Add subclass support to displayio.

Also, swap make_news to accept a kwarg map and refine param checking. Fixes #1237

Compress all translated strings with Huffman coding.

2018-08-17T00:40:57+00:00

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.

Support internationalisation.

Make resume idempotent (allowing you to call it twice without complaining.)

Tweak exception message.

Add pause/resume control to AudioOut and I2SOut

Fixes #808

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.

Add audio output support!

2018-04-12T23:35:13+00:00

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
