1、XCP协议简介 XCP全称Universal Calibration Protocol，是由ASAM (Association for Standardization of Automation and Measuring Systems,简称 ASAM)组织在2003年提出的可在不同的通信总线上进行标定的新型标定协议，这里的X代表不同的传输层上传输(CAN、Ethernet、FlexRay、SCI、SPI、USB)。XCP的应用场景：上传ECU数据，实现对ECU内部 calibration source can be performed. Only a complete calibration will restore the Protocol to an optimum performance level. For proper calibration instructions refer to the calibration section of this manual. Instructions o Select the Diagnose mode by pressing the DIAG key. o Press the ò (down arrow) key until RCVR SEN is displayed. The ECU Measurement and Calibration Toolkit provides high-level, easy-to-use functions based on the CAN Calibration Protocol (CCP) that ECU designers, testers, and engineers can use to build their own customized measurement and calibration applications. The mark LabWindows is used under a license from Microsoft Corporation. This CAN Specification consists of two parts, with • Part A describing the CAN message format as it is defined in CAN Specification 1.2; • Part B describing both standard and extended message formats. In order to be compatible with this CAN Specification 2.0 it is required that a CAN implementation be compatible with either Part A or Part B The XCP Reference Book. The reference book "XCP - The Standard Protocol for the Embedded Development" describes the fundamentals and the application areas of the XCP measurement and calibration protocol. The authors describe: Fundamentals of the XCP protocol. Setting up and creating an ECU description file A2L. Different calibration concepts. CCP and XCP, or the CAN calibration protocol and the universal measurement and calibration. protocol, as defined by the Association for Standardization of Automation and Measuring Systems (ASAM), were designed for calibration and data acquisition on CAN from the ECUs. These are generally used in automotive vehicles for run-time automation testing. XCP (protocol) XCP (or) "Universal Measurement and Calibration Protocol" is a network protocol originating from ASAM for connecting calibration systems to electronic control units, ECUs. It enables read and write access to variables and memory contents of microcontroller systems at runtime. Entire datasets can be acquired or stimulated synchronous CAN ISO-TP - Transport Protocol (ISO 15765-2) When implementing diagnostics on CAN, one challenge is the size of the CAN frame payload: For Classical CAN frames, this is limited to 8 bytes and for CAN FD the payload is limited to 64 bytes. Vehicle diagnostics often involves communication of far larger payloads. Types of CAN Communication Protocol. There are four main types of CAN with respect to speed, wire and software, High Speed CAN: It is type of CAN which has transmission rate up to 1 M bits. Low Speed/Fault Tolerant CAN: It is the type of CAN which has transmission rate up to125 K bauds. It is basically the small satellite which triggered the Das CAN Calibration Protocol (CCP) ist ein auf CAN basierendes Netzwerkprotokoll. Das englische Wort Calibration bezeichnet die Bedatung (Applikation) eines Steuergerätes. Es wurde vom ASAM e. V. (Association for Standardization of Automation and Measuring Systems) standardisiert und findet hauptsächlich Anwendung, um bei der Entwicklung und beim Test von Steuergeräten für Kraftfahrzeuge mit diesen zu kommunizieren. Having a standardized protocol for measurement and calibration allows for reusability of toolkits between different hardware and
