2019-11-25shared-bindings: I2SOut: Ensure object is deinitialisedJeff Epler
(or deinitialized, for those of us on this side of the pond) Otherwise, a sequence like ``` audio = audiobusio.I2SOut(bit_clock=board.D6, word_select=board.D9, data=board.D10) sine_wave_sample = audiocore.RawSample(sine_wave) audio.play(sine_wave_sample, loop=True) del audio ``` could free the memory associated with audio without stopping the related background task. Later, when fresh objects are allocated within a now-freed memory region, they can get overwritten in the background task, leading to a hard crash. This presumably can affect multiple I2S implementations, but it was reported against the nRF one.

2019-01-14Add subclass support to displayio.Scott Shawcroft
Also, swap make_news to accept a kwarg map and refine param checking. Fixes #1237
2018-08-16Compress all translated strings with Huffman coding.Scott Shawcroft
This saves code space in builds which use link-time optimization. The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531.

2018-05-01Re-enable PDMIn without ASF and using the helpers added withScott Shawcroft
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.
2018-04-12Add audio output support!Scott Shawcroft
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

2017-12-13Fix PDMIn MEMS microphone support (#479)Dan Halbert
Changes: * New faster filter loop, by @ladyada. New filter coefficients as well. * Turn on microphone clock when PDMIn object is created, and run it all the time, so the user code doesn't have to wait for microphone startup, which can be 10ms or even 100ms. * Wait for microphone startup when PDMIn is first created, based on new optional parameter microphone_startup in seconds (takes a float). * record() returns number of samples actually recorded, so you can see if it's not keeping up. * Fix buffer overflow errors when buffer size was not a multiple of 16 or something like that. * Tweak a few peripheral settings. * Minimum sampling frequency is now 16kHZ or so, because 8kHz runs microphone at only 0.5MHz, which is too slow for many mics. Note: I tried 128x oversampling instead of 64x, but the code cannot keep up at 24kHz or above sampling. 128x would reduce the high-frequency noise by 6db.
