Power Management Example — C

Source: apps/c/example_pm/src/app.c | WASM Demo

Demonstrates the PM state machine with automatic idle transitions, peripheral power domain reference counting, wake source registration (GPIO button + UART), custom battery-aware power policy, transition notifications, and runtime power statistics.

Language-specific patterns

This example uses the heap-mode C API with _create() / _destroy() calls. For zero-heap builds, switch to _init() / _deinit() with caller-supplied storage or use OVE_*_DEFINE_STATIC() at file scope (the latter also works in heap mode).

See the overview for architecture details and the full API list.
