///
/// The DAC is used to output analog values (a specific voltage) on pin X5 or pin X6.
/// The voltage will be between 0 and 3.3V.
///
/// *This module will undergo changes to the API.*
///
/// Example usage:
///
///     from pyb import DAC
///
///     dac = DAC(1)            # create DAC 1 on pin X5
///     dac.write(128)          # write a value to the DAC (makes X5 1.65V)
///
/// To output a continuous sine-wave:
///
///     import math
///     from pyb import DAC
///
///     # create a buffer containing a sine-wave
///     buf = bytearray(100)
///     for i in range(len(buf)):
///         buf[i] = 128 + int(127 * math.sin(2 * math.pi * i / len(buf)))
///
///     # output the sine-wave at 400Hz

@Import micropython version 1.5.2 into othersrc.

Micropython is a python3 implementation that has been optimised for
micro-controllers and small embedded systems.  It also has a "unix"
port. It has an MIT license.

This is version 1.5.2 of micropython.

	MicroPython implements the entire Python 3.4 syntax (including
	exceptions, "with", "yield from", etc.).  The following core
	datatypes are provided:  str (including basic Unicode
	support), bytes, bytearray, tuple, list, dict, set, frozenset,
	array.array, collections.namedtuple, classes and instances. 
	Builtin modules include sys, time, and struct.  Note that only
	subset of Python 3.4 functionality implemented for the data
	types and modules.

This is the standard micropython source (version v1.5.2), which has been
adapted to use reachover infrastructure. At the present time, libffi
(from pkgsrc) is used. Alternative locations for libffi can be set
using the PKGSRC_PREFIX definition to make.

In the whole scheme of things, micropython is quite small:

	% size bin/micropython
	   text    data     bss     dec     hex filename
	 393495    1624    2208  397327   6100f bin/micropython
	%

and runs much as expected:

	% bin/micropython
	MicroPython v1.5.2 on 2016-01-13; linux version
	Use Ctrl-D to exit, Ctrl-E for paste mode
	>>> print("hello world")
	hello world
