COMPILER_WORD_ALIGNED as done in #118 for mouse. Added COMPILER_WORD_ALIGNED
to other UDC_DESC_STORAGE declarations that might have the same issue in
the future.
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
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.
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.
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
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.
* 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
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
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
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.
* 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.
