Quarc — Library Simulink

The real-time constraints (e.g., avoiding infinite loops, stack overruns) can trip users new to hard real-time systems.

blocks allow for direct access to data acquisition cards. Users can switch hardware targets for an entire model by modifying a single parameter. Real-Time Performance : It supports hard real-time execution

What specific or DAQ board are you trying to interface with?

To make your "piece" functional with hardware, you typically need these blocks: quarc library simulink

Standard Simulink Scopes display hardware data instantly via External Mode. Manual thread allocation and mutex programming.

When using communications blocks, use shmem:// (shared memory) for processes on the same PC to get the lowest possible latency.

: Select the QUARC target (e.g., quarc_win64 ) in the Model Configuration Parameters. The real-time constraints (e

Used for reading sensor data (encoders, analog inputs) and writing to actuators (motors, PWM outputs).

The QUARC library is a suite of tools developed by Quanser that integrates with MATLAB and Simulink to enable rapid control prototyping and real-time hardware-in-the-loop (HIL) simulations. It allows users to generate real-time C code directly from Simulink models and run it on various hardware targets without manual programming. Key Papers and Documentation

QUARC allows you to run asynchronous, multi-threaded tasks. You can run high-frequency control loops (e.g., a 1 kHz motor controller) alongside low-frequency tasks (e.g., a 10 Hz user interface or data logger) within the exact same model without dropping samples. Step-by-Step Workflow: Deploying a Model with QUARC Real-Time Performance : It supports hard real-time execution

This section manages data transfer between different targets, computers, or external smart sensors.

Connect the output of your controller to an block to command the motor amplifier. Step 4: Build and Run in Real-Time
