audio_requirements.hpp File Reference

Audio driver requirements validator. More...

Detailed Description

Audio driver requirements validator.

Validates that audio drivers provide required functionality using the method detection system. This is the core audio contract enforcement for Sound Byte Libs drivers.

Audio Driver Contract

Every Sound Byte Libs audio driver MUST implement these methods:

• init() - Initialize with default settings
• init(const AudioConfig&) - Initialize with custom settings
• set_callback(AudioCallback) - Register processing callback
• start() - Begin audio streaming
• stop() - Stop audio streaming

Validation Usage

Add validation at the bottom of driver sai.hpp (or i2s.hpp, etc.):

#include <sbl/hw/validation/audio_requirements.hpp>
static_assert(sbl::validation::audio_driver_valid<sbl::driver::Sai>,
              "SAI driver missing required audio methods");
