adafruit-circuitpython-wiznet5k 1.0.0a1

Pure-Python interface for WIZNET 5k ethernet modules.

Introduction

Pure-Python interface for WIZNET 5k ethernet modules.

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

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-wiznet5k

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-wiznet5k

To 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-wiznet5k

Usage 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

cs = digitalio.DigitalInOut(board.D10)
spi_bus = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)

# Initialize ethernet interface with DHCP
eth = WIZNET5K(spi_bus, cs, debug=True)

print("DHCP Assigned IP: ", eth.pretty_ip(eth.ip_address))

socket.set_interface(eth)

host = 'wifitest.adafruit.com'
port = 80

addr_info = socket.getaddrinfo(host, port, 0, socket.SOCK_STREAM)
sock = socket.socket(addr_info[0], addr_info[1], addr_info[2])

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)
