CAN identifiers of either standard (11 Bit) or extended frame format (29 Bit) size

type t

A CAN identifier of up to 29 bit; it includes the property of it either being a CAN 2.0A (sff, 11 Bit) or CAN 2.0B (eff, 29 Bit) identifier.

val create_sff : int -> t

Create a valid CAN 2.0A standard frame format identifier with 11 bit from an integer value. Masks all bits that are not in sff_mask.

val create_eff : int -> t

Create a valid CAN 2.0B extended frame format identifier with 29 bit from an integer value. Masks all bits that are not in eff_mask.

val to_int : t -> int

Get the 11 bit (sff) or 29 bit (eff) CAN identifier as integer.

val make_sff : t -> t

make_sff id transforms a CAN id making it a standard frame format identifier. If id already is a CAN2.0A identifier, this is a no-op.

val is_sff : t -> bool

is_sff id returns whether the id id is a standard frame format identifier.

val make_eff : t -> t

make_eff id transforms a CAN id making it an extended frame format identifier. If id already is a CAN2.0B identifier, this is a no-op.

val is_eff : t -> bool

is_eff id returns whether the id id is an extended frame format identifier. This is the negation of is_sff: is_eff x = not is_sff x.
