b1925b1bd8 atmel-samd: Fixup autoreset after switching boot to running once. 2017-05-15 20:21:26 -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

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.

e0f931afd3 atmel-samd: Fix pin reset to ensure USB and SWD are not reset. 2017-05-12 16:09:13 -07:00

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

7ea76e0889 atmel-samd: Pin reset improvements. 
* Reset SWD lines to SWD rather than GPIO. This makes OpenOCD happier.
* Default speaker enable lines to False for CircuitPlayground to prevent
  the speaker from buzzing when no sound is playing. Fixes #126

Rename LEFT_BUTTON -> BUTTON_A, RIGHT_BUTTON -> BUTTON_B. 2017-05-11 14:48:17 +01:00

c6d539ace3 atmel-samd: Fix sporadic "syntax errors" 
The GC was deleting memory that was in use because its scan of the
stack missed the very top. Switching to _estack fixes this by relying
on the location from the linker.

Fixes #124

5ad426124b atmel-samd: Move heap objects into MICROPY_PORT_ROOT_POINTERS so they don't get garbage collected while we are using them. 2017-05-04 11:57:51 -07:00
Scott Shawcroft
6512ccf32e atmel-samd: Use DMA for user SPI. 
Also replace use of PINMUX_DEFAULT with PINMUX_UNUSED to prevent any
accidental pin changes. This caused user SPI to break internal SPI
flash on the Feather M0 Express.

Fixes #100

24a5752f94 atmel-samd: Use DMA for SPI flash block transfers.

a9d25bfae4 atmel-samd: Update CircuitPlayground Express pins for Rev G. 2017-04-20 11:25:57 -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.

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.

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.

be1ed7aae4 Change to official Feather M0 Express branding. 2017-03-27 19:45:44 +01:00

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.

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.
