Howto implement I2C slave clock stretch timeout.

[MScho.15]

Hi,

I like to implement a I2C slave on a STM32G081 with using stm32cubeide.

Basically, it is working.

Sometimes, the system communication stuck while a transaction on the STM32 I2C slave is active.

How can I implement a clock stretch timeout on slave side. Is there any other special error handling needed?

Is there any example regarding this?

My Code:
