Detailed Description

CRTP adapter connecting BaseSpi + CONVST/DRDY GPIO to the ADS9324 driver.

Implements both ads9324::SpiInterface and ads9324::HostInterface so a single object can be passed as the driver's SpiType and HostType.

Note

DelayUs is a calibrated busy loop (no RTOS microsecond delay in hf-core). DelayMs uses os_delay_msec.

Warning

SPI Transfer return codes are currently ignored — the driver treats config writes as infallible.

Constructor & Destructor Documentation

Ads9324SpiHostAdapter()

Ads9324SpiHostAdapter::Ads9324SpiHostAdapter ( BaseSpi &  spi, BaseGpio *  convst, BaseGpio *  drdy  )

noexcept

Bind SPI and conversion pins.

Parameters

spi	SPI device (CS owned by BaseSpi).
convst	CONVST GPIO (may be nullptr; handler init will then fail).
drdy	Optional DRDY GPIO; nullptr selects timed CONVST fallback.

Member Function Documentation

ConvstWrite()

void Ads9324SpiHostAdapter::ConvstWrite ( bool  high )

noexcept

Drive CONVST.

Parameters

high	true = SetActive() (CONVST high), false = SetInactive().

DelayMs()

void Ads9324SpiHostAdapter::DelayMs ( uint32_t  ms )

noexcept

Sleep milliseconds via os_delay_msec (chunked at 65535 ms).

Parameters

ms	Delay duration.

DelayUs()

void Ads9324SpiHostAdapter::DelayUs ( uint32_t  us )

noexcept

Busy-wait microseconds (nested volatile loop).

Parameters

us	Delay duration.

DrdyRead()

bool Ads9324SpiHostAdapter::DrdyRead ( )

noexcept

Sample DRDY.

Returns

IsActive() of the DRDY pin, or true when DRDY is not wired.

HasDrdy()

bool Ads9324SpiHostAdapter::HasDrdy ( ) const

noexcept

Whether a DRDY GPIO was supplied.

Returns

false → driver uses ADS9324_CFG::CONV_FALLBACK_US.

transfer()

bool Ads9324SpiHostAdapter::transfer ( const uint8_t *  tx, uint8_t *  rx, std::size_t  len  )

noexcept

Full-duplex SPI transfer (CRTP dispatch target).

Parameters

tx	Transmit buffer, or nullptr to clock zeros.
rx	Receive buffer, or nullptr to discard MISO.
len	Byte count (3 for config; N×2 or N×3 for conversion).

Returns

true when the bytes were clocked, false on a BaseSpi error.
