Module rp6::avr::interrupt

Routines for managing interrupts. Based on:

• https://github.com/avr-rust/ruduino/blob/master/src/interrupt.rs
• https://docs.rs/bare-metal/0.2.5/src/bare_metal/lib.rs.html

Modules

mutex

Module to allow safe access of shared data structures within a CriticalSection.

Structs

CriticalSection

Helper struct that automatically restores interrupts on drop. The wrapped PhantomData creates a private field to ensure that this struct cannot be initialized from outside of this module without using its unsafe initializer function new. The recommended use to enter a CriticalSection is to pass a closure to without_interrupts.

Statics

CRITICAL_SECTION_COUNTER 🔒

Atomic counter of critical sections to avoid problems when without_interrupts is used in nested function calls.

Functions

without_interrupts

Executes a closure, disabling interrupts until its completion. Introduces a CriticalSection that allows to access shared data structures via the guards provided in the mutex module.
