How to add a "LAN8720" driver?

DK.7 · ‎2021-11-19

I have a ethernet module "LAN8720" and I have STM32H743VIT8. But MCU has only "LAN8742" driver. Is it possible to add the "LAN8720" driver to the list of drivers?

You can take the driver from the ARM CMSIS collection, here.

Thank you for answer, and in what folder I have to put it for appear it in the list of "Driver_PHY"?

Put the .c and .h files in any place where you like.

Then add them to your project manually and call from your ethernetif.c.

Let the Cube/CubeIDE think that you use LAN8742.

For your code they are compatible. But there is a bug in CubeMX:
