maybe you have not chosed correct "board" in arduino IDE. need use board -- "NodeMcu-32S"

I did actually. But I have never plugged the board phsically or bind the COM yet.
RE: [Arduino IDE demo source code for KC868-A32]--#08-Ethernet_LAN_Web_server - admin - 03-03-2023
do you have use ESP32 board v2.0? i think you can try to use ESP32 board V1.0.6 for a test.

No actually.
I am just a java programmer, I do not have many inventory.
Although I have EEE diploma, I am just good with screw driver trainning
That is why, I really want to use this board.
But i feel think the fix is, somehow written here.
I just have to do a controlled experiment with copying files and such.

my means: do you have installed "ESP32 v2.0 board" in arduino IDE.
not error "WebServer_WT32_ETH01.h: No such file or directory" , is wrong of your arudino environment.

For the product: KinCony KC868-A32 Rev:1.2
With arduino: 2.0.4
With the custom libraries below:
CF8574_library.zip
WebServer_WT32_ETH01 (click Code button, and download zip)
When I open up the arduino, It wants to update the custom libraries. I Updated
Then I restarted the Arduino.
Then, I could able to compile the project with below warnings:

can you test with arduino IDE 1.8.19. i am tested with this version.
RE: [Arduino IDE demo source code for KC868-A32]--#08-Ethernet_LAN_Web_server - tugalsan - 03-08-2023
(03-06-2023, 10:29 AM)admin Wrote: can you test with arduino IDE 1.8.19. i am tested with this version.
I installed IDE 1.8.19, and compile. As you have mentioned, there was no compile warning.
Then i looked at prefrences, Compiler warnings are set to none.
If I change it to Default manually, you can see the warnings.
I think, warnings are not important enough that, IDE 1.8.19 comes with CompilerWarning set to None.
Hence, it can compile, ok.
