Scott Shawcroft 97fcdfbd08 docs: Update design guide for new DigitalInOut API. 2017-06-19 09:06:46 -07:00
Scott Shawcroft a715bf6bac atmel-samd: Introduce board reset mechanic used on CircuitPlayground
Express to ensure the Neopixels are off after reloads.
2017-06-16 15:40:15 -07:00
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 58ab5844cb atmel-samd: Fix sharing TCCs by statically storing the current period.
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.

Scott Shawcroft c61e1b89aa atmel-samd: Fix TCC1, its two channels and four wave outputs.
Previously it was configured as four and four which configured
the incorrect channels.
2017-06-12 15:36:09 -07:00
Scott Shawcroft 736a63e85a atmel-samd: Set up the tcc_instance when using an already active TCC.
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.

Scott Shawcroft 3658c92270 atmel-samd: Reset TCC channel in use array on reset.
This fixes spurious "All timers in use" exceptions. Thanks to
@ladyada for finding this issue.

Scott Shawcroft 9434db07b2 atmel-samd: Handle TCC2 correctly. Unlike the other TCCs its 16bit
rather than 24bit. Setting the period for more than a 16bit number
caused the TCC to be in a weird state where resetting it would hard
crash.

Fixes #153

Scott Shawcroft 43881f933d py: Prevent mp_arg_check_num from being optimized away by the compiler.
Also, change the MICROPY_ERROR_REPORTING checks to macros to make it
clear the compiler can handle it immediately.

Fixes #154

Scott Shawcroft 3f5028c666 atmel-samd: Support wav file playback. Tested up to 16bit 22.1khz. Must be mono file!

between each.

Scott Shawcroft 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.

Scott Shawcroft 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.
