K-Line Protocol Stack
ISO 9141 and ISO 14230 (KWP2000) enable bidirectional serial communication over a single wire known as the K-line. Together, they form the K-line protocol. iWave’s K-line protocol stack supports automatic detection of the internal protocol and communicates accordingly, allowing developers to focus on application-level development. The stack is fully compliant with both ISO 9141 and ISO 14230 standards.
