The BOX-3 touch gamebook had several blocking bugs that made the
voiced+foley story packs unusable. This fixes them end to end.
- Stack overflow on story start: gb_play_task kept a 2 KB buffer on
its 4 KB stack and rebooted the board. Buffers are now static (the
task is a singleton) and the stack is 6 KB.
- No sound at all: the ES8311 codec was never initialised — main.c
wrote raw I2S to a muted DAC. Output (and the mic) now go through
the BSP esp_codec_dev (bsp_audio_codec_speaker/microphone_init,
esp_codec_dev_write/read). The power amplifier (GPIO46) is also
forced on and volume set to 100, as the es8311 pa_pin handling did
not drive it in practice.
- First passage silent: gb_play re-mounted the SD that the gamebook
had already mounted; the failed second bsp_sdcard_mount tore down
the VFS so the first fopen failed. Now we open the file first and
only mount if that fails. A short silence lead-in also primes the
codec/PA ramp.
- No accents: the gamebook used ASCII-only lv_font_montserrat_14/24.
Added custom Montserrat fonts (font_fr_14/24, Latin-1 + œŒŸ « » ’ …,
uncompressed so they render without LV_USE_FONT_COMPRESSED).
- Mic/voice streaming gated behind CONFIG_BOX3_VOICE_STREAMING
(default off): as a gamebook the BOX-3 needs no mic, and the
constant codec reads + bridge reconnects interfered with playback
and flooded the log.
plip_virtual + cmd_exec handle types switched from i2s_chan_handle_t
to esp_codec_dev_handle_t accordingly.
