Pure-Python interface for WIZNET 5k ethernet modules.
Project description
Introduction
Pure-Python interface for WIZNET 5k ethernet modules.
NOTE: This library does not currently contain a DNS client. You will need to include a server ip address and destination port in your code.
Dependencies
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-wiznet5kTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-wiznet5kTo install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-wiznet5kUsage Example
This example demonstrates making a HTTP GET request to wifitest.adafruit.com.
import time
import board
import busio
import digitalio
from adafruit_wiznet5k.adafruit_wiznet5k import WIZNET
import adafruit_wiznet5k.adafruit_wiznet5k_socket as socket
# Name address for wifitest.adafruit.com
SERVER_ADDRESS = (('104.236.193.178'), 80)
cs = digitalio.DigitalInOut(board.D10)
spi_bus = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
# Initialize ethernet interface with DHCP
eth = WIZNET(spi_bus, cs)
print("DHCP Assigned IP: ", eth.pretty_ip(eth.ip_address))
socket.set_interface(eth)
# Create a new socket
sock = socket.socket()
print("Connecting to: ", SERVER_ADDRESS[0])
sock.connect(SERVER_ADDRESS)
print("Connected to ", sock.getpeername())
# Make a HTTP Request
sock.send(b"GET /testwifi/index.html HTTP/1.1\n")
sock.send(b"Host: 104.236.193.178\n")
sock.send(b"Connection: close\n\n")
bytes_avail = 0
while not bytes_avail:
bytes_avail = sock.available()
if bytes_avail > 0:
data = sock.recv(bytes_avail)
print(data)
break
time.sleep(0.05)Contributing

This library was written by Arduino LLC. We’ve converted it to work with CircuitPython and made changes so it works similarly to CircuitPython’s WIZNET5k wrapper for the WIZnet 5500 Ethernet interface and CPython’s Socket low-level networking interface module.
