Twi represents a struct containing registers for TWI.

Function Definition

pub fn write_sda()

Sets DDRC to write direction.

pub fn read_sda()

Sets DDRC to write direction.

Trait implementation

Impl new for Twi

pub fn new() -> &'static mut Self

Returns pointer to TWBR.

Impl wait_to_complete for Twi

pub fn wait_to_complete(&mut self, operation: u8) -> bool

Waits for the process to be complete.

Returns if process was successful.

Impl init for Twi

pub fn init(&mut self)

Initiates the Twi bus.

Impl start for Twi

pub fn start(&mut self) -> bool

Sends a start signal.

Impl rep_start for Twi

pub fn rep_start(&mut self) -> bool

Sends a Repeat Start Signal

Impl stop for Twi`

pub fn stop(&mut self)

Stops the Twi bus.

Impl set_address for Twi

pub fn set_address(&mut self, addr: u8) -> bool

Sets address of Slave.

Returns true if process is successful

Impl address_read for Twi

pub fn address_read(&mut self, address: u8) -> bool

Checks if slave is acknowledged.

Returns true if process is successful

Impl write for Twi

pub fn write(&mut self, data: u8) -> bool

Writes one byte of data to the Slave. Need to set address first.

Returns true if process is successful

Impl write_burstfor Twi

pub fn write_burst(&mut self, data: &FixedSliceVec<u8>) -> usize

Writes consecutive bytes of data to the Slave. Need to set address first.

Returns number of bytes written

Impl write_to_slave for Twi

pub fn write_to_slave(&mut self, address: u8, data: &FixedSliceVec<u8>) -> bool

Writes consecutive Data bytes to slave.

Returns true if process is completed and aborts if any of the steps.

Impl start for Twi

pub fn read_from_slave(

&mut self,

address: u8,

length: usize,

data: &mut FixedSliceVec<u8>,

) -> bool

Reads consecutive Data bytes from slave.

Returns true if process is completed and aborts if any of the steps.
