Overview

The LilyGoBattery module is responsible for monitoring and managing the battery voltage and percentage for a LilyGo device. It provides telemetry data, processes commands, and manages sleep cycles to optimize power usage.

Features

• Reads battery voltage using an ADC pin.
• Calculates battery percentage based on voltage readings.
• Logs battery voltage and percentage periodically.
• Implements a light sleep mechanism to conserve power.
• Automatically reboots the device after 100 hours of uptime.

UI Hardware / Pinout Configuration

• Pin 2: Used as an ADC input to read battery voltage.

Telemetry Provided

• voltage: The current battery voltage (in volts).
• voltagePercent: The current battery percentage (calculated).

Telemetry Consumed

• None.

Commands Provided

• None.

Commands Consumed

• None.

Additional Information

• Battery voltage is checked every 5 seconds.
• The device enters light sleep for 10 minutes if the battery percentage is below 90% and it has been running for more than 2 minutes.
• The ADC is configured with an attenuation of ADC.ATTN_11DB to support a full range of 3.3V.
• The device reboots automatically if it has been running for more than 100 hours.
