W5500/SPI Ethernet Support (T-ETH-Lite-S3)

[troyhacks]

W5500/SPI Ethernet support, currently hardcoded for the T-Eth-Lite-S3 board - which is the only S3 board I know of with Ethernet:

https://www.lilygo.cc/en-ca/products/t-eth-lite

Needs lib_deps:

https://github.com/troyhacks/ETHClass2 (for W5500 support)
https://github.com/troyhacks/TroyHacksAsyncUDP (fixes a bug with AsyncUDP, backports some fixes from IDF v5.1)

Also likely needs IDF v4.4 to work correctly. Tested on v4.4.6.

Updated to use the new ETHClass2 - so there's a bunch of code ifdef'd out if it's an ESP32-S3 just to work around the fact that SPI Ethernet isn't really a thing we're accounting for at the moment in WLED - so I'd consider this a proof of concept, even if it works.

May be useful (not in this state) for adding SPI Ethernet to WLED for the original ESP32?

Hi @troyhacks .
If you need someone to test, I will be happy to help.
I am hopefully the lucky owner of Lilygo T-ETH-Lite-S3. I also have XIAO ESP32S3. In my case, they are supposed to work via I2S with WM8782S and PCM1808 ADC and DIR9001 SPDIF to I2S.
My programming skills are rather poor and I can't wait for support for T-ETH-Lite-S3 via ethernet, unfortunately my XIAO ESP32S3 somehow does not manage to stream the audio signal to the rest of the ESP32 via wifi.
Regards Janusz

This is great, thanks @januszwoj !

Just to assess the level you can help here, do you know how to build WLED from the source code and upload the resulting firmware to the ESP32-S3?

Hi @troyhacks
I'm not very good at it yet, but I manage to do it from time to time.
Sometimes I have trouble understanding where some things come from, but I'm trying to learn.
I use Visual Studio and Platformio to compile the firmware myself.

Hi @troyhacks
I have been trying for several days to compile a program for esp32S3 with w5500 support from your Github: "W5500_Support."
After adding the switche: -D WLED_USE_ETHERNET; at first I received messages that it's missing <ETHClass2.h> library.
I've added the libraries: ETHClass2 & TroyHacksAsyncUDP from your Github to the lib_deps in platformio.
Thanks to this, the messages about the missing library disappeared. Unfortunately, a different message appeared now:

.pio/libdeps/esp32S3_8MB_S/ETHClass2/src/ETHClass2.cpp: In member function 'bool ETHClass2::beginSPI(eth_phy_type_t, uint8_t, int, int, int, int, int, int, spi_host_device_t, uint8_t)':

.pio/libdeps/esp32S3_8MB_S/ETHClass2/src/ETHClass2.cpp:403:15: error: 'digitalPinToGPIONumber' was not declared in this scope

 _pin_cs = digitalPinToGPIONumber(cs);

So far I haven't been able to figure out a way to jump over it.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
