v0.2.0 - Ecosystem Expansion

Multi-vendor BSP generation

  • 5 vendors with full YAML→IR→render pipelines: Espressif (9 chips,
    14 boards), Nordic nRF (nRF52840 + DK), NXP i.MX RT (MIMXRT1062 + EVKB),
    RP2040 (Pico), Renesas RA (R7FA6M5BH + EK-RA6M5).
  • Each vendor has a distinct pin routing model captured in vendor-specific IR
    types: ESP IO MUX + GPIO matrix, Nordic PSEL, NXP IOMUX ALT + daisy chain,
    RP FUNCSEL + RESETS, Renesas PFS PSEL + MSTP.
  • 6 MiniJinja templates per vendor generating real PAC register writes.
    rlvgl-creator bsp from-yaml --vendor CLI dispatch for all 5 vendors.
    bsp list-chips --vendor and bsp list-boards --vendor commands.
  • All 9 chipdb crates overhauled from legacy binary-blob stubs to YAML
    auto-discovery with chip_yaml() / board_yaml() / chip_names() /
    board_names() APIs.

UEFI backend

  • rlvgl-platform gains a uefi feature with GOP framebuffer display,
    SimpleTextInput keyboard polling (with synthesized KeyUp events), and Serial
    I/O playit transport for test automation over QEMU virtio-serial.
  • rlvgl-example-uefi-disco runs the disco-demo controller as a UEFI boot
    application.

Test automation (rlvgl-playit)

  • Serial test driver with touch injection, pointer/key events, multi-touch
    frames, widget queries, framebuffer pixel dumps, and event recording.
  • Node.js test harness for end-to-end simulator automation.
  • UEFI serial transport for pre-OS test driving.

STM32H747I-DISCO platform

  • DMA2D hardware acceleration with ISR-driven completion.
  • WM8994 audio codec over I2C4 + SAI1 I2S TX + SAI4 PDM microphone.
  • SDMMC block device with FATFS adapter for SD card assets.
  • QSPI flash support.
  • Star crawl motion system (mirrored starfield + FIR text overlay).
  • CPU stats via DWT/D3 SRAM telemetry.

FreeRTOS platform (new)

  • Preemptive task model: present (P3), render (P1), touch (P2), playit (P2).
    Interrupt-driven I2C4 touch via ISR state machine + FreeRTOS semaphore.
  • TIM7 one-pulse ERIF-phase-locked present with configurable holdoff.
  • Single-buffer FRONT rendering (32 ms holdoff, ~18 Hz, flicker-free).
  • Joystick (PK2-PK6) and button (PC13) input with keyboard navigation.
  • Star crawl integration with jumbo/CFBAR model + touch-to-dismiss.
  • DiscoCommand drain: star crawl, storage refresh, backlight, effects.
  • SVCall/PendSV naked trampolines via ffi_shims.c for FreeRTOS exception routing.
  • SysTick pre-scheduler gate to prevent xPortSysTickHandler on uninitialized data.
  • FT5336 CTRL=0x00 keep-active init; G_MODE left at default (0x00 kills touch).
  • make build-disco-freertos / make flash-disco-freertos build targets.

##Zephyr platform (existing, documented)

  • C+Rust hybrid: 440-line C shell (main.c) + 1,300-line Rust entry (zephyr_entry.rs).
  • Video mode (Zephyr DSI driver, landscape, DMA2D deadlocks) and adapted command
    mode (Rust raw DSI init, portrait, DMA2D works).
  • SYS_INIT PG3 early reset hook for FT5336 under adapted command mode.
  • INPUT_MODE_SYNCHRONOUS for dropped-event-free touch/joystick input.
    C1_LPENR CSleep fix for dual-core H747 display peripheral clock gating.
  • Star crawl pipeline functional under adapted command mode.

Platform guides (new)

  • Volume IV: FreeRTOS Platform Guide (7 chapters) — scaffolding, present task,
    touch ISR, render task, input dispatch, star crawl, flicker/rendering strategy.
  • Volume V: Zephyr Platform Guide (7 chapters) — build/link, C shell/FFI,
    display modes, touch/input, render loop, DMA2D, adapted command mode deep dive.

Rendering and UI

  • Anti-aliased rounded corners in core draw.
  • Compositor save-under and dirty-region restoration.
  • Focus highlights and keyboard navigation.
  • ColorFormat profile on Screen/DisplayDriver.
  • Motion primitives: Direction, MotionRate, JumboBuffer, BackgroundPattern,
  • Crawl trait, TextCrawl engine, CrawlWindow composable widget.

Infrastructure

  • All 31 workspace crates at version 0.2.0.
  • Publish script with 25-crate dependency-ordered publish and crates.io
    index-wait between dependents.
  • Pre-publish validation: 7 phases (fmt, clippy, tests, playit, creator,
    embedded build, docs).
