CANMSP432E4.h File Reference

Detailed Description

CAN driver implementation for a MSP432E4 CAN controller.

============================================================================

The CAN header file should be included in an application as follows:

#include <ti/drivers/CAN.h>
#include <ti/drivers/can/CANMSP432E4.h>

Stack requirements

The CANMSP432E4 driver is a (ring) buffered driver that stores data it may

have already received in a user-supplied background buffer.

#include <stdbool.h>
#include <stddef.h>
#include <stdint.h>
#include <ti/devices/msp432e4/inc/msp432.h>
#include <ti/devices/msp432e4/driverlib/gpio.h>
#include <ti/devices/msp432e4/driverlib/pin_map.h>
#include <ti/drivers/dpl/ClockP.h>
#include <ti/drivers/dpl/HwiP.h>
