Required Associated Types

type Error

Required Methods

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

Read the value of a register

fn read_many<'b>( &mut self, reg: Register, buf: &'b mut [u8] ) -> Result<&'b [u8], Self::Error>

Read the value of a register larger than a single byte (the FIFO)

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

Write the value of a register

fn write_many(&mut self, reg: Register, bytes: &[u8]) -> Result<(), Self::Error>

Write values to a register larger than a single byte (the FIFO)

Provided Methods

fn rmw<F>(&mut self, reg: Register, f: F) -> Result<(), Self::Error>

where F: FnOnce(u8) -> u8,

Execute a read-modify-write operation
