Detailed Description
the class to work on the CAN controller interface
Gemäß dem AUTOSAR Gedanken abstrahiert das CAN Interface die gesamte CAN Hardware. Es wird also später auch nur ein CanIf Objekt geben.
Genauso wird diese CanIf Objekt global angelegt sein.
- Todo:
- es braucht eine Absicherung auf nur ein Objekt
Constructor & Destructor Documentation
◆ CanIf()
| CanIf::CanIf | ( | ) |
Standard constructor will do a connection to the precompile configuration
◆ ~CanIf()
| CanIf::~CanIf | ( | ) |
Destructor shouldn't called on an embedded system
Member Function Documentation
◆ RxIndication()
|
virtual |
The service CanIf_RxIndication() is implemented in CanIf and called by CanDrv after a CAN L-PDU has been received.
Implements ComIf.

we need a handle to hold the information for the bxCAN controller
- Todo:
- there are STM controller with three CAN controller too!!!
We create a list with CAN message headers for fast access sorted by the CanIf_txPduIdType
we use the STM-CAN-Message-Headers for fast copy during tx. Maybe we change this later on pre compiled linking that could be on FLASH
