Spike: Evaluation of STM32 sensing capabilities for automotive mobility contexts

[Biltes]

Related issue(s): closes #354

Type of change

• spike: Investigation / research

Summary

This spike evaluates the STM32U585AI microcontroller for automotive mobility applications, focusing on sensor integration, real-time data processing, and CAN bus communication capabilities.

The document provides a comprehensive technical analysis of:

• STM32U585AI specifications and automotive-relevant features
• Sensor interfacing capabilities (IMU, environmental, proximity sensors)
• Real-time processing and CAN bus integration
• Power efficiency and security features

How to test / Validation

@Biltes
Is it supposed for the old sensor_selection being deleted and replaced by yours?
Maybe it should be moved to archive/
