• Basic: clock init, delay, interrupt, etc.

• Dedicated runtime: interrupt table, hardware stack push, highcode support, critical section implementation

• embassy support

  • time driver with SysTick, defaults to 32KHz tick
  • about 7k flash rom overhead

• GPIO, with async support

Refer Cargo.toml and examples directory.
