QUARC 2021
These release notes describe the new features and changes introduced in QUARC 2021. They are divided into the sections enumerated below.
New Software Compatibility
QUARC 2021 has introduced compatibility with the following third-party software.
Compatibility with MATLAB, Simulink, and Simulink Coder R2021a has been added.
New Features
The new features introduced in QUARC 2021 are mentioned below.
Toolchains support for all QUARC targets have been added. Toolchains provide better support for building generated code from MATLAB/Simulink toolboxes. It also support MATLAB Coder to build generated code from MATLAB scripts that can be run on QUARC targets.
Note that the use of toolchains would make the Simulink model to be incompatible with previous QUARC versions. Therefore for backward compatibility, a new QUARC menu entry is added to convert the model back to using non-toolchain build process.
New Devices Supported
QUARC 2021 may now interface to the devices listed below.
Support for the YDLIDAR X4 has been added to the Ranging Sensor block.
New Blocks
New blocks have been added to the QUARC Targets library in QUARC 2021. The new blocks are listed below.
Devices Blocks
The Force Torque Sensor block reads a force/torque sensor.
Sources Blocks
The File Read block reads a file from the local file system.
New Functions
New MATLAB functions have been added to the QUARC MATLAB functions in QUARC 2021. The new functions are listed below.
Script Functions
New script functions allow MATLAB scripts to be built to run on QUARC targets.
The new qc_build_script MATLAB function builds a MATLAB script for a target.
The new qc_run_script MATLAB function downloads and runs a script executable on a target.
The new qc_script_console MATLAB function opens a console to monitor a script executable's standard input and output.
Improved Features
Some of the features improved in QUARC 2021 are enumerated below. There are a great many miscellaneous improvements that have not been listed. Only some of the highlights are listed below.
The Quanser QArm card now supports all expandable I/O features found on the end-effector DAQ! With this latest firmware release, users can now take full advantage of the end-effector’s functionality, providing access to plenty of digital I/O and analog inputs. All of the expandable I/O features are listed below:
The QArm also now supports watchdog timers for resetting Digital, PWM and Other output channels on watchdog expiry.
Please visit the QArm Help Page for more information.
The video_capture_open and video_capture_read functions (for the Multimedia C API) and the VideoCapture.open and VideoCapture.read methods (for the Multimedia Python API) have been updated so that the image buffer does not need to be passed in to the open function, but instead is passed in to the read function.
Improved MATLAB Coder support for HIL.
Fixed the issue in the Computation Time block where it was not always computing the correct time when there was more than one subrate task.
The accuracy of the Sleep block has been improved by taking into account inaccuracies in Windows timing, particularly with more recent Windows updates.
Miscellaneous
The following shows the miscellaneous changes in QUARC 2021.
The Quanser Interactive Labs (QLabs) can now be installed as part of QUARC. QLabs provides collections of virtual hardware to that can be interfaced with QUARC.
