class WIZNET5K -- control WIZnet5x00 Ethernet modules
|
|
=====================================================
|
|
|
|
This class allows you to control WIZnet5x00 Ethernet adaptors based on
|
|
the W5200 and W5500 chipsets. The particular chipset that is supported
|
|
by the firmware is selected at compile-time via the MICROPY_PY_NETWORK_WIZNET5K
|
|
option.
|
|
|
|
Example usage::
|
|
|
|
import network
|
|
nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
|
|
print(nic.ipconfig("addr4"))
|
|
|
|
# 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 buses 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)
|

Methods
|
|
-------
|
|
|
|
This class implements most methods from `AbstractNIC <AbstractNIC>`, which are documented there. Additional methods are:
|
|
|
|
.. method:: WIZNET5K.regs()
|
|
|
|
Dump the WIZnet5x00 registers. Useful for debugging.
