Jeff Epler 6b44e40ee8 audiocore: Factor from audioio
When nrf pwm audio is introduced, it will be called `audiopwmio`.  To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.

INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.

Move pin struct to the peripherals library.
Its slimmed down by removing the qstr and bit packing TCC info.

The trinket m0 build actually grows by 20 bytes. The arduino zero
build shrinks by 188 bytes.

Scott Shawcroft a5e03b76a6 Split out the peripherals library in preparation of sharing with MakeCode. 2018-06-15 16:16:21 -07:00
Scott Shawcroft fd71e56891 atmel-samd: Re-org helper peripheral files into their own subdirectory.
Ideally in the future they won't depend on ASF4 or MicroPython.

Scott Shawcroft cfea51ec68 Re-enable PDMIn without ASF and using the helpers added with
I2SOut.

The API is almost the same except the frequency attribute has been
renamed to sample_rate so that its less likely to be confused with
frequencies within the audio itself.

Fixes #263.

Scott Shawcroft 28642ab10d Add audio output support!
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263
