Detailed Description

CRTP adapter mapping BaseSpi::Transfer onto at25040::SpiInterface.

Constructor & Destructor Documentation

At25040SpiAdapter()

At25040SpiAdapter::At25040SpiAdapter ( BaseSpi &  spi )

inlineexplicitnoexcept

Parameters

spi	Host SPI device; must outlive this adapter.

Member Function Documentation

delay_us()

void At25040SpiAdapter::delay_us ( uint32_t  us )

inlinenoexcept

Optional driver hook: sleep between RDSR polls of the write cycle.

Parameters

us	Microseconds (the driver asks for 100 µs).

transfer()

bool At25040SpiAdapter::transfer ( const uint8_t *  tx, uint8_t *  rx, std::size_t  len, uint32_t  timeout_ms  )

inline

Full-duplex transfer used by the AT25040 driver.

Parameters

tx	Transmit buffer (may be nullptr to clock zeros).
rx	Receive buffer (may be nullptr to discard).
len	Byte count.
timeout_ms	Transfer deadline.

Returns

true when BaseSpi::Transfer reports success.
