CANpie FD - Protocol Stack

The CAN driver CANpie FD (Controller Area Network Programming Interface Environment) is an open interface for the development of CAN-based applications. The CAN driver forms the basis for higher layer protocols (CANopen / J1939) and may be used for manufacturer-specific CAN communication between embedded systems. CANpie FD is avaliable for a wide range of microcontrollers (more than 160 at the moment). A variety of configuration options facilitates adjustment to individual target systems. The CAN physical layer (data link layer) comprises two protocols: the classical CAN standard and CAN FD. The protocols are described in the ISO 11898-1:2015 specification. The CANpie FD API defines 19 functions to allow manufacturer independend access to the CAN controller to entirely support ISO specifications. The API is based on the concept of dedicated message buffers (mailboxes) in combination with acceptance masks to minimize the application
