Detailed Description

Audio driver interface - canonical types and convenience functions.

This header provides the portable audio API for Sound Byte Libs.

Audio Driver Contract

Drivers implement the following static interface:

static void init() - Configure with defaults static void init(const AudioConfig&) - Configure with custom settings static void set_callback(AudioCallback) - Register processing function static void start() - Begin streaming static void stop() - Stop streaming

Every block the driver clocks out advances SampleClock by its frame count (sample_clock.hpp), after the callback returns — the elapsed-samples source for control code.

Convenience Functions

sbl::audio::start<sbl::driver::Sai>(my_callback); sbl::audio::stop<sbl::driver::Sai>();

Usage in application: #include <sbl/hw/hal/audio/driver.hpp> #include <sbl/hw/driver/sai.hpp>

sbl::audio::start<sbl::driver::Sai>(audio_callback);
