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 |
