Hi 

 I would like to use the STM32F0 to run the MDIO\MDC in STM32F072C8, if can use the GPIO port to simultion the MDIO\MDC to PHY communication  or exmaples code can share with us .

thanks

I'd imagine could implement a GPIO bit-bang implementation, don't think you'd be able to hit 2.5 MHz.

Not sure there will be pre-packaged examples, review the specification, and code your own solution.

Hello Clive

thanks comments, if possible reach to 5MHz for MDIO interface or not?

Is there have code for reference to reduce coding time? thank you

For a write only interface you could probably use SPI to generate the signal, and clock that 5 MHz.
