Struct AudioInterface

pub struct AudioInterface { /* private fields */ }

A wrapper around a mutable reference to the Audio Interface’s memory mapped registers.

See AudioInterface::new() for usage details.

Implementations

impl AudioInterface

pub unsafe fn new() -> Self

Creates a new wrapped mutable reference to the Audio Interface’s memory mapped registers, starting at 0xA4500000.

Developers are recommended to use Hardware::take() instead. But for unrestricted, unsafe, access, this struct provides a method-based version to the static functions available at the module level.

Safety

This provides unrestricted access to memory mapped registers. Data races could occur if writing to a register in both regular code and inside interrupt handlers.

This is especially problematic if performing a read-modify-write operation; an interrupt could trigger between reading a register, and writing a modified value back to the same register. Thus anything written to that register inside the interrupt, would only apply for a short moment before being overwritten.

Trait Implementations

impl Deref for AudioInterface

type Target = RegisterBlock

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for AudioInterface

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
