Module stm32_hal2::prelude

In the prelude, we export helper macros.

Macros

access_global

Syntax helper for getting global variables of the form Mutex<RefCell<Option>>> from an interrupt-free context - eg in interrupt handlers.

make_globals

Syntax helper for setting global variables of the form Mutex<RefCell<Option>>>. eg in interrupt handlers. Ideal for non-copy-type variables that can’t be initialized immediatiately.

make_simple_globals

Syntax helper for setting global variables of the form Mutex<Cell<>>>. eg in interrupt handlers. Ideal for copy-type variables.
