cpp_demo — XCPlite C++ API Demo

Demonstrates the C++ API of XCPlite including the calibration parameter segment RAII wrapper, measurement of member variables in class instances, signal generators with lookup tables, and the variadic all-in-one macro API.

What it demonstrates

Feature How it is demonstrated
C++ calibration RAII wrapper CalSeg<ParametersT> — segment locked/unlocked via RAII on scope exit
Measurement in class instances SignalGenerator member variables measured via DaqRegisterMember
Stack variable measurement Local variables registered and measured within member functions
Signal generator with lookup table LookupTableT — 2D calibration map with shared axis
Variadic macro API XCP_VAR(...), XCP_CAL(...) — compact registration in one call
Two independent instances Two SignalGenerator instances with separate events and parameter sets

Files

File Purpose
src/main.cpp Demo application — server setup, event loop, two signal generator instances
src/sig_gen.hpp/cpp SignalGenerator class — measures sine/square/saw waves
src/lookup.hpp/cpp LookupTableT — 2D lookup table with shared axis as calibration parameter
CANape/ CANape project (A2L auto-upload, XCP UDP, port 5555)
CANape_25/ CANape 25 project variant

Building

./build.sh examples
./build/cpp_demo

Or with CMake directly:

cmake -B build -S . -DXCPLITE_BUILD_EXAMPLES=ON -DCMAKE_BUILD_TYPE=Debug
cmake --build build --target cpp_demo
./build/cpp_demo

CANape

Open CANape/CANape.ini in CANape. The project is pre-configured for XCP on UDP, port 5555, with automatic A2L upload. If CANape cannot connect, verify the IP address in Device Configuration / Devices / XCP / Protocol / Transport Layer.

Note: If CANAPE_24 is defined in sig_gen.hpp, the lookup table uses a nested typedef with THIS. references to its shared axis.
