docs: add build-doc tooling and a README for every example

2026-06-29T03:16:25Z

Documentation tooling: - Add the `build-doc` skill and `tools/build_doc.py` wrapper for local Sphinx builds (clean / -W / open). - Enable Markdown (MyST) in conf.py and auto-collect examples/{device,host,dual}/*/README.md into a 3-level Examples nav (Examples > Device/Host/Dual > example), noting each page's source location and normalizing headings to a single H1. - Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md Documentation section at the skill. Example docs: - Add a README.md for every device/host/dual example: what it does, USB interface table, notable tusb_config.h settings, generic CMake + Make build steps, and how to try it. - Fold each *_freertos variant into its base README, noting the FreeRTOS source path and any RTOS-specific behavior. Generated docs/examples/ output is git-ignored. Builds clean with `sphinx-build -W`. Co-Authored-By: Claude Opus 4.8 (1M context)

midi2_host: silence IAR Pe550 for midi2_idx

2026-05-29T17:46:16Z

The variable is set in mount/umount callbacks but not read elsewhere in the example (rx_cb already receives idx as a parameter). IAR treats Pe550 as an error under --warnings_are_errors. Tag it TU_ATTR_UNUSED so the example still shows the pattern of tracking the device index without erroring on unused-set. Co-Authored-By: Claude Opus 4.7

midi2_host: drop unreachable return 0 for IAR Pe111

2026-05-29T17:42:14Z

Same fix as midi2_device — IAR rejects the unreachable statement after the while(1) superloop. Let int main fall off the end. Co-Authored-By: Claude Opus 4.7

midi2: skip.txt comments

midi2: skip 3 more boards with same tcpp0203 BSP bug

2026-05-17T01:37:45Z

stm32h573i_dk, stm32n657nucleo and stm32n6570dk have the same pre-existing uninitialized io_ctx.GetTick in their board.h that we already skip on stm32h7s3nucleo. Trips with Make+LTO; CMake passes.

midi2: add sources to TINYUSB_SRC_C, skip family

2026-05-17T00:35:21Z

Make build was missing midi2_device.c/midi2_host.c from src/tinyusb.mk. Skip stm32h7s3nucleo board which exposes a pre-existing uninitialized warning in its board.h (board_init2) under Make+LTO.

midi2: fix CI matrix with only.txt and skip.txt

2026-05-16T23:39:20Z

Restrict midi2_host build to MCUs with USB host support (cloned from midi_rx) and skip SAMD11 from midi2_device (ROM overflow on link).

midi2: host example - simplify and rename to midi2_host

2026-05-16T16:00:30Z

Drop Feather-specific scaffolding (SSD1306 display, font, PIO-USB pin override) and rename the directory to midi2_host. The example is now a single main.c + tusb_config.h pair following the midi_rx pattern, with a printf-only UMP decoder for Channel Voice messages. Build-tested on adafruit_feather_rp2040_usb_host, daisyseed (stm32h7), mimxrt1010_evk, stm32f407disco, raspberry_pi_pico2, b_u585i_iot2a, portenta_c33, stm32h503nucleo, stlinkv3mini, feather_stm32f405.

refactor: replace midi2_host (Waveshare) with midi2_host_feather

2026-05-12T14:07:45Z

Remove the Waveshare RP2350-USB-A host example and board definition. The Feather RP2040 USB Host is the TinyUSB reference board for PIO-USB host and does not require the CFG_TUSB_DEBUG workaround needed by the Waveshare (R13 pull-up issue). One host example is sufficient for the PR. The Feather variant has an improved display with splash, spinner, and 6-line live view.
