3.2.1.2 Software Filters
Once the SOFTWARE_FILTERS option is defined in can_custom.h and the list of filters is
completed, the compiler will define and initialize a structure containing the data.
typedef struct{
u8 array_size;
u16* filters_array;
}CAN_Filters_Array;
This structure is composed of the size of the array, automatically calculated at compilation,
and of an array of 2-byte long numbers.
Consequently, the following constants are defined in the can.c file:
const u16 i_filters[]=INIT_FILTERS;
const CAN_Filters_Array CAN_filters={
As we can see, they are immediately initialized. Size_Of_Words_Array is a macro and i_filters
is the array filled with your data.
You can access the i_filters array, declared as extern const in can.h.
3.2.1.3 Enum Types
They are used as return values for some internal routines.
