ESP32-ENC28J60

ESP32-ENC28J60 copied to clipboard

hi , I'm using the ETH_ENC28J60 example , and directly flash to esp32dev module without changing program, I'm using node MCU ESP-32s v1.1 development board. The program always restart after connection started. also use the same 10 pin ethernet module mentioned in this document,

Ethernet LAN module connected with esp32 according to the configuration

#define SPI_HOST 1 #define SPI_CLOCK_MHZ 8 #define INT_GPIO 4

#define MISO_GPIO 12 #define MOSI_GPIO 13 #define SCLK_GPIO 14 #define CS_GPIO 15

Serial monitor always shows like this

Rebooting...

please help me to solve this problem thank you

hi, thanks for your feedback

The example has been tested with an esp32-wroom with the exact same pin settings, using arduino-esp32 2.0.5.

Can you confirm that the example sketch wasn't modified, and nothing else but the ENC28J60 was connected to the ESP32 during your test?

I suggest you use the Exception Decoder to get more info on this stack trace.

The Stack canary watchpoint triggered part in the error message only hints at a memory exhaustion in the stack, and decoding the exception could tell if this happens in loop() or in another task:

Things you can try:

• Check the wiring: do you have exactly 7 short wires flying between the ethernet module and the esp32?
• Use the other spi bus: #define SPI_HOST 0
• Confirm the problem also happens with one of the other libraries implementing ENC28J60:
