This task involves displaying the current battery percentage on screen, updating dynamically as the battery charges or discharges.
Implementation Guidance
– Retrieve battery percentage data using the AXP20X driver, which provides direct access to battery statistics from the AXP202
– Pass the retrieved value into a drawBatterySymbol() style display function to render it visually
– Ensure battery percentage updates don’t interfere with or overwrite other active display operations
