CAN_init

#include <rtx_can.h>

CAN_ERROR CAN_init (
    U32 ctrl,         /* CAN Controller */
    U32 baudrate);    /* Baudrate */

The CAN_init function sets the baudrate for the CAN controller specified by ctrl. The baudrate may be a value from 10,000-1,000,000 (10 Kbps to 1 Mbps).

This function may be invoked one or more times.

• The first invocation of CAN_init configures hardware used by the CAN driver, initializes common resources including mailboxes used as message FIFOs, and sets the CAN bus baudrate.
• Subsequent invocations initialize mailboxes used as message FIFOs and set the CAN bus baudrate.

The CAN_init function is part of RL-CAN. The prototype is defined in RTX_CAN.h.

The CAN_init function returns one of the following manifest constants.

• CAN_OK
  Success.
• CAN_MEM_POOL_INIT_ERROR
  Indicates the memory pool was incorrectly initialized.
• CAN_BAUDRATE_ERROR
  Indicates that the communication speed was incorrectly initialized.
