Drivers

Hardware support, split by who owns the abstraction:

  • lhal/ — Longhorn HAL: our platform-independent peripheral interfaces. Application code depends on this and nothing else, so it builds for both the MCU and the host (tests, sims).
  • stm32/ — vendor code: ST's HAL, CMSIS, and FreeRTOS, packaged from pinned upstream commits, one subpackage per STM32 family.
