ESP32: No Ethernet implementation in Sming

[Asanga-Viraj]

Hi,

I am working on an ESP32 project which needs ethernet. I managed to work with esp-idf_V4.1.
I like to work with Sming because it is well structured and easy to use. I did it with ESP8266. When reading examples, I didn't see an example related to ethernet. Also, I tried to add ethernet config to a Sming sample project and got compiling error. It seems to be ethernet is not included in the Sming project.
When will it go to implement in Sming?

Thanks,
Asanga

@Asanga-Viraj I've started work on Ethernet support, see #2361. There are a lot of possible ethernet configurations so if there's a specific combination you're interested in we'll try to get that implemented.

@mikee47 Thank you for the reply. ESP32 Ethernet current implementations in idf_V4.1 example such as internal mac and some SPI chips LAN8720, IP101, DP83848 and RTL8201 are OK for now. My current project is interested in internal mac. If I got another chip, I will mention it here.
Thanks.

@Asanga-Viraj Were you able to use Ethernet with the latest additions in Sming?

Actually I modified the Sming to work with Ethernet.

• I created a file and I added the file "Kconfig.projbuild" file in resource folder to %(SMING_HOME)/Sming/Arch/Esp32/Components/esp32/project/main.

• Then I changes file "startup.cpp" in resource folder to %(SMING_HOME)/Sming/Arch/Esp32/Components/esp32/src.

• Added this line "esp_eth \ " into the "SDK_COMPONENTS" after "esp_common \ " in components.mk file located in %(SMING_HOME)/Sming/Arch/Esp32/Components/esp32

• make sdk clean
make sdk fullclean
make sdk-menuconfig #then exit
make sdk-menuconfig

• delete folder %(SMING_HOME)/Sming/out/Esp32/debug/lib

• make sdk all

If you can help me to attach the relevant files in this thread, I will do it.

@Asanga-Viraj With the current develop branch of Sming you can find the Basic_Ethernet sample which shows how to connect the embedded MAC + LAN8720 PHY. If you haven't yet updated to IDF 4.3, see https://sming.readthedocs.io/en/latest/_inc/Sming/Arch/Esp32/README.html.

To avoid any IDF-specific dependencies in applications I've created a C++ wrapper for the ethernet. See https://github.com/SmingHub/Sming/tree/develop/Sming/Components/Network/Arch/Esp32/Platform/include/Platform. Comments in the class header should be helpful. This is a new interface so please if you have any suggestions for changes or improvements let me know!

@mikee47 Thank you for the upgrade. I will let you know.

Feel free to re-open if you have issues with the Ethernet for ESP32 implementation.
