docs: Bump version to 1.7.

When lwIP creates a incoming connection socket of a listen socket, it
sets its recv callback to one which discards incoming data. We set
proper callback only in accept() call, when we allocate Python-level
socket where we can queue incoming data. So, in lwIP accept callback
be sure to set recv callback to one which tells lwIP to not discard
incoming data.

+External dependencies
+---------------------
+
+Building Unix version requires some dependencies installed. For
+Debian/Ubuntu/Mint derivative Linux distros, install `build-essential`
+(includes toolchain and make), `libffi-dev`, and `pkg-config` packages.
+
+Other dependencies can be built together with MicroPython. Oftentimes,
+you need to do this to enable extra features or capabilities. To build
+these additional dependencies, first fetch git submodules for them:
+
+    $ git submodule update --init
+
+Use this same command to get the latest versions of dependencies, as
+they are updated from time to time. After that, in `unix/` dir, execute:
+
+    $ make deplibs
+
+This will build all available dependencies (regardless whether they
+are used or not). If you intend to build MicroPython with additional
+options (like cross-compiling), the same set of options should be passed
+to `make deplibs`. To actually enabled use of dependencies, edit
+`unix/mpconfigport.mk` file, which has inline descriptions of the options.
+For example, to build SSL module (required for `upip` tool described above),
+set `MICROPY_PY_USSL` to 1.
+
+In `unix/mpconfigport.mk`, you can also disable some dependencies enabled
+by default, like FFI support, which requires libffi development files to
+be installed.

+MicroPython Documentation
+=========================
+
+The MicroPython documentation can be found at:
+http://docs.micropython.org/en/latest/
+
+The documentation you see there is generated from the files in the docs tree:
+https://github.com/micropython/micropython/tree/master/docs
+
+Building the documentation locally
+----------------------------------
+
+If you're making changes to the documentation, you may want to build the
+documentation locally so that you can preview your changes.
+
+Install Sphinx, and optionally (for the RTD-styling), sphinx_rtd_theme,
+preferably in a virtualenv:
+
+     pip install sphinx
+     pip install sphinx_rtd_theme
+
+In `micropython/docs`, build the docs:
+
+    make MICROPY_PORT=<port_name> BUILDDIR=build/<port_name> html
+
+Where `<port_name>` can be `unix`, `pyboard`, `wipy` or `esp8266`.
+
+You'll find the index page at `micropython/docs/build/<port_name>/html/index.html`.

