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 6839fff313 Move to ASF4 and introduce SAMD51 support. (#258)
* atmel-samd: Remove ASF3. This will break builds.

* atmel-samd: Add ASF4 for the SAMD21 and SAMD51.

* Introduce the supervisor concept to facilitate porting.

The supervisor is the code which runs individual MicroPython VMs. By
splitting it out we make it more consistent and easier to find.

This also adds very basic SAMD21 and SAMD51 support using the
supervisor. Only the REPL currently works.

This begins the work for #178.

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.

Dan Halbert 0d2c1bf2bb Fix problems that prevented use of internal frozen modules:
1. Allow -Wlto-type-mismatch to be just a warning when building with frozen modules.
2. Fix extern decls that triggered -Wnested-externs when building with frozen modules.
3. Pass the correct value of -mlongint-impl to $(MPY_TOOL). New file mpconfigport.mk to do this.

2017-06-28 16:18:13 -07:00
Scott Shawcroft a0058e6712 Introduce a random module that is a subset of CPython's random. It
also initializes in the same way where it takes from a true random
source when available through os.urandom(). After initializing, it
produces deterministic results until the seed is set.

This replaces urandom!

Fixes #139.

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

Scott Shawcroft 3e23464b1e atmel-samd: Add user initiated safe mode and rework board.c for
board specific functionality.

Fixes #155
2017-06-16 14:55:53 -07:00
Scott Shawcroft c7efd2cae9 shared-bindings: Move enum-like classes out of DigitalInOut into digitalio.
Also, rename Direction.IN to Direction.INPUT and Direction.OUT to Direction.OUTPUT.

This simplifies using them. Prior to the nativeio split this would have led to
clutter in the top-level namespace but having digitalio prevents this.

Fixes #152

Scott Shawcroft aaf01481aa Change the approach for input so that its not included in every single build. Put it next to readline instead. 2017-05-25 12:14:42 -07:00
Scott Shawcroft 32a4eb2c53 atmel-samd: Add input support. Fixes #143 2017-05-25 11:55:38 -07:00
Scott Shawcroft 3f5028c666 atmel-samd: Support wav file playback. Tested up to 16bit 22.1khz. Must be mono file!
SD card support may work but likely needs buffer tuning. Its untested.

Fixes #105
2017-05-15 19:52:38 -07:00
Scott Shawcroft 974847ac8d atmel-samd: Add a safe mode which detects hard faults and reboots without running user code again. 2017-05-15 15:29:04 -07:00
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 7672bf7736 atmel-samd: Rename auto-reset to auto-reload to reduce confusion with physical reset buttons. 2017-05-12 16:45:38 -07:00
Scott Shawcroft e1a6f6d584 atmel-samd: Rework SPI flash defines for clarity.

Scott Shawcroft 58b9789d0c atmel-samd: Introduce audio sample playback via audioio.AudioOut. 2017-05-01 13:10:03 -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 8d0d5defc7 atmel-samd: Use LTO for all builds to get 5000 bytes back on express boards. 2017-04-18 09:44:04 -07:00
Scott Shawcroft 67ec52d7a9 atmel-samd: Swap out pulseio for touchio based on FreeTouch. 2017-04-18 09:44:04 -07:00
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.
2017-04-10 13:32:19 -07:00
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.
2017-03-25 12:04:49 +00:00
Scott Shawcroft 7cb54864aa Add PulseIn support which can be used to measure a series of pulse widths.

Scott Shawcroft 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.

Scott Shawcroft cea5503ca0 Fixup warnings from merge about undefined macro values, switch to
VM keyboard exception and switch to FATFS reader.
2017-01-12 12:46:18 -08:00
