I2C slew rate limiter

Hello everyone,

Is there a setting/command to limit the slew rate of I2C signals of a STM32F429ZI-Disco board? I know this feature is available on some Microchip micro-controllers.

Thank you.

Essentially, for each GPIO and thus also for the I2C pins, you can set the maximum output speed between Low/Medium/High/Very High, which has a direct influence on the slew rate.

Does it answer your question?