+The Adafruit Feather HUZZAH board (image attribution: Adafruit).
+
+General board control
+---------------------
+
+The MicroPython REPL is on UART0 (GPIO1=TX, GPIO3=RX) at baudrate 115200.
+Tab-completion is useful to find out what methods an object has.
+Paste mode (ctrl-E) is useful to paste a large slab of Python code into
+the REPL.
+
+The ``machine`` module::
+
+    import machine
+
+    machine.freq()          # get the current frequency of the CPU
+    machine.freq(160000000) # set the CPU frequency to 160 MHz
+
+The ``esp`` module::
+
+    import esp
+
+    esp.osdebug(None)       # turn off vendor O/S debugging messages
+    esp.osdebug(0)          # redirect vendor O/S debugging messages to UART(0)
+
+Networking
+----------
+
+The ``network`` module::
+
+    import network
+
+    wlan = network.WLAN(network.STA_IF) # create station interface
+    wlan.active(True)       # activate the interface
+    wlan.scan()             # scan for access points
+    wlan.isconnected()      # check if the station is connected to an AP
+    wlan.connect('essid', 'password') # connect to an AP
+    wlan.mac()              # get the interface's MAC adddress
+    wlan.ifconfig()         # get the interface's IP/netmask/gw/DNS addresses
+
+    ap = network.WLAN(network.AP_IF) # create access-point interface
+    ap.active(True)         # activate the interface
+    ap.config(essid='ESP-AP') # set the ESSID of the access point
+
+A useful function for connecting to your local WiFi network is::
+
+    def do_connect():
+        import network
+        wlan = network.WLAN(network.STA_IF)
+        wlan.active(True)
+        if not wlan.isconnected():
+            print('connecting to network...')
+            wlan.connect('essid', 'password')
+            while not wlan.isconnected():
+                pass
+        print('network config:', wlan.ifconfig())
+
+Once the network is established the ``socket`` module can be used
+to create and use TCP/UDP sockets as usual.
+
+Delay and timing
+----------------
+
+Use the ``time`` module::
+
+    import time
+
+    time.sleep(1)           # sleep for 1 second
+    time.sleep_ms(500)      # sleep for 500 milliseconds
+    time.sleep_us(10)       # sleep for 10 microseconds
+    start = time.ticks_ms() # get millisecond counter
+    delta = time.ticks_diff(start, time.ticks_ms()) # compute time difference
+
+Timers
+------
+
+Virtual (RTOS-based) timers are supported. Use the ``machine.Timer`` class
+with timer ID of -1::
+
+    from machine import Timer
+
+    tim = Timer(-1)
+    tim.init(period=5000, mode=Timer.ONE_SHOT, callback=lambda t:print(1))
+    tim.init(period=2000, mode=Timer.PERIODIC, callback=lambda t:print(2))
+
+The period is in milliseconds.
+
+Pins and GPIO
+-------------
+
+Use the ``machine.Pin`` class::
+
+    from machine import Pin
+
+    p0 = Pin(0, Pin.OUT)    # create output pin on GPIO0
+    p0.high()               # set pin to high
+    p0.low()                # set pin to low
+    p0.value(1)             # set pin to high
+
+    p2 = Pin(2, Pin.IN)     # create input pin on GPIO2
+    print(p2.value())       # get value, 0 or 1
+
+    p4 = Pin(4, Pin.IN, Pin.PULL_UP) # enable internal pull-up resistor
+    p5 = Pin(5, Pin.OUT, value=1) # set pin high on creation
+
+Available pins are: 0, 1, 2, 3, 4, 5, 12, 13, 14, 15, 16, which correspond
+to the actual GPIO pin numbers of ESP8266 chip. Note that many end-user
+boards use their own adhoc pin numbering (marked e.g. D0, D1, ...). As
+MicroPython supports different boards and modules, physical pin numbering
+was chosen as the lowest common denominator. For mapping between board
+logical pins and physical chip pins, consult your board documentation.
+
+Note that Pin(1) and Pin(3) are REPL UART TX and RX respectively.
+Also note that Pin(16) is a special pin (used for wakeup from deepsleep
+mode) and may be not available for use with higher-level classes like
+``Neopixel``.
+
+PWM (pulse width modulation)
+----------------------------
+
+PWM can be enabled on all pins except Pin(16).  There is a single frequency
+for all channels, with range between 1 and 1000 (measured in Hz).  The duty
+cycle is between 0 and 1023 inclusive.
+
+Use the ``machine.PWM`` class::
+
+    from machine import Pin, PWM
+
+    pwm0 = PWM(Pin(0))      # create PWM object from a pin
+    pwm0.freq()             # get current frequency
+    pwm0.freq(1000)         # set frequency
+    pwm0.duty()             # get current duty cycle
+    pwm0.duty(200)          # set duty cycle
+    pwm0.deinit()           # turn off PWM on the pin
+
+    pwm2 = PWM(Pin(2), freq=500, duty=512) # create and configure in one go
+
+ADC (analog to digital conversion)
+----------------------------------
+
+ADC is available on a dedicated pin.
+Note that input voltages on the ADC pin must be between 0v and 1.0v.
+
+Use the ``machine.ADC`` class::
+
+    from machine import ADC
+
+    adc = ADC(0)            # create ADC object on ADC pin
+    adc.read()              # read value, 0-1024
+
+SPI bus
+-------
+
+The SPI driver is implemented in software and works on all pins::
+
+    from machine import Pin, SPI
+
+    # construct an SPI bus on the given pins
+    # polarity is the idle state of SCK
+    # phase=0 means sample on the first edge of SCK, phase=1 means the second
+    spi = SPI(baudrate=100000, polarity=1, phase=0, sck=Pin(0), mosi=Pin(2), miso=Pin(4))
+
+    spi.init(baudrate=200000) # set the baudrate
+
+    spi.read(10)            # read 10 bytes on MISO
+    spi.read(10, 0xff)      # read 10 bytes while outputing 0xff on MOSI
+
+    buf = bytearray(50)     # create a buffer
+    spi.readinto(buf)       # read into the given buffer (reads 50 bytes in this case)
+    spi.readinto(buf, 0xff) # read into the given buffer and output 0xff on MOSI
+
+    spi.write(b'12345')     # write 5 bytes on MOSI
+
+    buf = bytearray(4)      # create a buffer
+    spi.write_readinto(b'1234', buf) # write to MOSI and read from MISO into the buffer
+    spi.write_readinto(buf, buf) # write buf to MOSI and read MISO back into buf
+
+I2C bus
+-------
+
+The I2C driver is implemented in software and works on all pins::
+
+    from machine import Pin, I2C
+
+    # construct an I2C bus
+    i2c = I2C(scl=Pin(5), sda=Pin(4), freq=100000)
+
+    i2c.readfrom(0x3a, 4)   # read 4 bytes from slave device with address 0x3a
+    i2c.writeto(0x3a, '12') # write '12' to slave device with address 0x3a
+
+    buf = bytearray(10)     # create a buffer with 10 bytes
+    i2c.writeto(0x3a, buf)  # write the given buffer to the slave
+
+    i2c.readfrom(0x3a, 4, stop=False) # don't send a stop bit after reading
+    i2c.writeto(0x3a, buf, stop=False) # don't send a stop bit after writing
+
+OneWire driver
+--------------
+
+The OneWire driver is implemented in software and works on all pins::
+
+    from machine import Pin
+    import onewire
+
+    ow = onewire.OneWire(Pin(12)) # create a OneWire bus on GPIO12
+    ow.scan()               # return a list of devices on the bus
+    ow.reset()              # reset the bus
+    ow.read_byte()          # read a byte
+    ow.read_bytes(5)        # read 5 bytes
+    ow.write_byte(0x12)     # write a byte on the bus
+    ow.write_bytes('123')   # write bytes on the bus
+    ow.select_rom(b'12345678') # select a specific device by its ROM code
+
+There is a specific driver for DS18B20 devices::
+
+    import time
+    ds = onewire.DS18B20(ow)
+    roms = ds.scan()
+    ds.start_measure()
+    time.sleep_ms(750)
+    for rom in roms:
+        print(ds.get_temp(rom))
+
+Be sure to put a 4.7k pull-up resistor on the data line.
+
+NeoPixel driver
+---------------
+
+Use the ``neopixel`` module::
+
+    from machine import Pin
+    from neopixel import NeoPixel
+
+    pin = Pin(0, Pin.OUT)   # set GPIO0 to output to drive NeoPixels
+    np = NeoPixel(pin, 8)   # create NeoPixel driver on GPIO0 for 8 pixels
+    np[0] = (255, 255, 255) # set the first pixel to white
+    np.write()              # write data to all pixels
+    r, g, b = np[0]         # get first pixel colour
+
+    import neopixel
+    neopixel.demo(np)       # run a demo
+
+For low-level driving of a NeoPixel::
+

