Enumeration Type Documentation

BarDirection

enum class BarDirection : uint8_t

strong

Direction of bar fill or animation progression.

Used to control the rendering orientation of bar animations and pixel updates.

• FORWARD: From first segment to last.
• REVERSE: From last segment to first.

Enumerator
FORWARD	From first segment to last.
REVERSE	From last segment to first.

Definition at line 102 of file SBK_BarDrive.h.

MatrixPreset

enum class MatrixPreset

strong

Enables built-in animation support for SBK_BarDrive.

Define this macro before including SBK_BarDrive.h to activate the SBK_BarMeterAnimations system. Without this definition, animation methods like .animations() will not be available, reducing flash and RAM usage for minimal builds.

Preset types for common matrix-style bar meter hardware configurations.

Defines built-in mapping presets for SBK matrix-type bar meters. These presets simplify the initialization of the SBK_BarMeter class by providing predefined segment-to-row/column mappings, avoiding the need for manual setup.

Enumerator
NONE	No preset selected; manual segment mapping is required.
SBK_BarMeter_SK28	Alias for SBK BarMeter SK28, uses the BL28_3005SK preset internally.
SBK_BarMeter_SA28	Alias for SBK BarMeter SA28, uses the BL28_3005SA preset internally.
BL28_3005SK	Native mapping for BL28-3005SK (4 anodes × 7 cathodes), common cathode.
BL28_3005SA	Native mapping for BL28-3005SA (7 anodes × 4 cathodes), common anode.
