Damien George 683df1c8d5 drivers/onewire: Enable pull-up when init'ing the 1-wire pin.
A previous version of the 1-wire driver (which was recently replaced by the
current one) had this behaviour and it allows to create a 1-wire bus
without any external pull-up resistors.

Damien George a065d78675 drivers/onewire: Move onewire.py, ds18x20.py from esp8266 to drivers.
These drivers can now be used by any port (so long as that port has the
_onewire driver from extmod/modonewire.c).

These drivers replace the existing 1-wire and DS18X20 drivers in the
drivers/onewire directory.  The existing ones were pyboard-specific and
not very efficient nor minimal (although the 1-wire driver was written in
pure Python it only worked at large enough CPU frequency).

This commit brings backwards incompatible API changes to the existing
1-wire drivers.  User code should be converted to use the new drivers, or
check out the old version of the code and keep a local copy (it should
continue to work unchanged).

Damien George d7310fabc2 drivers/nrf24l01: Update to work on newer ports, using machine, utime.
Changes made are:
- Use the time module in place of the pyb module for delays.
- Use spi.read/spi.write instead of spi.send/spi.receive.
- Drop some non-portable parameters to spi and pin initialization.

Thanks to @deshipu for the original patch.

Paul Sokolovsky d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.

Dave Hylands 3c84197f17 drivers/onewire: Enable pull up on data pin.
The driver seems to be be enabling the pullup resistor in most places, but
not this one. Making this one little change allows onewire devices to be
used with no external pullup resistor.

Damien George 571e6f26db py: Specialise builtin funcs to use separate type for fixed arg count.
Builtin functions with a fixed number of arguments (0, 1, 2 or 3) are
quite common.  Before this patch the wrapper for such a function cost
3 machine words.  After this patch it only takes 2, which can reduce the
code size by quite a bit (and pays off even more, the more functions are
added).  It also makes function dispatch slightly more efficient in CPU
usage, and furthermore reduces stack usage for these cases.  On x86 and
Thumb archs the dispatch functions are now tail-call optimised by the
compiler.

The bare-arm port has its code size increase by 76 bytes, but stmhal drops
by 904 bytes.  Stack usage by these builtin functions is decreased by 48
bytes on Thumb2 archs.

Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Radomir Dopieralski ab8a5d5199 drivers/display/ssd1306: Add width arg and support 64px wide displays.
In particular, the WeMOS D1 Mini board comes with a shield that has a
64x48 OLED display. This patch makes it display properly, with the upper
left pixel being at (0, 0) and not (32, 0).

I tried to do this with the configuration commands, but there doesn't
seem to be a command that would set the column offset (there is one for
the line offset, though).
