Function Documentation

FlushRxdr()

void anonymous_namespace{StmI2c.cpp}::FlushRxdr ( I2C_HandleTypeDef *  hi2c )

noexcept

Drop a stale RX byte so the next Mem_Read cannot splice a prior payload.

FlushTxdr()

void anonymous_namespace{StmI2c.cpp}::FlushTxdr ( I2C_HandleTypeDef *  hi2c )

noexcept

Mirror of HAL private I2C_Flush_TXDR — clear sticky TXIS before a new xfer.

HalXferOk()

bool anonymous_namespace{StmI2c.cpp}::HalXferOk ( I2C_HandleTypeDef *  hi2c, uint32_t  status  )

noexcept

PrepareMasterXfer()

void anonymous_namespace{StmI2c.cpp}::PrepareMasterXfer ( I2C_HandleTypeDef *  hi2c )

noexcept

Prepare a READY master for a new blocking transfer.

RecoverI2cAfterError()

void anonymous_namespace{StmI2c.cpp}::RecoverI2cAfterError ( I2C_HandleTypeDef *  hi2c )

noexcept

Soft-recover STM32H7 I2C after NACK/timeout so the next xfer can proceed.
