.. module:: network
|
|
:synopsis: network configuration
|
|
|
|
This module provides network drivers and routing configuration. Network
|
|
drivers for specific hardware are available within this module and are
|
|
used to configure a hardware network interface. Configured interfaces
|
|
are then available for use via the :mod:`socket` module.
|
|
|
|
For example::
|
|
|
|
# configure a specific network interface
|
|
# see below for examples of specific drivers
|
|
import network
|
|
nic = network.Driver(...)
|
|
print(nic.ifconfig())
|
|
|
|
# now use socket as usual
|
|
import socket
|
|
addr = socket.getaddrinfo('micropython.org', 80)[0][-1]
|
|
s = socket.socket()
|
|
s.connect(addr)
|
|
s.send(b'GET / HTTP/1.1\r\nHost: micropython.org\r\n\r\n')
|
|
data = s.recv(1000)
|
|
s.close()

class CC3K
|
|
==========
|
|
|
|
This class provides a driver for CC3000 wifi modules. Example usage::
|
|
|
|
import network
|
|
nic = network.CC3K(pyb.SPI(2), pyb.Pin.board.Y5, pyb.Pin.board.Y4, pyb.Pin.board.Y3)
|
|
nic.connect('your-ssid', 'your-password')
|
|
while not nic.isconnected():
|
|
pyb.delay(50)
|
|
print(nic.ifconfig())
|
|
|
|
# now use socket as usual
|
|
...
|
|
|
|
For this example to work the CC3000 module must have the following connections:
|
|
|
|
- MOSI connected to Y8
|
|
- MISO connected to Y7
|
|
- CLK connected to Y6
|
|
- CS connected to Y5
|
|
- VBEN connected to Y4
|
|
- IRQ connected to Y3
|
|
|
|
It is possible to use other SPI busses and other pins for CS, VBEN and IRQ.
|
|
|
|
Constructors

|
|
|
|
.. class:: CC3K(spi, pin_cs, pin_en, pin_irq)
|
|
|
|
Create a CC3K driver object, initialise the CC3000 module using the given SPI bus
|
|
and pins, and return the CC3K object.
|
|
|
|
Arguments are:
|
|
|
|
- ``spi`` is an :ref:`SPI object <pyb.SPI>` which is the SPI bus that the CC3000 is
|
|
connected to (the MOSI, MISO and CLK pins).
|
|
- ``pin_cs`` is a :ref:`Pin object <pyb.Pin>` which is connected to the CC3000 CS pin.
|
|
- ``pin_en`` is a :ref:`Pin object <pyb.Pin>` which is connected to the CC3000 VBEN pin.
|
|
- ``pin_irq`` is a :ref:`Pin object <pyb.Pin>` which is connected to the CC3000 IRQ pin.
|
|
|
|
All of these objects will be initialised by the driver, so there is no need to
|
|
initialise them yourself. For example, you can use::
|
|
|
|
nic = network.CC3K(pyb.SPI(2), pyb.Pin.board.Y5, pyb.Pin.board.Y4, pyb.Pin.board.Y3)
|

Methods
|
|
-------
|
|
|
|
.. method:: cc3k.connect(ssid, key=None, \*, security=WPA2, bssid=None)
|
|
|
|
Connect to a wifi access point using the given SSID, and other security
|
|
parameters.
|
|
|
|
.. method:: cc3k.disconnect()
|
|
|
|
Disconnect from the wifi access point.
|
|
|
|
.. method:: cc3k.isconnected()
|
|
|
|
Returns True if connected to a wifi access point and has a valid IP address,
|
|
False otherwise.
|
|
|
|
.. method:: cc3k.ifconfig()
|
|
|
|
Returns a 7-tuple with (ip, subnet mask, gateway, DNS server, DHCP server,
|
|
MAC address, SSID).
|
|
|
|
.. method:: cc3k.patch_version()
|
|
|
|
Return the version of the patch program (firmware) on the CC3000.
|
|
|
|
.. method:: cc3k.patch_program('pgm')
|
|
|
|
Upload the current firmware to the CC3000. You must pass 'pgm' as the first
|
|
argument in order for the upload to proceed.
|
|
|

class WIZNET5K
|
|
==============
|
|
|
|
This class allows you to control WIZnet5x00 Ethernet adaptors based on
|
|
the W5200 and W5500 chipsets (only W5200 tested).
|
|
|
|
Example usage::
|
|
|
|
import network
|
|
nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
|
|
print(nic.ifconfig())
|
|
|
|
# now use socket as usual
|
|
...
|
|
|
|
For this example to work the WIZnet5x00 module must have the following connections:
|
|
|
|
- MOSI connected to X8
|
|
- MISO connected to X7
|
|
- SCLK connected to X6
|
|
- nSS connected to X5
|
|
- nRESET connected to X4
|
|
|
|
It is possible to use other SPI busses and other pins for nSS and nRESET.
|
|
|
|
Constructors
|
|
------------
|
|
|
|
.. class:: WIZNET5K(spi, pin_cs, pin_rst)
|
|
|
|
Create a WIZNET5K driver object, initialise the WIZnet5x00 module using the given
|
|
SPI bus and pins, and return the WIZNET5K object.
|
|
|
|
Arguments are:
|
|
|
|
- ``spi`` is an :ref:`SPI object <pyb.SPI>` which is the SPI bus that the WIZnet5x00 is
|
|
connected to (the MOSI, MISO and SCLK pins).
|
|
- ``pin_cs`` is a :ref:`Pin object <pyb.Pin>` which is connected to the WIZnet5x00 nSS pin.
|
|
- ``pin_rst`` is a :ref:`Pin object <pyb.Pin>` which is connected to the WIZnet5x00 nRESET pin.
|
|
|
|
All of these objects will be initialised by the driver, so there is no need to
|
|
initialise them yourself. For example, you can use::
|
|
|
|
nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
|
|

|
|
|
|
Get/set IP address, subnet mask, gateway and DNS.
|
|
|
|
When called with no arguments, this method returns a 4-tuple with the above information.
|
|
|
|
To set the above values, pass a 4-tuple with the required information. For example::
|
|
