depends on DT_HAS_ST_STM32_CAN_ENABLED
help
Enable STM32 CAN Driver.
Tested on STM32F0, STM32F4, STM32L4 and STM32F7 series.

default 14
range 0 28
help
Defines the maximum number of filters with standard ID (11-bit)
that can be added by the application.
One standard ID filter with mask occupies 1/2 of the 14 available
filter banks.
The following equation determines the maximum total number of
filters:
CAN_MAX_STD_ID_FILTER + CAN_MAX_EXT_ID_FILTER * 2 <= 28
config CAN_MAX_EXT_ID_FILTER
int "Maximum number of ext ID filters"
default 7
range 0 14
help
Defines the maximum number of filters with extended ID (29-bit)
that can be added by the application.
One extended ID filter with mask occupies 1 of the 14 available
filter banks.
The following equation determines the maximum total number of
filters:
CAN_MAX_STD_ID_FILTER + CAN_MAX_EXT_ID_FILTER * 2 <= 28
