If not specified, the default is 'localhost:7701'. qspy_host - optional host-name/IP-address:port for the host running the QSPY host utility.If not specified, qview will provide only the generic user interface for interacting with the target (e.g., reset, setting QS filters, posting events, etc.). cust_script - optional customization Python script for your specific target system.If you are using QView™ as a standalone Python script, you invoke it as follows: python3 /qview.py ]]Īlternatively, if you've installed QView™ with pip, you invoke it as follows: qview ]

Also, the QTools™ collection for Windows already includes Python (3.8), so you don't need to install anything extra.Īlternatively, you can use your own Python installation, into which you can install the latest QView™ with pip from the PyPi index by executing the following command: pip install qview Note The qview.py script is included in the QTools™ collection. The qview.py script can be used standalone, without any installation in your Python system (see Running QView™ below).

Remarks Why UDP? The communication between QSPY and QView is based on UDP, because UDP is inherently packet-oriented (as opposed to TCP, which is stream-oriented) and preserves the packet boundaries. This communication ( blue arrows) uses the same packet structure as the QP/Spy Protocol, but without the HDLC framing, without transparency (escaping), and without the checksum. The QView™ (Python script) attaches to the QSPY host application by means of the UDP socket that QSPY opens specifically for attaching various "front-ends". Additionally, the QP/Spy implementation in the Target must support bi-directional communication with QSPY.

Attention The Target must be running the "Spy" build configuration, in which the QP/Spy™ Software Tracing is enabled. This communication is based on the QP/Spy Protocol.

The embedded Target is running an instrumented code that communicates with the QSPY Host application over the Target data link ( red arrows). The sequence diagram below shows the general structure of QView™. Note A visualization and monitoring system like QView™ can be used in all stages of development, during manufacturing, and also after deployment for in-field servicing of embedded devices.

Poke data (supplied from QView™) into the Target.

Peek data inside the Target and send to QView™.

Execute a user-defined command function inside the Target with arguments supplied from QView™.

Inject an arbitrary event to the Target (direct post or publish).

Set global QS filters inside the Target.

Out of the box, QView™ supports the following commands ( NOTE: This basic functionality can be extended in the QView™ customization): The cusomization is accomplished in Python (version 3), which means that it is naturally platform-neutral and runs without any changes on Windows, Linux, or macOS.

Change USB Connect Setting and USB LUN Setting of the camcorder.QView™ has been specifically designed for extensibility, so that you can quickly customize its GUI and behavior to your specific embedded project, so that you can use QView™ as a powerful custom Human-Machine Interface (HMI) for your projects.

If other options like internal memory, internal hard disk, or memory card are displayed on the LCD screen other than the USB CONNECT option, choose the icon where the images or videos you want to transfer are located.

If USB SELECT is displayed on the LCD screen of the camcorder, choose USB CONNECT.

If Check the connected device is displayed on the LCD screen of the camcorder, it is possible that the USB cable is disconnected or has lost connection.

If USB connected, MTP connected, or Mass Storage connected is displayed on the LCD screen of the camcorder, the camcorder is recognized by the computer.

Not all camcorders with a USB connection support USB Streaming.

Once powered on, some camcorder models require you to select USB CONNECT or COMPUTER on the LCD screen.

If you have a camcorder with USB Streaming capability, you may also need to turn on the USB Streaming feature in the camcorder menu.
