Summary

Major refactoring to upgrade embassy ecosystem dependencies and add several new peripheral drivers.

Changes

Dependency Upgrades

  • Upgrade embassy-* crates to latest versions (0.5.x/0.7.x/0.9.x)
  • Upgrade hpm-metapac to latest snapshot
  • Upgrade hpm-riscv-rt to 0.3.0 (fully compatible to new riscv/riscv-rt)
  • Upgrade defmt to 1.0.1
  • Upgrade riscv/riscv-rt to 0.15.0

New Features

  • PWM: Add SimplePwm driver with type-safe channel enable methods
  • Timer (GPTMR): Add comprehensive timer driver with delay, compare, and capture modes
  • Embassy Time Driver: Add alternative time driver using GPTMR (feature: time-driver-gptmr0/1)
  • EWDG: Add watchdog driver for HPM5300/HPM6200/HPM6300/HPM6800/HPM6E00 series
  • UART: Add buffered and ring-buffered UART drivers with DMA support
  • USB: Refactor and add remote wakeup, force full-speed mode, and VBUS detection support

Refactoring

  • Refactor USB driver state management to avoid static mut
  • Rewrite MCHTMR-based embassy time driver
  • Improve DMA ringbuffer implementation

Fixes

  • Fix all examples to work with new APIs
  • Rust 2024 edition compatibility (#[unsafe(link_section)], static_mut_refs)

Platforms Tested

  • HPM5300EVK
  • HPM6200EVK
  • HPM6750EVKMini
  • HPM6E00EVK

Breaking Changes

  • Peripheral names: WDG0 -> EWDG0, wdg -> ewdg
