Function Documentation

int can_dll_dispatch_bus_off ( kernel_pid_t pid )

Dispatch RX error from a device.

Dispatch RX error from a device to receivers threads which have subscribed to frames on that interface

Parameters

[in] pid the device thread pid

int can_dll_dispatch_rx_frame	(	can_frame_t *	frame,
		kernel_pid_t	pid )

Dispatch a received frame.

This function is used to send a message to the DLL thread when a frame is received from the device identified by its pid

Parameters

[in]	frame	the received frame
[in]	pid	the pid of the receiver device

int can_dll_dispatch_tx_conf ( can_pkt_t * pkt )

Dispatch a tx confirmation.

This function is used to send a message to the sender thread when the pkt has been sent correctly.

Parameters

[in] pkt the pkt which has been sent

int can_dll_dispatch_tx_error ( can_pkt_t * pkt )

Dispatch a tx error.

This function is used to send a message to the sender thread when the pkt has not been sent correctly

Parameters

[in] pkt the pkt which has not been sent correctly

int can_dll_init ( void )

Initialize the CAN DLL.
