ff208d7677 Add low-level OneWire support class. 
This class focuses on the timing sensitive parts of the protocol.
Everything else will be done by Python code.

This also establishes that its OK to back a nativeio class with a
bitbang implementation when no hardware acceleration exists. When
it does, then bitbangio should be used to explicitly bitbang a
protocol.

7cb54864aa Add PulseIn support which can be used to measure a series of pulse widths. 
This is useful for infrared input and DHT sensors.

062fac1d43 atmel-samd: Use link time optimization to reduce code size of builds which 
share space with the file system.

"Express" builds with SPI flash crash the compiler for some reason so its
currently disabled for them.

4c05086661 Check that neopixel write is actually given a DigitalInOut. 2017-02-22 20:10:10 +01:00

fc718d9437 ESP8266: Stop supporting 400khz neopixels through old esp module API. 
It still accepts the parameter for backwards compatibility and to
provide a good error when it can't work.

Using the `neopixel_write` module instead is recommended because its
available on all CircuitPython supported ports.

710b5d8aff Two I2C fixes: 
1) Bus error will be thrown on read/write errors with errno set. (Read didn't used to fail at all.)
2) try_lock correctly returns boolean whether lock was grabbed.

Fixes #87

49287e91b1 ESP8266: Rework the execution flow to match the SAMD21. 
* Support code.txt and variants.
* Add wait state for connection indicated by receiving a character.
* Add another wait state on every soft reset to give instruction for
  soft reset rather than entering REPL.

AMPY use remains the same. The wait states can be exited with CTRL-C
just like the REPL.

Fixes #70.
