class CC3K – control CC3000 WiFi modules

This class provides a driver for CC3000 WiFi modules. Example usage:: 这个类为CC3000 WiFi模块提供了一个驱动程序。用法:例子:

import network 进口网络 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 # 现在像往常一样使用套接字 …

For this example to work the CC3000 module must have the following connections: 在这个例子中，CC3000模块必须有以下连接:

  • 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. 它是可能使用其他SPI总线和其他针的CS, VBEN和IRQ。

Constructors 构造函数 ————

class network.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. 创建一个CC3K驱动程序对象，使用给定的SPI总线初始化CC3000模块 并返回CC3K对象。

Arguments are: 参数:

  • spi is an SPI object which is the SPI bus that the CC3000 is connected to (the MOSI, MISO and CLK pins).

  • spi is an SPI object CC3000是哪一种SPI总线 连接到(MOSI，味噌和CLK引脚)。

  • pin_cs is a Pin object which is connected to the CC3000 CS pin.

  • pin_cs is a Pin object 连接到CC3000 CS引脚。

  • pin_en is a Pin object which is connected to the CC3000 VBEN pin.

  • pin_en is a Pin object 连接到CC3000 VBEN引脚。

  • pin_irq is a Pin object which is connected to the CC3000 IRQ pin.

  • pin_irq is a Pin object 它连接到CC3000 IRQ引脚。

All of these objects will be initialised by the driver, so there is no need to initialise them yourself. For example, you can use:: 所有这些对象都将被驱动程序初始化，所以没有必要这样做 初始化自己。例如，你可以用:

nic = network.CC3K(pyb.SPI(2), pyb.Pin.board.Y5, pyb.Pin.board.Y4, pyb.Pin.board.Y3)

Methods 方法 ——-

CC3K.connect(ssid, key=None, \*, security=WPA2, bssid=None)

Connect to a WiFi access point using the given SSID, and other security parameters. 使用给定的SSID和其他安全措施连接到WiFi接入点参数。

CC3K.disconnect()

Disconnect from the WiFi access point. 断开WiFi接入点。

CC3K.isconnected()

Returns True if connected to a WiFi access point and has a valid IP address, False otherwise. 如果连接到WiFi接入点并且有一个有效的IP地址，返回True，否则错误。

CC3K.ifconfig()

Returns a 7-tuple with (ip, subnet mask, gateway, DNS server, DHCP server, MAC address, SSID). 返回一个7元组(ip，子网掩码，网关，DNS服务器，DHCP服务器，MAC地址,SSID)。

CC3K.patch_version()

Return the version of the patch program (firmware) on the CC3000. 返回CC3000上补丁程序(固件)的版本。

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. 上传当前固件到CC3000。你必须以第一名通过’pgm’参数，以便继续上载。

Constants 常量 ———
