Power Management Example — C++

Source: apps/cpp/example_pm/src/app.cpp | WASM Demo{:target="_blank"}

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 C++20 RAII wrappers. Objects are declared at file scope — constructors handle initialization, destructors handle cleanup. Templates provide compile-time type safety.
