%% XCP Data Acquisition over CAN % This example shows you how to use XCP blocks to directly acquire % measurement values from a slave in Simulink(R). It uses an XCP slave % simulator available for free download from Vector, and Vector Virtual CAN % channels. % % Vehicle Network Toolbox(TM) provides Simulink blocks for acquiring % measurement values from a slave via Simulink models over Controller Area Networks % (CAN). This example uses the XCP Configuration, XCP Data Acquisition, and % XCP CAN Transport Layer blocks to perform data transfer over a CAN bus. %% % Copyright 2012-2013 The MathWorks, Inc. %% % % <<../demoVNTSL_XCPCANCommunication_Model.png>> % %% Run a Slave Simulator % For this example, you must install a third party XCP Sample implementation % from Vector. This includes a slave simulator and an A2L file. To install % this free implementation: % % # Go to www.vector.com and navigate to the "DOWNLOADS" page. % # Search for "Demos" under "Categories" and "XCP" under "Standards". % # Download and install the available version of "XCP Sample % Implementation". % # In MATLAB, navigate to where you installed the sample package, and % then go to .\Samples\XCPSim\CANape. % # The MATLAB XCP examples will use the XCPSIM.a2l file and the % XCPsim.exe slave simulator. Run XCPsim.exe. %% Setting up XCP Block Parameters % Create a model to set up XCP data acquisition for the measurements, % Triangle and PWM, from the slave. % % * Use an XCP Configuration block and select the A2L file, XCPSim.a2l % * Use an XCP CAN Transport Layer block and set the Device to Vector % Virtual Channel 1. The transport layer is configured to transfer XCP % messages over CAN via the specified virtual channel. % * Use XCP Data Acquisition blocks to receive selected measurements at % specified events. For this example we have selected an XCP Data % Acquisition block for each measurement of each selected event. %% % % <<../demoVNTSL_XCPCANCommunication_Subsystem.png>> % %% Visualize Measurement Values Received From Slave % Plot the results to see the measurement values for Triangle and PWM from % the slave. The X-axis corresponds to the simulation timestep. % % <<../demoVNTSL_XCPCANCommunication_Scope.png>> %
