SUKU I2S codec component with TEK1 integration#317
Draft
Conversation
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Integrate stb_hexwave (double precision) for band-limited waveform generation. Sound plays continuously while endless encoder button is held, with frequency sweeping from 220Hz to 4kHz. Changed I2S to 16-bit 2-slot TDM config for NS4168 amplifier. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Generate samples one at a time for smooth continuous frequency sweep. Keep I2S channel always enabled and write zeros when idle to avoid DC offset power draw on NS4168. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Add gaon/gaoff/gac Lua functions with macros in grid_protocol.h - Replace hardcoded sweep with configurable freq/volume/waveform state - Add grid_lua_api_codec component files and wire into grid_module.c - Move codec init/ownership to app_main, decoupled from tek1 driver Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- gaon/gaoff map directly to init/deinit, removing enable/disable layer - init guarded by tx_chan NULL check; deinit resets tx_chan to NULL - removed enabled flag and zero-fill ISR branch - volume range changed from 0-127 to 0.0-1.0 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
