Matthias Blankertz	34f9a44cdb	schematic: Fix I2S_SD pullup ... Sparkfun I2S audio board already has MAX98357A SD pin pullup for mono mode, so external pullup is redundant and can actually cause issues. Remove it.	2025-07-22 22:07:44 +02:00

Matthias Blankertz	d02776eea8	Add basic application for playback based on NFC tags ... Copy and clean up test.py to main.py. Add app module (currently on app.py, maybe make it a directory later) for application classes. Implement app.TimerManager to allow scheduling of delayed events in the micropython async framework. Implement app.TagPlaybackManager which handles playing back MP3 files based on the NFC tag reader. Currently, simply plays all MP3 files in a folder, for which the folder name matches the tag id, in order. Resume, random and other features not yet supported.	2025-05-20 22:04:27 +02:00

Matthias Blankertz	7f8282315e	Restructure sources ... The python and C modules that are supposed to be built into the firmware image (i.e. those that are in manifest.py or in USER_C_MODULES) have been moved to the software/modules directory. The software/src directory should now only contain python scripts and other files that should be installed to the Picos flash filesystem. The idea is that these should be those scripts that implement the application behaviour, as these are the ones that a user who does not want to build the whole firmware themself wants to modify.	2025-04-01 22:05:30 +02:00

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
