Macro to override a device specific interrupt handler
Syntax
ⓘThis example is not tested
interrupt!( // Name of the interrupt $Name:ident, // Path to the interrupt handler (a function) $handler:path, // Optional, state preserved across invocations of the handler state: $State:ty = $initial_state:expr, );
Where $Name
must match the name of one of the variants of the Interrupt
enum.
The handler must have signature fn()
is no state was associated to it;
otherwise its signature must be fn(&mut $State)
.
