_header(&self) -> bool

Check if this is a TPX3 header packet.

pub const fn is_tdc(&self) -> bool

Check if this is a TDC packet (ID 0x6F).

pub const fn is_hit(&self) -> bool

Check if this is a hit packet (ID 0xB*).

pub const fn packet_type(&self) -> u8

Get packet type identifier.

pub const fn chip_id(&self) -> u8

Get chip ID from header packet (bits 32-39).

pub const fn pixel_address(&self) -> u16

Get 16-bit pixel address from hit packet.

pub const fn toa(&self) -> u16

Get 14-bit Time of Arrival.

pub const fn tot(&self) -> u16

Get 10-bit Time over Threshold.

pub const fn fine_toa(&self) -> u8

Get 4-bit fine ToA.

pub const fn spidr_time(&self) -> u16

Get SPIDR time (16-bit).

pub const fn tdc_timestamp(&self) -> u32

Get 30-bit TDC timestamp from TDC packet.

pub const fn pixel_coordinates(&self) -> (u16, u16)

Decode pixel address to local (x, y) coordinates.

• dcol = (addr >> 8) & 0xFE
• spix = (addr >> 1) & 0xFC
• pix = addr & 0x7
• x = dcol + (pix >> 2)
• y = spix + (pix & 0x3)

impl Tpx3Packet

pub fn from_bytes(bytes: [u8; 8]) -> Self

Create from 8-byte array (little-endian).

pub const fn is_pixel_data(&self) -> bool

Alias for is_hit - checks if this is pixel data.

pub fn timestamp_coarse(&self) -> u32

Calculate coarse timestamp in 25ns units from SPIDR time and ToA.

Formula: (spidr_time << 14) | toa Matches C++ reference implementation.
