Hi everyone,
I’m working on an STM32F4-based project and facing inconsistent I2C communication stability between the MCU and an external sensor. The issue appears mainly when the sensor performs clock stretching, which causes the STM32 to miss data or stall the bus.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