+.. _machine.Pin:
+
+class Pin -- control I/O pins
+=============================
+
+A pin is the basic object to control I/O pins.  It has methods to set
+the mode of the pin (input, output, etc) and methods to get and set the
+digital logic level. For analog control of a pin, see the ADC class.
+
+Usage Model:
+
+.. only:: port_wipy
+
+    Board pins are identified by their string id::
+
+        from machine import Pin
+        g = machine.Pin('GP9', mode=Pin.OUT, pull=None, drive=Pin.MED_POWER, alt=-1)
+
+    You can also configure the Pin to generate interrupts. For instance::
+
+        from machine import Pin
+
+        def pincb(pin):
+            print(pin.id())
+
+        pin_int = Pin('GP10', mode=Pin.IN, pull=Pin.PULL_DOWN)
+        pin_int.irq(trigger=Pin.IRQ_RISING, handler=pincb)
+        # the callback can be triggered manually
+        pin_int.irq()()
+        # to disable the callback
+        pin_int.irq().disable()
+
+    Now every time a falling edge is seen on the gpio pin, the callback will be
+    executed. Caution: mechanical push buttons have "bounce" and pushing or
+    releasing a switch will often generate multiple edges.
+    See: http://www.eng.utah.edu/~cs5780/debouncing.pdf for a detailed
+    explanation, along with various techniques for debouncing.
+
+    All pin objects go through the pin mapper to come up with one of the
+    gpio pins.
+
+Constructors

