An MPU communication device abstraction

This allows us to generalize the device over either an I2C or SPI peripheral

Associated Types

type Error

The type of error for all results

Required methods

fn read_many<N: ArrayLength<u8>>(
    &mut self,
    reg: Register
) -> Result<GenericArray<u8, N>, Self::Error>

Read many values from register

fn write(&mut self, reg: Register, val: u8) -> Result<(), Self::Error>

Write the provided value to register

Provided methods

fn read(&mut self, reg: Register) -> Result<u8, Self::Error>

Read a single value from the register

fn modify<F>(&mut self, reg: Register, f: F) -> Result<(), Self::Error> where
    F: FnOnce(u8) -> u8, 

Modify the value in the register using the provided closure. The closure accepts the current value of the register, permitting conditional checks before modification.
