wiznet – Support for WizNet hardware, including the WizNet 5500 Ethernet adaptor.

Warning

This module is disabled in 6.x and will removed in 7.x. Please use networking libraries instead.

class wiznet.WIZNET5K(spi: busio.SPI, cs: microcontroller.Pin, rst: microcontroller.Pin, dhcp: bool = True)

Wrapper for Wiznet 5500 Ethernet interface

Create a new WIZNET5500 interface using the specified pins

Parameters

  • spi (SPI) – spi bus to use

  • cs (Pin) – pin to use for Chip Select

  • rst (Pin) – pin to use for Reset (optional)

  • dhcp (bool) – boolean flag, whether to start DHCP automatically (optional, keyword only, default True)

  • The reset pin is optional: if supplied it is used to reset the wiznet board before initialization.

  • The SPI bus will be initialized appropriately by this library.

  • At present, the WIZNET5K object is a singleton, so only one WizNet interface is supported at a time.

connected :bool

(boolean, readonly) is this device physically connected?

dhcp :bool

(boolean, readwrite) is DHCP active on this device?

  • set to True to activate DHCP, False to turn it off

ifconfig(self, params: Optional[Tuple[str, str, str, str]] = None) → Optional[Tuple[str, str, str, str]]

Called without parameters, returns a tuple of (ip_address, subnet_mask, gateway_address, dns_server)

Or can be called with the same tuple to set those parameters. Setting ifconfig parameters turns DHCP off, if it was on.
