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: 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.

example: add MIDI 2.0 Host example with display (midi2_host)

2026-05-12T14:07:44Z

Add Host example that receives UMP from a MIDI 2.0 Device via PIO-USB and displays received messages on a SSD1306 OLED (I2C, 128x64). Features: - Boot checklist on display (PWR, TinyUSB, USB bus, Device, Descriptor, Alt Setting UMP, Mount, Receiving) - Decode and display all MIDI 2.0 Channel Voice messages - PIO-USB Host on rhport 1 (GP12/GP13 for Waveshare RP2350-USB-A) - SSD1306 display via I2C0 (GP4=SDA, GP5=SCL) Also add board definition for Waveshare RP2350-USB-A. Tested: Waveshare RP2350-USB-A (Host) receiving UMP from Raspberry Pi Pico (Device) via USB cable, notes displayed on SSD1306 OLED
