Dependencies

This crate, when used to build a final binarry assumes that certain linker symbols does exist and are defined. These are usually provided when using the ruspiro-boot crate which comes with a linker script providing all the necessary linker symbols and entrypoints calling into this crate once it is used.

Usage

To use the crate just add the following dependency to your Cargo.toml file:

[dependencies]
ruspiro-interrupt = "0.2.0"

Once done the access to the features/attribute of the interrupt crate is available in your rust files like so:

use ruspiro-interrupt::*;

#[IrqHandler(<irq-type-name>)]
unsafe fn my_handler() {

}

In rare cases the interrupt line is shared for different sources, in this case the attribute need to specify the source:

#[IrqHandler(<irq-type-name>, <source>)]
unsafe fn my_handler_for_source() {

}
