Scott Shawcroft 51cd4da76e atmel-samd: Add mass storage support.
Fixes #260

Scott Shawcroft 80654779e1 atmel-samd: Add support for internal filesystems. (#311)
* atmel-samd: Add support for internal filesystems.

This allows us to re-enable `os`. `random` is also enabled because
it solely depends on `os`.

Fixes #266. Its also a pre-requisite for #260.

* atmel-samd: Update SAMD51 linker script comments and MICROPY_MAX_STACK_USAGE enabling.

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()

Fixes for stmhal USB mass storage, lwIP bindings and VFS regressions

This release provides an important fix for the USB mass storage device in
the stmhal port by implementing the SCSI SYNCHRONIZE_CACHE command, which
is now require by some Operating Systems.  There are also fixes for the
lwIP bindings to improve non-blocking sockets and error codes.  The VFS has
some regressions fixed including the ability to statvfs the root.

All changes are listed below.

py core:
- modbuiltins: add core-provided version of input() function
- objstr: catch case of negative "maxsplit" arg to str.rsplit()
- persistentcode: allow to compile with complex numbers disabled
- objstr: allow to compile with obj-repr D, and unicode disabled
- modsys: allow to compile with obj-repr D and PY_ATTRTUPLE disabled
- provide mp_decode_uint_skip() to help reduce stack usage
- makeqstrdefs.py: make script run correctly with Python 2.6
- objstringio: if created from immutable object, follow copy on write policy

extmod:
- modlwip: connect: for non-blocking mode, return EINPROGRESS
- modlwip: fix error codes for duplicate calls to connect()
- modlwip: accept: fix error code for non-blocking mode
- vfs: allow to statvfs the root directory
- vfs: allow "buffering" and "encoding" args to VFS's open()
- modframebuf: fix signed/unsigned comparison pendantic warning

lib:
- libm: use isfinite instead of finitef, for C99 compatibility
- utils/interrupt_char: remove support for KBD_EXCEPTION disabled

tests:
- basics/string_rsplit: add tests for negative "maxsplit" argument
- float: convert "sys.exit()" to "raise SystemExit"

zephyr port:
- modusocket: getaddrinfo: Fix mp_obj_len() usage

- machine_pin: use native Zephyr types for Zephyr API calls

docs:
- machine.Pin: remove out_value() method
- machine.Pin: add on() and off() methods
- esp8266: consistently replace Pin.high/low methods with .on/off
- esp8266/quickref: polish Pin.on()/off() examples

- uos: move cc3200 port legacy VFS mounting functions to its ref doc
- machine: sort machine classes in logical order, not alphabetically
- network: first step to describe standard network class interface

examples:
- embedding: use core-provided KeyboardInterrupt object

Scott Shawcroft 790c38e18c atmel-samd: Rework boot, main and REPL order.
Boot will only run once now before USB is started. Its output goes to
boot_out.txt. After main and REPL will run with VM and hardware resets
between each.

Scott Shawcroft e1a6f6d584 atmel-samd: Rework SPI flash defines for clarity.
Also add sector protection support for the SAMD Xplained board.

Scott Shawcroft 24a5752f94 atmel-samd: Use DMA for SPI flash block transfers.
Fixes #99

Scott Shawcroft 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.

Scott Shawcroft b6f1eebab3 atmel-samd: Add APA102 support and flash more advanced status.
The new sequence is as follows:
* Solid blue during the boot/settings script.
* Solid green during the main/code script.
* After main while waiting to enter repl or reset:
  * Fading green once main is done successfully.
  * On error produce a series of flashes:
    * Long flash color of script.
    * Long flash color of error:
      * Green = IndentationError
      * Cyan = SyntaxError
      * White = NameError
      * Orange = OSError
      * Yellow = Other error
    * Line number of the exception by digit. Number of flashes represents value.
      * Thousands = White
      * Hundreds = Blue
      * Tens = Yellow
      * Ones = Cyan
    * Off for a period and then repeats.

At any point a write to the flash storage will flicker red.

Fixes #63

Scott Shawcroft 2d9a0c76c5 atmel-samd: Switch to MICROPY_PORT_ROOT_POINTERS for the flash cache. 2016-11-29 14:29:33 -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.

Scott Shawcroft 5b3a143ffe atmel-samd: Rework tick timer to use TC5 and support neopixel status LED.
The tick timer needed to be reworked because the ASF delay functions also
use the SysTick timer. Now, it uses TC5 and calls out to the autoreset
logic every tick. Fixes #43.

Added neopixel status colors and corrected the latch time from ms to us.
Fixes #42.

Scott Shawcroft d189a3f3cf atmel-samd: Support auto-reset based on USB write activity.
It will soft-reboot micropython after a burst of writes to the
file system. This means that after you save files on your computer
they will be automatically rerun.

This can be disabled in the build by unsetting AUTORESET_TIMER in
mpconfigboard.h.

Using the REPL will also prevent the soft resets until you reset
with CTRL-D manually.

Scott Shawcroft d05299f57a atmel-samd: Add D13 led as mass storage write indicator. 2016-10-25 15:06:05 -07:00
Scott Shawcroft 9eb86e8015 Add support for USB writeable, MicroPython read-only volumes.
This prevents file system corruption due to two systems mutating
it at once.

Scott Shawcroft 306c921ed1 atmel-samd: Rework mass storage interaction with underlying block
storage to use micropython's VFS interface.

This makes mass storage work with any VFS implementation rather
than a single one.