+class Timer -- control internal timers
+======================================
+
+.. only:: port_wipy
+
+    Timers can be used for a great variety of tasks, calling a function periodically,
+    counting events, and generating a PWM signal are among the most common use cases.
+    Each timer consists of two 16-bit channels and this channels can be tied together to
+    form one 32-bit timer. The operating mode needs to be configured per timer, but then
+    the period (or the frequency) can be independently configured on each channel. 
+    By using the callback method, the timer event can call a Python function.
+
+    Example usage to toggle an LED at a fixed frequency::
+
+        from machine import Timer
+        from machine import Pin
+        led = Pin('GP16', mode=Pin.OUT)                  # enable GP16 as output to drive the LED
+        tim = Timer(3)                                   # create a timer object using timer 3
+        tim.init(mode=Timer.PERIODIC)                    # initialize it in periodic mode
+        tim_ch = tim.channel(Timer.A, freq=5)            # configure channel A at a frequency of 5Hz
+        tim_ch.irq(handler=lambda t:led.toggle(), trigger=Timer.TIMEOUT)        # toggle a LED on every cycle of the timer
+
+    Example using named function for the callback::
+
+        from machine import Timer
+        from machine import Pin
+        tim = Timer(1, mode=Timer.PERIODIC, width=32)
+        tim_a = tim.channel(Timer.A | Timer.B, freq=1)   # 1 Hz frequency requires a 32 bit timer
+
+        led = Pin('GP16', mode=Pin.OUT) # enable GP16 as output to drive the LED
+
+        def tick(timer):                # we will receive the timer object when being called
+            global led
+            led.toggle()                # toggle the LED
+
+        tim_a.irq(handler=tick, trigger=Timer.TIMEOUT)         # create the interrupt
+
+    Further examples::

+        tim1_ch = tim1.channel(Timer.A, freq=10, polarity=Timer.POSITIVE)  # start the event counter with a frequency of 10Hz and triggered by positive edges
+        tim2_ch = tim2.channel(Timer.B, freq=10000, duty_cycle=5000)       # start the PWM on channel B with a 50% duty cycle
+        tim2_ch.freq(20)                                                   # set the frequency (can also get)

+       
+         - ``mode`` can be one of:
+         
+           - ``Timer.ONE_SHOT`` - The timer runs once until the configured

+             frequency of the channel.
+           - ``Timer.PWM``      - Output a PWM signal on a pin.
+
+         - ``width`` must be either 16 or 32 (bits). For really low frequencies < 5Hz
+           (or large periods), 32-bit timers should be used. 32-bit mode is only available
+           for ``ONE_SHOT`` AND ``PERIODIC`` modes.

+   Stops the timer, and disables the timer peripheral.
+

+
+    .. method:: timer.channel(channel, \**, freq, period, polarity=Timer.POSITIVE, duty_cycle=0)
+    
+       If only a channel identifier passed, then a previously initialized channel
+       object is returned (or ``None`` if there is no previous channel).
+
+       Othwerwise, a TimerChannel object is initialized and returned.
+       
+       The operating mode is is the one configured to the Timer object that was used to
+       create the channel.
+
+       - ``channel`` if the width of the timer is 16-bit, then must be either ``TIMER.A``, ``TIMER.B``. 
+         If the width is 32-bit then it **must be** ``TIMER.A | TIMER.B``.
+
+       Keyword only arguments:
+
+         - ``freq`` sets the frequency in Hz.
+         - ``period`` sets the period in microseconds.
+
+         .. note::
+
+            Either ``freq`` or ``period`` must be given, never both.
+
+         - ``polarity`` this is applicable for ``PWM``, and defines the polarity of the duty cycle
+         - ``duty_cycle`` only applicable to ``PWM``. It's a percentage (0.00-100.00). Since the WiPy
+           doesn't support floating point numbers the duty cycle must be specified in the range 0-10000,
+           where 10000 would represent 100.00, 5050 represents 50.50, and so on.
+
+       .. note::
+
+          When the channel is in PWM mode, the corresponding pin is assigned automatically, therefore
+          there's no need to assign the alternate function of the pin via the ``Pin`` class. The pins which
+          support PWM functionality are the following:
+
+          - ``GP24`` on Timer 0 channel A.
+          - ``GP25`` on Timer 1 channel A.
+          - ``GP9``  on Timer 2 channel B.
+          - ``GP10`` on Timer 3 channel A.

