1.1.0

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
