Detailed Description

ESP32 UART CommInterface for BNO08x RVC mode.

Reads raw UART bytes that the BNO085 driver's internal RVC frame parser processes. The driver calls Read() one byte at a time to accumulate and validate 19-byte RVC frames.

GpioSet()

void Esp32UartRvcBus::GpioSet ( bno08x::CtrlPin pin, bno08x::GpioSignal signal )

inlinenoexcept

Set a control pin to the specified signal state (required by CommInterface)

Maps GpioSignal to physical level based on pin polarity:

• RSTN: active-low (ACTIVE → GPIO 0, INACTIVE → GPIO 1)
• BOOTN: active-low (ACTIVE → GPIO 0, INACTIVE → GPIO 1)
• WAKE/PS0/PS1: not wired in this implementation (no-op)

Parameters

pin	Which control pin to drive
signal	ACTIVE to assert, INACTIVE to deassert

Open()

bool Esp32UartRvcBus::Open ( )

inlinenoexcept

Read()

int Esp32UartRvcBus::Read ( uint8_t * data, uint32_t length )

inlinenoexcept

Read raw bytes from UART.

The BNO085 driver calls this one byte at a time to feed the RVC frame parser. Non-blocking: returns 0 immediately if no data available.

Write()

int Esp32UartRvcBus::Write ( const uint8_t * , uint32_t  )
