CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=encoding 2019-07-25T11:44:26+00:00 2019-07-25T11:44:26+00:00 Jeff Epler jepler@gmail.com 2019-07-25T01:57:32+00:00 urn:sha1:6b44e40ee8dba415213468afe14f7202b42ec429 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`. 2018-10-16T23:23:29+00:00 Scott Shawcroft scott@tannewt.org 2018-10-09T20:56:02+00:00 urn:sha1:c209165d4357708c5d9ed08f150206cad36e6281 This reduces the popping sound on initial playback of an audio sample. The M4 DAC has a pop on startup that cannot be prevented. It also does not allow readback so current values of the DAC are ignored.

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.
