Detailed Description

Driver classes to handle a specific CAN controller module.

Enumeration Type Documentation

strong

CAN Controller State Machine

Enumerator
CS_Uninit	for hardware init we will be in
CS_Started	This is the working state
CS_Stopped	the CAN controller is ready to work, but does not participate on the bus
CS_Sleep	the CAN controller is in sleep mode

strong

CAN module state machine is very simple.

the controller holds there own state machine with CanControllerStates

Enumerator
Uninit	the module is without configuration
Ready	the configuration is loaded

Definition at line 226 of file Can.h.

const ComIf* ptr2ComIf

To hold the callback function pointers of the CanIf module

Todo:: we should bring this inside the CanDrv object, we need it outside because of use in ISR

To hold the callback function pointers of the CanIf module
