A CAN node is in error active state when both the receive and transmit error
counters are below 128.
Every CAN node keeps a count of how many receive and transmit errors
have occurred. The rules for how these counters are incremented and
decremented are defined by the CAN protocol specification.
A CAN node is in error passive state when one or both of its error counters
increment above 127. This state is a warning that a communication problem
exists, but the node is still participating in network traffic.
A 29-bit arbitration ID. Frames that use extended IDs are often referred to
as CAN 2.0 Part B (the specification that defines them).
Federal Communications Commission.
A unit of information transferred across a network from one node to
another; the protocol defines the meaning of the bit fields within a frame.
Also known as packet.
Hexadecimal.
Hertz.
An abstraction of a specific real-world thing; for example, Mike is an
instance of the class Human. Also known as object.
International Standards Organization.
Kilobytes of memory.
