Enumeration Type Documentation

BNO085Interface

enum class BNO085Interface : uint8_t

strong

Identifies the host interface type that a CommInterface provides.

Returned by CommInterface::GetInterfaceType(). The BNO085 driver uses this value to guard which operations are valid at runtime:

• SH-2 mode (Begin, Update, EnableSensor, Dfu): requires I2C, SPI, or UART.
• RVC mode (BeginRvc, ServiceRvc, CloseRvc): requires UARTRVC.

The enum values also correspond to the BNO08x PS1/PS0 pin states that select the interface at boot time.

Enumerator
I2C	I2C bus (PS1=0, PS0=0). Supports SH-2 and DFU.
UARTRVC	UART in RVC mode (PS1=1, PS0=0). RVC frames only.
UART	UART in SH-2 mode (PS1=0, PS0=1). Supports SH-2 and DFU.
SPI	SPI bus (PS1=1, PS0=1). Supports SH-2 and DFU.
