Currently we are using STM32F4 & STM32H7 controller with inbuilt ethernet. We are looking to add a profinet interface in our device without using additional external hardware.
Please can you share references or documents how can we integrate Profinet stack on STM32F4 & STM32H7 hardware. Also share us the official and available Profinet stacks which we can use without using extra hardware on STM32F4 & STM32H7 .
Please share the references and guides, It will be helpful.
