unable to compile to DOIT esp32 DEV KIT

I have been trying to compile the code for esp32 and enc28j60 as an ftp client to receive the data. but throws the following error
Using board 'esp32doit-devkit-v1' from platform in folder:

HI @KvarTechnologies

The library currently is not supporting ESP32 using Ethernet (W5x00 or ENC28J60).

I'll modify and release a new version to add that support within today.

Best Regards,

[khoih-prog]

Hi @KvarTechnologies

The new FTPClient_Generic v1.4.0 has just been published in both Arduino IDE and PIO. Your contribution is noted in Contributions and Thanks.

Please test and continue reporting any more issue

Best Regards,

---

Releases v1.4.0

1. Add support to ESP32/ESP8266 using Ethernet W5x00 or ENC28J60 with Ethernet_Generic or EthernetENC library
2. Add astyle using allman style. Restyle the library
3. Update Packages' Patches

---

Notes

You can only use EthernetENC library for ENC28J60, not the old and deprecated UIPEthernet

Just changing these lines from

FTPClient_Generic/examples/Ethernet/FTPClient_DownloadFile/defines.h

Lines 363 to 367 in 36e9fb7

	// Only one if the following to be true
	#define USE_ETHERNET_GENERIC true
	#define USE_ETHERNET_ESP8266 false
	#define USE_ETHERNET_ENC false
	#define USE_CUSTOM_ETHERNET false

to

// Only one if the following to be true
#define USE_ETHERNET_GENERIC  false
#define USE_ETHERNET_ESP8266  false
#define USE_ETHERNET_ENC      true
#define USE_CUSTOM_ETHERNET   false

I just had a test using ESP32 + W5500 with the result here

The example file is compiling and able to upload to esp32_ dev board. As suggested USE_ETHERNET_ENC enable by the True, but serial monitor stops after printing following

I suggest you test your board and ENC28J60, with the basic examples using EthernetENC library first.

Post the successful results here before moving on with this library.

FYI, I'm testing here and OK. Possibly your wiring, boards, etc.

Thanks for the support, your library is now compatible with the ESP32 Dev board. A small suggestion, it will be great if there would have been a flag to state the connected or disconnected, it waits for a quite a long time for reconnecting. Function to start a connection, if not connected don't move for the further process
