Detailed Description

Stream Link Interface HW driver source file.

Function Documentation

◆ neorv32_slink_available()

int neorv32_slink_available ( void )

Check if stream link interface was synthesized.

Returns: 0 if SLINK was not synthesized, 1 if SLINK is available.

◆ neorv32_slink_get()

uint32_t neorv32_slink_get ( void )

inline

Read data from RX link (non-blocking)

Returns: Data received from link.

◆ neorv32_slink_get_rx_fifo_depth()

int neorv32_slink_get_rx_fifo_depth ( void )

Get FIFO depth of RX link.

Returns: FIFO depth of RX link (1..32768).

◆ neorv32_slink_get_tx_fifo_depth()

int neorv32_slink_get_tx_fifo_depth ( void )

Get FIFO depth of TX link.

Returns: FIFO depth of TX link (1..32768).

◆ neorv32_slink_put()

void neorv32_slink_put ( uint32_t tx_data )

inline

Write data to TX link (non-blocking)

Parameters

[in] tx_data Data to send to link.

◆ neorv32_slink_rx_clear()

void neorv32_slink_rx_clear ( void )

Clear RX FIFO.

◆ neorv32_slink_rx_status()

int neorv32_slink_rx_status ( void )

Get RX link FIFO status.

Returns: FIFO status NEORV32_SLINK_STATUS_enum.

◆ neorv32_slink_setup()

void neorv32_slink_setup ( uint32_t irq_config )

Reset, enable and configure SLINK.

Parameters

[in] irq_config Configure RX and TX interrupt conditions (NEORV32_SLINK_CTRL_enum).

◆ neorv32_slink_tx_clear()

void neorv32_slink_tx_clear ( void )

Clear TX FIFO.

◆ neorv32_slink_tx_status()

int neorv32_slink_tx_status ( void )

Get TX link FIFO status.

Returns: FIFO status NEORV32_SLINK_STATUS_enum.
