RPC Interface Library POE Board

Postby JackBonnell » Mon Nov 09, 2020 10:13 am

Hi,
I've been working on a a POE shield for the OpenMV H7 I have the power issues fixed, The main issue i am having is how to attach the SPI to the Ethernet port:

Code: Select all

rpc_wifi_or_ethernet_slave(my_ip="", port=0x1DBA)
I am unsure of the use of this do i need to have a ethernet chip to sub such as this?

any help would be appreciated.

Hi, MicroPython has a driver already for the WINZNet 5K: https://github.com/openmv/micropython/t ... s/wiznet5k

I would use that chip... as it would be a very minimal amount of work to get it operational.

It's already supported in the STHAL for MicroPython: https://github.com/openmv/micropython/b ... wiznet5k.c

...

A compile flag has to be enabled to include it. But, otherwise it's almost there.

Thank you for the quick reply can the compile flag be enabled in the openmv firmware?

Yeah, that isn't a problem. We just need firmware space.
