STM32 ISP Library

The ISP Library middleware (running on the target) hosts 2A algorithms (Auto Exposure and Auto White Balance) and mechanisms to control the ISP and load sensor ISP tuning file.

The STM32 ISP Library also implements a communication mechanism with the STM32 ISP IQTune desktop application that provide services to tune the ISP present in STM32 devices. To activate this communication through USB link, the compilation flag ISP_MW_TUNING_TOOL_SUPPORT must be enabled.

Structure

• isp: core of the ISP Library with the ISP parameter configuration
• isp_param_conf: collection of sensor tuning parameters
• evision: 2A algorithms that are delivered as binary

Enhancements, new features

• Fix dump issue while using the STM32 ISP IQTune desktop application in a windows environment
• Fix IAR build warnings

Known Issues and Limitations

• In some situations, Auto White Balance (AWB) algorithm can flicker between 2 AWB profiles*

\* Fix is under preparation
