The SPI Transmission configuration parameters.

结构体成员变量说明

◆ current_tx_fragment

spi_tx_fragment_t* spi_tx_state::current_tx_fragment

Current TX fragment being transmitted.

◆ current_tx_fragment_pos

uint32_t spi_tx_state::current_tx_fragment_pos

Index of the current position of the next byte to be transmitted in the current TX fragment current_tx_fragment_pos == 0 means the first byte is yet to be sent for transmission

◆ fragment_buffer

spi_tx_fragment_t spi_tx_state::fragment_buffer[4]

Fragments buffer pointer.

◆ fragments_to_process

uint16_t spi_tx_state::fragments_to_process

Number of fragments to process including the current one.

◆ free_tx_fragment

spi_tx_fragment_t* spi_tx_state::free_tx_fragment

The unused TX fragment admin blocks available for re-use/freeing.

◆ tx_callback

spi_tx_callback_t spi_tx_state::tx_callback
