我用 esp32 协处理器举起了羽毛。esp 通过 spi 连接，我用这个库“adafruit_esp32spi.adafruit_esp32spi_socket”创建了一个套接字。通常我会收到至少 200 个包裹，但在某些时候，它会停止工作。使用 socket.recv(1500) 我读出了缓冲区，但它总是空的。你们有没有类似的问题？你怎么修的。我喜欢circuitpython，但它看起来很糟糕，偷走了它的乐趣。

如果重要：我在 art-net 协议中接收 25fps 来控制 LED 矩阵

我缩短了代码，但问题仍然存在......

TIMEOUT = 5  # time out socket
HOST = "192.168.4.1"  # listing for this host
PORT = 1030  # listing on this port from the host

### imports ###
import time
import board
from digitalio import DigitalInOut
from adafruit_esp32spi import adafruit_esp32spi
import adafruit_esp32spi.adafruit_esp32spi_socket as socket
import udp_decoder
import neopixel


# Get wifi details and more from a secrets.py file
# adafruit standard
try:
    from secrets import secrets
except ImportError:
    print("WiFi secrets are kept in secrets.py, please add them there!")
    raise


### wired pins ###
# to esp32
spi = board.SPI()
esp32_cs = DigitalInOut(board.D13)
esp32_ready = DigitalInOut(board.D11)
esp32_reset = DigitalInOut(board.D12)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)


connected = 0
while not connected:
    try:
        # connect to wifi AP (RPI)
        esp.connect(secrets)
        print(connected)
        connected = 1
    except:
        print("Tryng to connect again")

print("My IP address is", esp.pretty_ip(esp.ip_address))
# test for connectivity to server
print("Server ping:", esp.ping(HOST), "ms")


# create the socket
socket.set_interface(esp)
socketaddr = socket.getaddrinfo(HOST, PORT)[0][4]
s = socket.socket(type=socket.SOCK_DGRAM)
s.settimeout(TIMEOUT)

s.connect(socketaddr, conntype=esp.UDP_MODE)


ii = 0

while 1:
    print("looping")#see if still alive
    # amount = s.available() # also not vorking

    amount = s.recv(1500)
    if amount:
        # here would be my code
        print(ii)
        ii += 1
        time.sleep(0.0025) #estimated time for neopixel control of my matrix
