# Deep Sleep — RTC Alarm Wakeup

Wake Inkplate 6 from deep sleep using a PCF85063A RTC alarm.

## Overview

Sets an alarm on the on-board PCF85063A RTC and uses it to wake Inkplate 6 from deep sleep at a precise time. On each wakeup, the current RTC time is read and displayed, then a new alarm is set before returning to deep sleep.

## Hardware Required

- Soldered Inkplate 6
- USB cable

## Setup

Run `idf.py menuconfig` and navigate to:
**Inkplate Boards → Inkplate6**

## Build and Flash

```
idf.py build
idf.py -p PORT flash monitor
```

## Expected Output

Current time displayed on screen after each RTC alarm wakeup. Board returns to deep sleep until the next alarm fires.

## Notes

- The PCF85063A RTC continues to run during deep sleep.
- RTC time must be set before the alarm will fire correctly.
