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	2018-04-12 16:35:13 -07:00

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

Add Feather M4 Express support.

* Also fixed detection of SPI flash chip to correct look in the 2+
spots.
* Added support for using QSPI in dual read mode.
