2017-09-06Ctrl-C was causing a soft-reset in REPL.Dan Halbert
Also allow an immediate ctrl-c in `input()`.

quiet. Also update the examples. Fixes #226
2017-09-01Fix issue #207, esp8266 file operations problems (#222)Dan Halbert
The frozen module `_boot.py` was not being loaded on restart because `pyexec_frozen_module()` did not know about the new `.frozen` pseudo-directory. Updated lower-level routine to look in the right place. Also made ".frozen" and related values be `#define`s.
2017-09-01atmel-samd: Remember SPI baudrate.Scott Shawcroft
This prevents the SERCOM from blipping the data line on each transaction and therefore fixes #219.

visible on boot.
2017-08-31Add microcontroller.cpu.temperature, for use as a simple sensor on minimal ↵Dan Halbert
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.

Fixes #194
2017-08-11Turn on Rosie CI testing to test new builds on real hardware.Scott Shawcroft
This introduces a skip_if module that can be used by tests to determine when they should be skipped due to the environment. Some tests have been split in order to have finer grained skip control.

microphones.
2017-07-23Measure and report maximum stack usage. (#175)Dan Halbert
Add max stack usage tracking, visible via debug module ustack. Add separate cpp flag for enabling modules: MICROPY_DEBUG_MODULES
2017-07-16Fix problems that prevented use of internal frozen modules:Dan Halbert
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.
2017-07-13atmel-samd: Fix potential buffer overflow in UART.c by recalculatingScott Shawcroft
the buffer end rather than naively adding 1. It could have needed to wrap around. Thanks @dhalbert for spotting the bug. Fixes #132
2017-07-13atmel-samd: Update README and add pinout tables that map MCU namesScott Shawcroft
to names in the board module and explain pin capabilities. Fixes #149
2017-07-12atmel-samd: Reboot to bootloader when a 1200 baud serial connection isScott Shawcroft

writeable and prevent USB from editing it.
2017-06-28atmel-samd: Update sys.path with correct root path.Scott Shawcroft
2017-06-28atmel-samd: update boot output location for new mount point.Scott Shawcroft
2017-06-28Change vfs mount ordering such that the root is always last in theScott Shawcroft
linked list. Its also the only one statically allocated and made available over USB.
2017-06-28atmel-samd: Update sys.path to match that the internal/onboardScott Shawcroft
flash is now at / rather than /flash.
2017-06-27Introduce a random module that is a subset of CPython's random. ItScott Shawcroft
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.
2017-06-27Split uos module into os and storage.Scott Shawcroft
os is a subset of CPython's os. storage contains additional file system mounting functionality based on UNIX's mount management. Fixes #140

an issue at startup leading to safe mode and mass storage support not working.
2017-06-20Merge tag 'v1.9.1'2.0.0-alpha.0Scott Shawcroft
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.

2017-06-16atmel-samd: Introduce board reset mechanic used on CircuitPlayground1.0.0-rc.1Scott Shawcroft
Express to ensure the Neopixels are off after reloads.
2017-06-16atmel-samd: Add user initiated safe mode and rework board.c forScott Shawcroft
board specific functionality. Fixes #155
2017-06-16shared-bindings: Move enum-like classes out of DigitalInOut into digitalio.Scott Shawcroft
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
2017-06-12atmel-samd: Fix sharing TCCs by statically storing the current period.Scott Shawcroft
A previous fix improved the duty_cycle channel value computation by removing the reliance on the PER register which gave old values. It saved the period on the object but failed to set anything for reused timers. So, this breaks it out into a separate array that can be shared across all object regardless of whether it used a new or existing timer.
2017-06-12atmel-samd: Fix TCC1, its two channels and four wave outputs.Scott Shawcroft
Previously it was configured as four and four which configured the incorrect channels.
2017-06-09atmel-samd: Set up the tcc_instance when using an already active TCC.Scott Shawcroft
This fixes a hard lock that happens when using a second channel on an in use TCC. The lock occurred when setting the duty cycle on the channel because the hw address was not available to ASF. Thanks to @ladyada for finding the bug.
2017-06-09atmel-samd: Reset TCC channel in use array on reset.Scott Shawcroft
This fixes spurious "All timers in use" exceptions. Thanks to @ladyada for finding this issue.
