Supporting ESP32_S3 using W5500 Ethernet

[avanderhoest]

Hey! Thanks for the lib!
I used the example ESP32_FS_EthernetWebserver and it works when I run it from Arduino IDE.
When I upload the code from PlatformIO, I get the correct logging :
Using mac index = 17
Connected! IP address: 192.168.1.221
FS File: favicon.ico, size: 1.12KB
...
HTTP server started @192.168.1.221
Open http://192.168.1.221/edit to see the file browser
handleFileRead: /

But my browser doesn't show the html pages. It is stuck on loading.

I use the same example code. Do you have any idea why code uploaded by PlatformIO doesn't serve the files?

ps. My setup is an WT32-SC01-PLUS board and I use an ethernet W5500 module.
Should I be using your WebServer_WT32_ETH01 lib instead?

Hi @avanderhoest

I used the example ESP32_FS_EthernetWebserver and it works when I run it from Arduino IDE.

and

code uploaded by PlatformIO doesn't serve the files

clearly show that there is some kind of issue with your settings, even some bug of PIO.

I suggest you post on PIO Forum to ask for help.

Good Luck,

[avanderhoest]

Wow thanks for your quick reply. I was even still updating my original question with the question if I should be using WebServer_WT32_ETH01 instead of ESP32_FS_EthernetWebserver?

Also, do you have a lib or example to use (AsyncWebsever)[https://github.com/me-no-dev/ESPAsyncWebServer] together with an ESP32 with Ethernet?

[khoih-prog]

For ESP32 Ethernet Async, use

1. AsyncWebServer_WT32_ETH01 for WT32_ETH01 (ESP32 + LAN8720)
2. AsyncWebServer_ESP32_ENC for ESP32_ENC (ESP32 + ENC28J60)

It's better to use Async, especially for ESP32 and ESP8266, if you have experience and expect higher performance. Check Why Async is better

[avanderhoest]

Thank you!
Do you also have a suggestion for WT32 with Ethernet W5500?
(I have WT32-SC01-PLUS)

[khoih-prog]

Try my brand new

1. WebServer_ESP32_W5500 for sync
2. AsyncWebServer_ESP32_W5500 for Async

libraries written for ESP32 + W5500

[avanderhoest]

amazing! I will try them!

[avanderhoest]

Hi Khoih!

I tried the Async webserver but no luck so far. I get:

I am quite sure about most PIN numbers because I got your ESP32_FS_EthernetWebServer example working:

I connected INT to the display pin next to CS. But I don't know about the SPI_HOST and the SPI Clock.

Also, I would need a local network with fixed IP so I think I need:

IPAddress myIP(192, 168, 1, 221);
IPAddress myGW(192, 168, 1, 1);
IPAddress mySN(255, 255, 255, 0);

// Google DNS Server IP
IPAddress myDNS(8, 8, 8, 8);

and :

  // start the ethernet connection and the server:
  // Use DHCP dynamic IP and random mac
  uint16_t index = millis() % NUMBER_OF_MAC;

  //bool begin(int MISO_GPIO, int MOSI_GPIO, int SCLK_GPIO, int CS_GPIO, int INT_GPIO, int SPI_CLOCK_MHZ,
  //           int SPI_HOST, uint8_t *W5500_Mac = W5500_Default_Mac);
  //ETH.begin( MISO_GPIO, MOSI_GPIO, SCK_GPIO, CS_GPIO, INT_GPIO, SPI_CLOCK_MHZ, ETH_SPI_HOST );
  ETH.begin( MISO_GPIO, MOSI_GPIO, SCK_GPIO, CS_GPIO, INT_GPIO, SPI_CLOCK_MHZ, ETH_SPI_HOST, mac[index] );

  // Static IP, leave without this line to get IP via DHCP
  bool config(IPAddress local_ip, IPAddress gateway, IPAddress subnet, IPAddress dns1 = 0, IPAddress dns2 = 0);
  ETH.config(myIP, myGW, mySN, myDNS);

  ESP32_W5500_waitForConnect();

but then I get an error saying:

conversion from 'int' to 'IPAddress' is ambiguous
   bool config(IPAddress local_ip, IPAddress gateway, IPAddress subnet, IPAddress dns1 = 0, IPAddress dns2 = 0);

Any pointers to how to continue? Thanks in advance!!

