embedded-hal-bus

Bus/Device connection mechanisms for [embedded-hal], a Hardware Abstraction Layer (HAL) for embedded systems.

It is possible to connect several peripherals to a bus like SPI or I2C. To support this, embedded-hal provides the SpiBus and SpiDevice traits in the case of SPI, for example.

embedded-hal trait implementations for microcontrollers should implement the ...Bus traits. However, device drivers should use the ...Device traits, not the ...Bus traits if at all possible in order to allow for sharing of the bus they are connected to.

This crate provides mechanisms to connect a ...Bus and a ...Device.

For further details on these traits, please consult the embedded-hal documentation.

This project is developed and maintained by the HAL team.
