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

Enhancements, new features

• Support for camera > 5 MP
• New tuning parameters are available for:
  • VD65G4
  • VD66GY
  • VD1943
  • IMX477 (New supported Camera)
• Update to HAL 1.4.0
• Enhance 2A algos with a new convergence speed parameter
• Double buffering to avoid tearing
• Add Preview app which only shows an example on how to use the CMW + ISP in a simple application
• Some Bug fixes
• Use An FSBL for boot from flash mode (see Doc/Boot-Overview.md)

Compatibility

Compatible with STM32 ISP IQTune 2.1.0 (No backward compatibility with previous STM32 ISP IQTune version).
