These values are used to initialize hardware filters and masks. (See “Filtering” on page 29).

Compilation Options

//Start options

//#define WAKE_UP_PULSE

#define RUN_ON_START_UP

You may decide whether or not to include these options in the code.

If enabled:

– WAKE_UP_PULSE enables the cell to send a dominant bit when leaving Standby mode.

– RUN_ON_START_UP starts the cell in the Initialization function CAN_First_Init. If not en-

abled, make sure that a dominant bit detected on the bus can make the cell start. To do

this, complete the

CAN_Dominant_Bit_Reception_Notification() function in can_custom.c

in calling CAN_Switch_On.

//#define FILTERS_ENABLED

//#define INIT_FILTERS {}

These options are used for software filtering.

Select both of them if you want to use the feature.

If selected, enter the list of identifiers to be accepted between the curly braces as shown in

“Software Filter Configuration” on page 30.

Enabling one of the following options implies modifying the corresponding function in the

can_custom.c file:

//#define STATUS_CHANGE_NOTIFICATION

This option is used to monitor status changes (active/passive/bus-off). Setting this option will

change the priority order in which the interrupts are taken into account. The interrupts con-

cerning status change will be checked first, before considering reception and transmission in-

terrup ts. It will a lso allow co mpilation of the co rrespond in g notificatio n function s

(CAN_Bus_Passive_Notification, CAN_Bus_Active_Notification, CAN_Bus_Off_Notification).

To use the Error Notification functions (called when an Error IT is received), enable:

//#define DEBUG