+              with the configured frequency or period.
+            - If mode is ``Timer.ONE_SHOT`` the callback is executed once when
+              the configured timer expires.
+            - If mode is ``Timer.PWM`` the callback is executed when reaching the duty
+              cycle value.
+
+        The accepted params are:
+
+            - ``priority`` level of the interrupt. Can take values in the range 1-7.
+              Higher values represent higher priorities.
+            - ``handler`` is an optional function to be called when the interrupt is triggered.
+            - ``trigger`` must be ``Timer.TIMEOUT`` when the operating mode is either ``Timer.PERIODIC`` or
+              ``Timer.ONE_SHOT``. In the case that mode is ``Timer.PWM`` then trigger must be equal to
+              ``Timer.MATCH``.
+
+        Returns a callback object.
+
+.. only:: port_wipy

+       Get or set the timer channel period (in microseconds).
+
+    .. method:: timerchannel.duty_cycle([value])

+is a character (not to be confused with a string character) which can be 8 or 9
+bits wide.
+
+UART objects can be created and initialised using::
+
+    from machine import UART
+
+    uart = UART(1, 9600)                         # init with given baudrate
+    uart.init(9600, bits=8, parity=None, stop=1) # init with given parameters
+
+.. only:: port_machineoard
+
+    Bits can be 7, 8 or 9.  Parity can be None, 0 (even) or 1 (odd).  Stop can be 1 or 2.
+    
+    *Note:* with parity=None, only 8 and 9 bits are supported.  With parity enabled,
+    only 7 and 8 bits are supported.
+
+.. only:: port_wipy
+
+    Bits can be 5, 6, 7, 8.  Parity can be ``None``, ``UART.EVEN`` or ``UART.ODD``.  Stop can be 1 or 2.
+
+
+A UART object acts like a stream object and reading and writing is done
+using the standard stream methods::
+
+    uart.read(10)       # read 10 characters, returns a bytes object
+    uart.readall()      # read all available characters
+    uart.readline()     # read a line
+    uart.readinto(buf)  # read and store into the given buffer
+    uart.write('abc')   # write the 3 characters
+
+.. only:: port_machineoard
+
+    Individual characters can be read/written using::
+
+        uart.readchar()     # read 1 character and returns it as an integer
+        uart.writechar(42)  # write 1 character
+
+    To check if there is anything to be read, use::
+
+        uart.any()               # returns True if any characters waiting
+
+    *Note:* The stream functions ``read``, ``write``, etc. are new in MicroPython v1.3.4.
+    Earlier versions use ``uart.send`` and ``uart.recv``.
+
+.. only:: port_wipy
+
+    To check if there is anything to be read, use::
+
+        uart.any()               # returns the number of characters available for reading
+
+Constructors
+------------
+
+.. only:: port_wipy
+
+    .. class:: machine.UART(bus, ...)
+    
+       Construct a UART object on the given bus.  ``bus`` can be 0 or 1.
+       If the bus is not given, the default one will be selected (0) or the selection
+       will be made based on the given pins.
+
+Methods
+-------
+
+.. only:: port_wipy
+
+    .. method:: uart.init(baudrate=9600, bits=8, parity=None, stop=1, \*, pins=(TX, RX, RTS, CTS))
+    
+       Initialise the UART bus with the given parameters:
+    
+         - ``baudrate`` is the clock rate.
+         - ``bits`` is the number of bits per character, 7, 8 or 9.
+         - ``parity`` is the parity, ``None``, ``UART.EVEN`` or ``UART.ODD``.
+         - ``stop`` is the number of stop bits, 1 or 2.
+         - ``pins`` is a 4 or 2 item list indicating the TX, RX, RTS and CTS pins (in that order).
+           Any of the pins can be None if one wants the UART to operate with limited functionality.
+           If the RTS pin is given the the RX pin must be given as well. The same applies to CTS. 
+           When no pins are given, then the default set of TX and RX pins is taken, and hardware 
+           flow control will be disabled. If pins=None, no pin assignment will be made.
+
+.. method:: uart.deinit()
+
+   Turn off the UART bus.
+
+.. method:: uart.any()
+
+   Return the number of characters available for reading.
+
+.. method:: uart.read([nbytes])
+
+   Read characters.  If ``nbytes`` is specified then read at most that many bytes.
+
+   Return value: a bytes object containing the bytes read in.  Returns ``None``
+   on timeout.
+
+.. method:: uart.readall()
+
+   Read as much data as possible.
+
+   Return value: a bytes object or ``None`` on timeout.
+
+.. method:: uart.readinto(buf[, nbytes])
+
+   Read bytes into the ``buf``.  If ``nbytes`` is specified then read at most
+   that many bytes.  Otherwise, read at most ``len(buf)`` bytes.
+
+   Return value: number of bytes read and stored into ``buf`` or ``None`` on
+   timeout.
+
+.. method:: uart.readline()
+
+   Read a line, ending in a newline character.
+
+   Return value: the line read or ``None`` on timeout.
+
+.. method:: uart.write(buf)
+
+   Write the buffer of bytes to the bus.
+
+   Return value: number of bytes written or ``None`` on timeout.
+
+.. method:: uart.sendbreak()
+
+   Send a break condition on the bus.  This drives the bus low for a duration
+   of 13 bits.
+   Return value: ``None``.
+
+.. only:: port_wipy
+
+    .. method:: uart.irq(trigger, priority=1, handler=None, wake=machine.IDLE)
+
+       Create a callback to be triggered when data is received on the UART.
+
+           - ``trigger`` can only be ``UART.RX_ANY``
+           - ``priority`` level of the interrupt. Can take values in the range 1-7.
+             Higher values represent higher priorities.
+           - ``handler`` an optional function to be called when new characters arrive.
+           - ``wake`` can only be ``machine.IDLE``.
+
+       .. note::
+
+          The handler will be called whenever any of the following two conditions are met:
+
+              - 8 new characters have been received.
+              - At least 1 new character is waiting in the Rx buffer and the Rx line has been
+                silent for the duration of 1 complete frame.
+
+          This means that when the handler function is called there will be between 1 to 8 
+          characters waiting.
+
+       Returns an irq object.

