1. What is the STM32 ISP IQTune desktop application?

IQTune.png
 STM32 ISP IQTune is a comprehensive STM32 ISP tuning software application offering a wide range of features and services to help professional and nonprofessional STM32 users tune an embedded ISP.

It consists of two components:

  • A desktop application, running on a host computer (Linux Ubuntu, Windows or MacOS)
  • An embedded application, running on the STM32 device to be tuned.

These two components communicate through a USB link connecting the host computer to the STM32 board to be tuned.

STM32 ISP IQTune provides all the services to allow users to tune the STM32 ISP for an RGB RAW Bayer sensor and its associated lens:

  • It gives access to the STM32 ISP parameters that can be tuned.
  • It provides image quality analyzing capabilities to easily tune the STM32 ISP for any light conditions. For a white-balance profile, the image quality analyzing services provide:
    • The possibility to define the white-balance ISP gain.
    • The possibility to define the color correction matrix.
    • Information and metrics about the color accuracy according to the ISP configuration defined by the user.

2. How to install STM32 ISP IQTune

Go to st.com to download the STM32 ISP IQTune software for your OS:

  • Windows : STM32-IQTune-Win
  • MacOS : STM32-IQTune-Mac
  • Ubuntu : STM32-IQTune-Lin


Run the installer, which automates the installation process and ensures that all necessary files, settings, and dependencies are properly configured for your system.

On Ubuntu, .AppImage is a self-contained application, so there is no need to install it.

3. How to use STM32 ISP IQTune

3.1. Connect the board

Connect the host computer running the STM32 ISP IQtune desktop application to the target USB Type-C (OTG) port with a USB cable.

3.2. Launch the board application

  • Run the STM32 ISP IQTune application to:
    • Start the camera preview.
    • Prepare the USB connection with the remote desktop application.
IQTune_target

3.3. Launch the desktop application

When the application is launched, it first checks for the USB connection with the remote embedded application.

IQTune_start_wait_device

As soon as the remote embedded application has started, the connection port is detected. Click on Connect.

IQTune_start_connect_device

The application starts and displays the following:

  • The right-hand Live Feedback panel displays feedback of the image displayed on the target, allowing you to make ISP adjustments and see changes.
  • Useful sensor information is displayed in the bottom left panel.
  • The tuning procedure can be started with the Start tuning from scratch button in the top left panel.
