Web2 days ago · alarm – Alarms and sleep. alarm. – Alarms and sleep. Provides alarms that trigger based on time intervals or on external events, such as pin changes. The program can simply wait for these alarms, or go to sleep and be awoken when they trigger. There are two supported levels of sleep: light sleep and deep sleep. WebAn immediate answer that comes to mind is external interrupts. Problem is, CircuitPython doesn't support them — they are an advanced feature, and since the callback code has its own limitations, they were skipped in the current implementation.