HI @avanderhoest

I have no compile error issue with static IP turned on for ESP32_S3 or even UM_TinyS3. So be sure to use the latest ESP32 core v2.0.5 and set compiler warning to Default (For Arduino IDE, File->Preferences->Compiler Warnings) as recent ESP32 core / Arduino IDE is so extreme to flag even common warnings as errors

2. The INT pin is absolutely necessary to use the library.
   So be sure to use it correctly. You can change INT from pin 10 (commonly used by many other libraries / parts) to another in to test and be sure it not conflicting.

Note:

Don't use GPIO10, change to another GPIO, such as IO4, IO5, etc.

Also it's better to try using Dynamic IP first, if you have issue with Static IP.

Only you can know and check the wiring to be sure correct.

[avanderhoest]

Hey! I am trying with Dynamic IP first indeed, but still no luck.

I changed INT from GPIO10 to GPIO15 but same result.

 esp_eth_mac_new_esp32 failed

I can't use other pins because I have the display, so my only free ones are 10 or 15. This is my setup:

The thing is with these pin numbers I got your example of ESP32_FS_EthernetWebServer working.

Is there any way I can debug more? Like get some more information on "esp_eth_mac_new_esp32 failed".

[khoih-prog]

1. Try with other different ESP32 boards to see the W5500 is working. The INT is absolutely necessary. The ESP32_FS_EthernetWebServer doesn't need INT to work
2. Buy new W5500, many different styles, to test and see which has working INT
3. Be sure the GPIO15 is not used be anything else

Sorry nobody can help you out here. Try to be investigative and innovative.

[avanderhoest]

Thank you!

I tried another esp32 board and got it working! so I'll try and figure out what was wrong with my original board. Thanks so much!

[avanderhoest]

Is the lib also suited for esp32 S3 boards? I would still very much like to make it work on my WT32-SC01-PLUS but so far no luck. Can I leave the Reset pin empty?

When I connect my W5500 to the display board, I can get your ESP32_FS_EthernetWebserver example working.

When I connect also the interrupt pin to run the AsyncWebServer_ESP32_W5500 code, then I get an error "esp_eth_mac_new_esp32 failed". I tried using PIN number 13 or 10. Both of these pins work when I use them for MISO in the ESP32_FS_EthernetWebserver code, so I assume they should be OK.

What is your setup with connections to the W5500 when you run the AsyncWebServer_ESP32_W5500 code? I leave RST, 1 GND and 5V open. I use the other GND and 3.3V.

[khoih-prog]

Hi @avanderhoest

Unfortunately, this EthernetWebServer library as well as many more, such as

• WebServer_ESP32_W5500
• WebServer_ESP32_ENC
• even in ESP32 core

don't support new ESP32_S3, ESP32_S2 and ESP32_C3 using LwIP Ethernet

OK to use with non-LwIP Ethernet_Generic library

I had to do some more researches, tests and figured out a fix and will create the new library to support specifically ESP32_S3, , ESP32_S2 and ESP32_C3 and will published soon

[avanderhoest]

Hi Khoih! Thanks so much for your quick replies, and all your work!
My ESP32_S3 already worked with your webserver library EthernetWebServer, but the issue is with the Async library AsyncWebServer_ESP32_W5500.

Is it possible to fix the issue there also?

[khoih-prog]

You can't use current AsyncWebServer_ESP32_W5500 for ESP32_S3, which strangely behaves differently from ESP32 and can't use the current LwIP library, such as WebServer_ESP32_W5500.

If necessary, I have to modify or write some new libraries, such as AsyncWebServer_ESP32_SC_W5500, specifically for ESP32_S3/2 and C3

Try this new AsyncESP32_SC_Ethernet_Manager to see if working for your ESP32_S3 before I'm moving forward.

[avanderhoest]

I tried and this is my output:

I think it's not enough output, it should also say local ip etc .

These PIN number work with the EthernetWebServer example so they should be correct.

Hi @avanderhoest

I'm moving this to the correct location @ Supporting TINYS3 using W5500 Ethernet #4

Try to use pin assignment defined in the board package um_tinys3 pins_arduino.h

static const uint8_t SS    = 34;
static const uint8_t MOSI  = 35;
static const uint8_t MISO  = 37;
static const uint8_t SCK   = 36;
