variable active_driver

Pointer to the currently active CAN driver (set by mock_can_init) 

const can_driver_t* active_driver;

Public Functions Documentation

function can_receive

Receives a CAN frame using the active CAN driver. 

int can_receive (
    uint32_t * id,
    uint8_t * data,
    uint8_t * len
)

Parameters:

  • id Pointer to store the received CAN ID.
  • data Pointer to buffer to store the received CAN data.
  • len Pointer to variable to store the length of the received CAN data.

Returns:

int 0 on success, -1 if the queue is empty or if the driver is not set.

function can_send

Sends a CAN frame using the active CAN driver. 

int can_send (
    uint32_t id,
    const uint8_t * data,
    uint8_t len
)

Parameters:

  • id CAN ID to send.
  • data Pointer to the CAN data to send.
  • len Length of the CAN data to send.

Returns:

int 0 on success, -1 on failure (e.g., if the driver is not set or if send fails).

function can_set_driver

Sets the active CAN driver to be used by the ISO-TP implementation. 

void can_set_driver (
    const can_driver_t * driver
)

Parameters:

  • driver Pointer to the CAN driver to set as active.
