Copyright © 2026 STMicroelectronics
This software is compatible with STM32 ISP IQTune v2.0.0 desktop application that can be downloaded here:
https://www.st.com/en/development-tools/stm32-isp-iqtune.html
Enhancements, new features
- Update STM32N6 HAL, CMSI and BSP to the version 1.3.0
- New 2A algorithms:
- The Auto-Exposure (AE) algorithm is now based on lux estimation, providing a faster and more stable approach to achieve the luminance target.
- The Auto White Balance (AWB) algorithm now uses color ratios to reach color accuracy more quickly and with greater stability. Additionally, this new algorithm offers improved rendering between two profiles through interpolation.
- New tuning parameters are now required to run the new 2A algorithms. These parameters are avalaible for the following list of sensors:
- IMX335
- VD66GY
- VD5943 (MONO)
- VD1943
- VD65G4
- VD56G3 (MONO)
- UVC feature:
- Support of USBx and Threadx
- Camera preview is now displayed using UVC live streaming
Limitations
- None

Release Notes for X-CUBE-ISP v1.1.0
Copyright © 2025 STMicroelectronics
Purpose
The X-CUBE-ISP package provides the functionnality to control and tune the
DCMIPP ISP present in the STM32N6xx products.
It contains:
- An embedded ISP Library middleware (running on the target) hosting 2A
algorithms (Auto Exposure and Auto White Blance) and mechanisms to control
the ISP and load sensor tuning file.
x-cube-isp/Middlewares/ST/STM32_ISP_Library - A tuning application (running on the target) that allows to interact
with the STM32 ISP IQTune desktop application executed on the host computer
and connected through usb.
x-cube-isp/Projects/DCMIPP_ISP/ISP_IQTune_App
To take control of the DCMIPP ISP:
- The host computer must execute the STM32 ISP IQTune desktop application and
connect to the target thanks to an USB-C cable on the USB1 (CN18) connector of
the board. - The ISP IQTune App must be loaded and launched on the target.
Key Features
- Control of all ISP parameters via desktop application
- Image analysis function for camera sensor tuning
- Generation of sensor ISP tuning file
- Embedded Auto Exposure algorithm (AE)
- Embedded Auto White Balance algorithm (AWB)
- STM32 ISP IQTune application
Update history
Enhancements, new features
- Update STM32N6 HAL, CMSI and BSP to the version 1.1.0
- Add sensor delay feature that can be manually set or automaticaly computed thanks to the STM32-ISP-IQTune desktop application
- Improve AWB algorithm to avoid flickering between 2 illuminants
- Add AEC anti-flicker feature that support 50Hz and 60Hz region.
- Statistic area has been remove from init parameter of the ISP_Init() function
- Fix IAR build warnings in the evision libraries
Limitations
- None
