sommersoft 44bc1711aa Added Unique ID Functions/Updated Support Matrix (#527)
shared_bindings/index.rst: updated Support Matrix format as discussed in PR #503 & Issue #448.

shared-bindings/microcontroller/Processor.c & .h: added UID lookup functionality for use with all ports. Fixes #462.

sommersoft 36ec29d4e8 Documentation Updates (mcu.delay() and Design Guide) (#481)
/docs/design_guide: added links to firmware build learning guides for SAMD21 & ESP8266. Changes were placed in the "Adding native modules" section, since that seemed to me the best place based on target audience.

Updated documentation for `delay()` which fixes #243.

Scott Shawcroft a91e1cb682 Fix a couple spelling errors. 2017-12-05 16:04:47 -08:00
Scott Shawcroft b4d3699047 Introduce reset mechanics to microcontroller.
This allows one to configure how a subsequent reset will behave and
also trigger a reset.

Fixes #350 and fixes #173

Dan Halbert e0ddd528c8 Add Processor to microcontroller documentation TOC (#237) 2017-09-06 17:50:00 -04:00
Dan Halbert fdb97eda09 Add microcontroller.cpu.temperature, for use as a simple sensor on minimal boards. (#211)
* Add microcontroller.cpu, the sole instance of microcontroller.Processor.
microcontroller.cpu.frequency is the clock frequency, in Hz.
microcontroller.cpu.temperature is the reading from the internal temperature sensor, in Celsius. None if not available.

* Squeeze firmware size by using -finline-limit. Otherwise non-Express builds were slightly too big.

* Update submodules.

* Fix documentation glitches

Dan Halbert ef61b5ecb5 Initial merge of micropython v1.9.2 into circuitpython 2.0.0 (in development) master.
cpx build compiles and loads and works in repl; test suite not run yet
esp8266 not tested yet

Scott Shawcroft 266be30777 atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. (#203)
* atmel-samd: Introduce a nvm module for non-volatile byte-level memory access.

This allows for persisting small configuration values even when the file system
is read-only from CircuitPython.

Fixes #160

* Review feedback:
* Add tests.
* Fix non-zero index.
* Fix len()

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 0ae344841f atmel-samd & esp8266: Make sure pins are not already in use.
This prevents corrupting previous functional objects by stealing their pins
out from under them. It prevents this by ensuring that pins are in default
state before claiming them. It also verifies pins are released correctly and
reset on soft reset.

Fixes #4, instantiating a second class will fail.
Fixes #29, pins are now reset too.

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 4933fa1c27 shared-bindings: Ensure pin objects are actually pins.
Fixes #12
2016-11-29 15:50:01 -08:00
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.