 class WDT -- watchdog timer
 ===========================
 
 The WDT is used to restart the system when the application crashes and ends
 up into a non recoverable state. Once started it cannot be stopped or
-reconfigured in any way. After enabling, the application must "kick" the
+reconfigured in any way. After enabling, the application must "feed" the
 watchdog periodically to prevent it from expiring and resetting the system.
 
 Example usage::
 
-    wdt = pyb.WDT(timeout=2000) # enable with a timeout of 2s

+:mod:`machine` --- functions related to the board
+=================================================
+
+.. module:: machine
+   :synopsis: functions related to the board
+
+The ``machine`` module contains specific functions related to the board.
+
+Reset related functions
+-----------------------
+
+.. function:: reset()
+
+   Resets the device in a manner similar to pushing the external RESET
+   button.
+
+.. function:: reset_cause()
+
+   Get the reset cause. See :ref:`constants <machine_constants>` for the possible return values.
+
+Interrupt related functions
+---------------------------
+
+.. function:: disable_irq()
+
+   Disable interrupt requests.
+   Returns the previous IRQ state: ``False``/``True`` for disabled/enabled IRQs
+   respectively.  This return value can be passed to enable_irq to restore
+   the IRQ to its original state.
+
+.. function:: enable_irq(state=True)
+
+   Enable interrupt requests.
+   If ``state`` is ``True`` (the default value) then IRQs are enabled.
+   If ``state`` is ``False`` then IRQs are disabled.  The most common use of
+   this function is to pass it the value returned by ``disable_irq`` to
+   exit a critical section.
+
+Power related functions
+-----------------------
+
+.. function:: freq()
+
+   Returns a tuple of clock frequencies: ``(sysclk,)``
+   These correspond to:
+
+      - sysclk: frequency of the CPU
+
+.. function:: idle()
+
+   Gates the clock to the CPU, useful to reduce power consumption at any time during
+   short or long periods. Peripherals continue working and execution resumes as soon
+   as any interrupt is triggered (including the systick which has a period of 1ms).
+   Current consumption is reduced to ~12mA (in WLAN STA mode)
+
+.. function:: sleep()
+
+   Stops the CPU and disables all peripherals except for WLAN. Execution is resumed from
+   the point where the sleep was requested. Wake sources are ``Pin``, ``RTC`` and ``WLAN``.
+   Current consumption is reduced to 950uA (in WLAN STA mode).
+
+.. function:: deepsleep()
+
+   Stops the CPU and all peripherals including WLAN. Execution is resumed from main, just
+   as with a reset. The reset cause can be checked to know that we are coming from
+   from ``machine.DEEPSLEEP``. Wake sources are ``Pin`` and ``RTC``. Current consumption 
+   is reduced to ~5uA.
+
+.. function:: wake_reason()
+
+   Get the wake reason. See :ref:`constants <machine_constants>` for the possible return values.
+
+Miscellaneous functions
+-----------------------
+
+.. function:: main(filename)
+
+   Set the filename of the main script to run after boot.py is finished.  If
+   this function is not called then the default file main.py will be executed.
+
+   It only makes sense to call this function from within boot.py.
+
+.. function:: rng()
+
+   Return a 24-bit software generated random number.
+
+.. function:: unique_id()
+
+   Returns a string of 6 bytes (48 bits), which is the unique ID of the MCU.
+   This also corresponds to the network ``MAC address``.
