|
|
=========================================
|
|
|
|
|
|
|
|
|
|
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)
|

|
|
|
|
.. method:: CC3K.isconnected()
|
|
|
|
|
|
|
|
|
|
Returns True if connected to a WiFi access point and has a valid IP address,
|
|
|
|
|
False otherwise.
|
|
|
|
|
|
|
