Implementations

impl SioFifo

pub fn is_read_ready(&mut self) -> bool

Check if the inter-core FIFO has valid data for reading.

Returning true means there is valid data, false means it is empty and you must not read from it.

pub fn is_write_ready(&mut self) -> bool

Check if the inter-core FIFO is ready to receive data.

Returning true means there is room, false means it is full and you must not write to it.

pub fn status(&self) -> u32

Return the FIFO status, as an integer.

pub fn write(&mut self, value: u32)

Write to the inter-core FIFO.

You must ensure the FIFO has space by calling is_write_ready

pub fn read(&mut self) -> Option<u32>

Read from the inter-core FIFO.

Will return Some(data), or None if the FIFO is empty.

pub fn drain(&mut self)

Read from the FIFO until it is empty, throwing the contents away.

pub fn write_blocking(&mut self, value: u32)

Push to the FIFO, spinning if there’s no space.

pub fn read_blocking(&mut self) -> u32

Pop from the FIFO, spinning if there’s currently no data.
