PYBv1.0

MicroPython version

Platform: pyboard
Version: 3.4.0; MicroPython v1.27.0-dirty on 2026-02-04

Reproduction

from machine import Pin
import time
import network

nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.Y12)
print(nic.ipconfig("addr4"))
led = Pin("Y6", Pin.OUT)

while True:
led.on() # 点亮
time.sleep(0.5) # 延时 0.5 秒
led.off() # 熄灭
time.sleep(0.5) # 延时 0.5 秒
