[info] lwip demos on Eth Phy ( ESP32 RMII ) runs
Posted: Mon Feb 27, 2017 12:16 am
hi
since we have the RMII on ESP32 working and we drive a Eth Phy Nic,
the pull request is done,
we can now do "same" doings like we do with services on wifi.
we can example run on the Eth Phy a web server, echo server, udp server .. and more
we can play with all lwip examples very easy.
found a repo as example here
there are more lwip examples on internet, try to search for "lwip examples"
i push a picture from my desk , sry for craz output, but we are in work alkoholic now
what you must do that the thing is working:
example http server:
and example TCP echo
copy the c and h file to your LAN8720 / TLK110 main folder
include the header in your main.c file
in the app_main call the init example
you have now a http server and a tcp echo server on eth phy rmii from esp32
how cool is that ?
best wishes
rudi
hope the info is welcome and helps
now we go on to build a gateway..
