embedded-hal

The embedded-hal crate provides a number of traits covering common microcontroller peripherals.

  • GPIO
  • ADC
  • I2C, SPI, UART, CAN
  • RNG
  • Timers
  • Watchdogs

Other crates then implement drivers in terms of these traits, e.g. an accelerometer driver might need an I2C or SPI bus implementation.

  • There are implementations for many microcontrollers, as well as other platforms such as Linux on Raspberry Pi.
  • There is work in progress on an async version of embedded-hal, but it isn't stable yet.
