I have a W5500 chip on my custom board. When i plug in the ETH cable the LED not blink both Link and Act.
I try to check follow this topic Link LED - #2 by Coccoliso check all bias resistor i can’t solve my ploblem.
Would 1k resistors provide enough current for the LEDs to be lit?
Why 50 Ohms instead of required 49.9 1% Ohms? Are they 1%?
Why 6.8 picofarads instead of 6.8 nanofarads?
What “ferrite” is used here?
Is chip accessible through SPI?
this case my MCU can access the W5500 chip. i use same controller and wire to W5500 module (i got it from alibaba) it 's work.
In circuit ferrite is 33Ohm. i use 50Ohm resistor because it’s best i can find in my local seller.
but capacitor is my wrong i will fix it first.
