Enumeration Type Documentation

CtrlPin

enum class bno08x::CtrlPin : uint8_t

strong

Identifies the hardware control pins of the BNO08x.

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

The mapping from GpioSignal::ACTIVE / INACTIVE to physical HIGH / LOW is determined by the platform bus implementation, based on the board's active-level design:

• RSTN: Active-low (ACTIVE → physical LOW, asserts reset)
• BOOTN: Active-low (ACTIVE → physical LOW, enters bootloader)
• WAKE: Active-low (ACTIVE → physical LOW, wakes sensor from suspend)
• PS0: Active-high (ACTIVE → physical HIGH, PS0 = 1)
• PS1: Active-high (ACTIVE → physical HIGH, PS1 = 1)

Enumerator
RSTN	Hardware reset (active-low on the physical pin)
BOOTN	Bootloader entry (active-low on the physical pin)
WAKE	Wake from suspend, SPI mode only (active-low on the physical pin)
PS0	Protocol select bit 0 (active-high on the physical pin)
PS1	Protocol select bit 1 (active-high on the physical pin)

GpioSignal

enum class bno08x::GpioSignal : uint8_t

strong

Abstract signal level for control pins.

Decouples the driver's intent from the physical pin polarity. The platform bus implementation translates ACTIVE / INACTIVE to the correct electrical level for each pin.

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