ECU MC toolkit comprises two communication protocols: CAN Calibration Protocol (CCP) and Universal Calibration Protocol (xCP). CCP is an older protocol and works over CAN, while XCP, an expansion of CCP, works over several different physical layers. The ECU MC toolkit supports XCP over CAN, TCP/IP, and UDP.
The Automotive Diagnostic Command Set (ADCS) is an API that adds support for several automotive communication protocols: KWP2000 (Key Word Protocol), UDS (Unified Diagnostic Services), and OBD (On-Board Diagnostics). These protocols are used to communicate with an ECU to collect data and program onboard memory. They are often used for diagnostic purposes: gathering fault codes and monitoring the condition or status of the ECU during operation.
