ESP32 Forum

Hi
I am working on Ethernet project using W5500 and example common_components/protocol_examples_common.
And there is a few problem, in default configuration for SPI CLK PINis GPIO 20 is choosen, but i can't find this pin.
Is there any connection requirments like max cable length or specific pins to connect W5500 to ESP32?
Also default configuration for SPI_CLK is 36MHz but if i used that i get error about it should be use spi in half duplex mode?
Could someone tell me more about this?
Thank you.
Daniel

Hello,
which demoboard or module do you use?
SPI is rather internal interface so You should prepare approprite PCB or short wires to testing
Do you check setting configuration in menuconfig/sdk.cfg file?
