[Arduino IDE demo source code for KC868-A16]--#09-KC868-A16_Web_server_code

[wolli]

Hello

I have a KC868-A16

I've recently performed an update


KCS_KC868_A16_V2.2.2.bin


The LEDs on the Ethernet interface are now lit

but I still get the error message

if you have downloaded KCS firmware, just directly to use board, NOT need to use arduino.

[wolli]

Yes, that's true, but it was meant to be a test!

I have a finished Arduino program!

My program runs perfectly with WiFi!

But I'd rather connect via Ethernet!

But when I include
#------------------------------------------------

#include <WebServer_WT32_ETH01.h>

#------------------------------------------------
I always get the error message!!!

#-----------------------------------------------------------------------------------------------------------

#-----------------------------------------------------------------------------------------------------------
The yellow and green LEDs on the Ethernet port are always off.

I need your help. I've tested various programs in the examples, and I always get the same error.

Hi,

I had the same issue than @wolli.

It looks like the WebServer_WT32_ETH01 library is incompatible with versions 3.x of Board Manager from ESP32 Espressif.

If you install version 2.0.17 of Board Manager from ESP32 Espressif and use the code from https://www.kincony.com/forum/showthread...31#pid8831 it compile and work fine.


Anyway, it will be good if Kincony support will find a way to use the recent versions Board Manager from ESP32 Espressif.

Hi
Thank you very much for your reply
lusant@

Now I can load the sketch but
I get an error message,

-----------------------------------------------------------------------------------------
Starting WebClient on ESO32_Dev with ETH_PHY_LAN8720
Webserver_WT32_ETH01 v1,5,1 for core v2.0.0
E (1024) esp.emac: emac_esp32_init(357): reset timeout
E (1024) esp_eth: esp_eth_driver_install(214): init failed
---------------------------------------------------------------------------------------------
and that for both example scripts

I would be grateful for further help
