Enumeration Type Documentation

CtrlPin

enum class pca9685::CtrlPin : uint8_t

strong

Identifies the hardware control pins of the PCA9685.

Used with GpioSet() / GpioSetActive() / GpioSetInactive() to control the IC's dedicated GPIO pins through the I2cInterface.

The mapping from GpioSignal::ACTIVE / INACTIVE to physical HIGH / LOW is determined by the platform bus implementation:

• OE: Active-low (ACTIVE → physical LOW, outputs enabled)

Enumerator
OE	Output Enable (active-low on the physical pin)

GpioSignal

enum class pca9685::GpioSignal : uint8_t

strong

Abstract signal level for control pins.

Decouples the driver's intent from the physical pin polarity.

Enumerator
INACTIVE	Pin function is deasserted.
ACTIVE	Pin function is asserted.
