Matthias Blankertz	931571bd0a	audiocore: Add async support ... Rename the exising audiocore C module to _audiocore and create a new Micropython wrapper module audiocore. This makes it easier to implement async methods. Add interrupt support to _audiocore that notifies core0 whenever data has been consumed from the MP3 bitstream buffer. Use this interrupt and an asyncio.ThreadSafeFlag to implement audiocore.async_put which will play back the provided buffer, allowing other async tasks to run while waiting for space in the bitstream buffer.	2025-03-22 10:53:27 +01:00
