Jeff Epler dddd25a776 Combine similar strings to reduce size of translations
This is a slight trade-off with code size, in places where a "_varg"
mp_raise variant is now used.  The net savings on trinket_m0 is
just 32 bytes.

It also means that the translation will include the original English
text, and cannot be translated.  These are usually names of Python
types such as int, set, or dict or special values such as "inf" or
"Nan".

Jeff Epler a580f0f1c4 _pew: move to common-hal
I noticed that this code was referring to samd-specific functionality,

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.

warriorofwire eb3d5fa453 ujson: do not eat trailing whitespace
Ujson should only worry about whitespace before JSON.  This becomes apparent when you are using MP stream protocol to read directly from input buffers.

When you attempt to read(1) on a UART (and possibly other protocols) you have to wait for either the byte or the timeout.

Fixes:
- Waiting for a timeout after you have completed reading a correct and complete JSON off the input.
- Raising an OSError after reading a correct and complete JSON off the input.
- Eating more data than semantically owned off the input buffer.
- Blocking to start parsing JSON until the entire JSON body has been loaded into a potentially large, contiguous Python object.

Code you would write before:
```
line = board_busio_uart_port.read_line()
json_dict = json.loads(line)
```
or reaching for fixed buffers and swapping them around in Python.

Code that did not work before that does now:
```
json_dict = json.load(board_busio_uart_port)
```

- This removes the need for intermediate copies of data when reading JSON from micropython stream protocol inputs.
- It also increases total application speed by parsing JSON concurrently with receiving on boards that read from UART via DMA.
- It simplifies code that users write while improving their apps.

Jeff Epler cb6193bbc7 samd: When possible, use one DMA channel for stereo AudioOut
.. the documentation doesn't make this clear, but in practice it works
to write both of the DATABUF registers at the same time.  This should
also reduce the amount of wear and tear DMA puts on the system, as the
number of transfers is cut in half.  (the number of bytes transferred
remains the same, though)

In principle, this could cover all stereo cases if audio_dma_convert_signed
also learned to 16-bit extend and swap values.  However, this is the
case that matters for stereo mp3 playback on PyGamer.

Testing performed: Listened to some tracks with good stereo separation.

Jeff Epler 1905d0746d samd: neopixel: Fix neopixels after #2297
This adapts the "inline assembler" code from the UF2 bootloader, which
in turn is said to be adapted from the arduino neopixel library.

This requires the cache remain ON when using M0, and be turned OFF on M4
(determined by trial and error)

Testing performed on a Metro M4:
 * measured timings using o'scope and found all values within
   datasheet tolerance.
 * Drove a string of 96 neopixels without visible glitches
 * on-board neopixel worked

Testing performed on a Circuit Playground Express (M0):
 * Color wheel code works on built-in neopixels
 * Color wheel code works on 96 neopixel strip

As a bonus, this may have freed up a bit of flash on M0 targets. (2988 ->
3068 bytes free on Trinket M0)

Jeff Epler 7f744a2369 Supervisor: move most of systick to the supervisor
This code is shared by most parts, except where not all the #ifdefs
inside the tick function were present in all ports.  This mostly would
have broken gamepad tick support on non-samd ports.

The "ms32" and "ms64" variants of the tick functions are introduced
because there is no 64-bit atomic read.  Disabling interrupts avoids
a low probability bug where milliseconds could be off by ~49.5 days
once every ~49.5 days (2^32 ms).

Avoiding disabling interrupts when only the low 32 bits are needed is a minor
optimization.

Testing performed: on metro m4 express, USB still works and
time.monotonic_ns() still counts up

Track unadjusted PWM duty cycle to avoid accumulating conversion errors
Fixes #2086

When the frequency of a `PWMOut` is change it re-sets the PWM's duty cycle as
well, since the registers have to be re-calculated based on the new frequency.
Unfortunately, `common_hal_pulseio_pwmout_get_duty_cycle`
will return a value very close to, but not exactly, the value passed to `common_hal_pulseio_pwmout_set_duty_cycle`. If the frequency is modified
without the calling code also re-setting the duty cycle then the duty cycle
will decay over time. This fixes that problem by tracking the unadjusted duty
cycle and re-setting the duty cycle to that value when the frequency is changed.

jepler 61698eb5d8 AnalogOut / AudioOut: Copy settings from Arduino
Make changes in asf4_conf even though I think in these cases the
"peripherals" submodule is running the show.

Arduino clocks the DAC at 12MHz but uses the CCTRL setting for
clocking < 1.2MHz (100kSPS).

A fresh clock (6) is allocated for the new 12MHz clock.  This matches
the Arduino value, though not the GCLK index.

Modify other settings to more closely resemble Arduino.

In AudioOut, actually clock the waveform data from the timer we set up
for this purpose.

This gives good waveforms when setting AnalogOut full-scale in a loop,
but the rise/fall of waveforms that come from AudioOut are still erratic.
Weirdly, if AudioOut limits its range even slightly (e.g., to 1000..64000)
then the erratic

Note that this will require https://github.com/adafruit/samd-peripherals/pull/26
to be accepted for the submodule update here to work.

jepler 30a9346373 samd: audio_dma: Track channel allocation
Previously, we depended on allocated channels to always be
"dma_channel_enabled".  However, (A) sometimes, many operations
would take place between find_free_audio_dma_channel and
audio_dma_enable_channel, and (B) some debugging I did led me to believe
that "dma_channel_enabled" would become false when the hardware ended
a scheduled DMA transaction, but while a CP object would still think it
owned the DMA channel.

((B) is not documented in the datasheet and I am not 100% convinced that
my debugging session was not simply missing where we were disabling the
channel, but in either case, it shows a need to directly track allocated
separately from enabled)

Therefore,
 * Add audio_dma_{allocate,free}_channel.
   * audio_dma_free_channel implies audio_dma_disable_channel
   * track via a new array audio_dma_allocated[]
 * clear all allocated flags on soft-reboot
 * Convert find_free_audio_dma_channel to audio_dma_allocate_channel
   * use audio_dma_allocated[] instead of dma_channel_enabled() to check
     availability
 * remove find_free_audio_dma_channel
 * For each one, find a matching audio_dma_disable_channel to convert
   to audio_dma_free_channel
