More size_t usage 2019-08-27 12:49:46 -07:00
Scott Shawcroft 5662b5813e
Use size_t and document buffers can be the same. 2019-08-23 12:13:11 -07:00
Scott Shawcroft 82d436d05e
Add writeto_then_readfrom to I2C API. Deprecate stop kwarg.
writeto_then_readfrom has been added to do a write -> no stop ->
repeated start -> read sequence. This is done to match the
capabilities of Blinka on Linux.

Code that uses stop=False will not work correctly on Blinka.
To fix, if stop=False then use writeto_then_readfrom otherwise use
writeto then readfrom_into.

First step in #2082

Scott Shawcroft 714521a4c7 shared-bindings: Update docs to remove with statements from examples but add more detail to the design guide about their use. 2017-06-07 14:39:12 -07:00
Scott Shawcroft 939c0045db Switch to a shared piece of code to compute start and length of a
buffer from start, end and length. The old code miscomputed length
leading to writing and reading from memory past the end of the buffer.
Consolidating the code should make it easier to get right everywhere.

Scott Shawcroft 4a4f29b8f9 atmel-samd: Rework status LED implementation
* Track status pin use by user code separately so it can take over the pins and then give them back.
* Switch to hardware SPI for APA102 on Gemma and Trinket.
* Merge microcontroller/types.h into microcontroller/Pin.h to better match approach going forwards.

Scott Shawcroft 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.

Scott Shawcroft 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.

Scott Shawcroft 4aaa0ea008 shared-bindings: Do a pass on the docs and make sure keyword only arguments make sense and are documented correctly. Fixes #109 2017-03-07 12:58:57 +01:00
Scott Shawcroft 7ecbc3a148 shared-bindings: Fix two more try_locks. Copy and paste failed me. 2017-02-28 12:31:27 +01:00
Scott Shawcroft 12fa5b3a66 Switch exception throwing to mp_raise helpers. It saves a little code space each time to share the call. 2017-02-24 15:13:07 +01:00
Scott Shawcroft 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

Scott Shawcroft e9659e61f8 Switch enum-like attributes to all caps and add print support for them. Make room for this functionality by adding a shared __enter__ function object. #76 2017-02-19 16:11:33 +01:00
Scott Shawcroft 26229efe78 Add try_lock and unlock to I2C and SPI classes to make sure things
are shared well between threads and underlying MicroPython (SPI Flash
for example.)

It is recommended to use the bus device classes to manage the locks
and other transaction state.

Scott Shawcroft ccbb5e84f9 This introduces an alternative hardware API called nativeio structured around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware.
Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/

It differs from upstream's machine in the following ways:

* Python API is identical across ports due to code structure. (Lives in shared-bindings)
* Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC).
* Documentation lives with code making it easy to ensure they match.
* Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut).
* All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware.
* All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.
