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.

e3f9ee839a Add frequency changing support to PWMOut. 
You can either set it once up front, or set variable_frequency on custruction to
indicate that the frequency must be able to change. This informs whether a timer
can be shared amongst pins.

This also adds persistent clock calibration on atmel-samd. Once the device has
synced its clock frequency over USB it will remember that config value until USB
is used again. This helps ensure the clock frequency is similar on and off USB.

Lastly, this also corrects time.sleep() when on USB by correcting the tick counter.
