Hello, I am using already FreeRTOS+TCP in an STM32H743ZIT6 uC with a LAN8742 PHY. For a PCB which is exposed to High Voltage (2kV) I would like to exchange the PHY and use the 10/100 Mbps Ethernet over an SC/ST or SCP fiber optic interface. I am considering for that matter the DP83822 PHY. Is it supported by FreeRTOS+TCP for the STM32H7?, if not, are there other tested alternatives compatible with optical interfaces?
I don’t know if anyone has written and submitted a driver for it, but that is one advantage of FreeRTOS and its support libraries being open source, you can always write your own, and to be nice, submit it so others can use it.
Thanks for the answers. I’ve seen already the list of PHYs, what I was wondering is if somebody has used already successfully a DP83822. I would have to redesign and relayout the PCB and therefore it would be good to know upfront about previous experiences
Maybe it’s better to get some evaluation board before “modify the PCB”. So you are experienced in this before actually developing. And I would suggest, try STM32CubeMX for the software of Ethernet. It’s wonderful, in my personal opinion.
