Detailed Description

Built-in animation engine for SBK_BarMeter-based LED displays.

This file defines the SBK_BarMeterAnimations template class, which provides a rich set of built-in animation sequences for LED bar meters. It supports dynamic animations like filling, bouncing, signal tracking, block emissions, random pixel updates, and more.

Compatible with any SBK_BarMeter<DriverT> instance, this class integrates directly with SBK_BarDrive through its .animations() accessor.

Highlights:

• Looping and one-shot animations
• Direction and logic inversion controls
• Live signal tracking and pointer rendering
• Block-based animations with emission control
• BPM-synchronized beat pulse effect
• Chainable animation starter functions
• Pixel state aware when SBK_TRACK_PIXEL_STATE is defined

Template Parameters

BarMeterT

A specific instantiation of SBK_BarMeter (e.g., SBK_BarMeter<SBK_MAX72xxSoft>)
