1e8fc15a41 atmel-samd: Fix PulseIn duration math to handle case when current us time is after the last one but more than a ms has passed. 2017-04-11 16:55:42 -07:00

f28f8ba568 Split up nativeio. 
This was done to allow greatly granularity when deciding what functionality
is built into each board's build. For example, this way pulseio can be
omitted to allow for something else such as touchio.

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.

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

370d1dec88 SPI tweaks for SD Cards: 
* Always init SPI to 250k to start for SD cards.
* Add ability to configure byte written during read.
* Add ability to read and write to portions of buffers like existing I2C API.

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.
