Before using a CAN message object, call the function ARM_CAN_ObjectGetCapabilities to verify the available features. Send CAN message or send Remote Frame or set CAN message to be sent automatically on reception of matching Remote Frame on the message object.Ĭallback function that signals a message transfer or a received message overrun.Įach CAN message object may have different capabilities. Read received message from the message object. Retrieves message object capabilities such as receive, transmit, Remote Frame automatic handling and CAN Message Filtering.Īllows to set-up CAN ID filtering for the message object.Īllows to configure the message object for receive, transmit or Remote Frame automatic handling. CAN message objects are addressed with the functions listed below, whereby the parameter obj_idx addresses an individual object. The number is encoded in the structure ARM_CAN_CAPABILITIES in the data field num_objects. The function ARM_CAN_GetCapabilities returns the maximum number of available CAN message objects. The number of available CAN message objects depends on the CAN peripheral. The CMSIS-Driver for the CAN interface provides multiple CAN message objects, which can be seen as individual communication channels. The CAN Driver supports multiple nodes, which are able to send and receive messages, but not simultaneously. The CAN Driver API defines a CAN interface for middleware components.
Support for CAN FD depends on the hardware. Wikipedia offers more information about the CAN Bus.ĬAN 2.0B** Every CAN CMSIS-Driver supports the CAN 2.0B standard CAN FD: CAN with Flexible Data Rate introduced in 2012 (released April 17th, 2012).

1991) which is now superseded by ISO 11898-1. CAN 2.0B: CAN Specification 2.0B (released Sep.The CAN Driver API allows to implement CAN Interfaces that conform to the CAN specifications available from BOSCH: Devices are connected to the bus through a host processor, a CAN controller, and a CAN transceiver. The node may also be a gateway allowing a standard computer to communicate over a USB or Ethernet port to the devices on a CAN network. The complexity of the node can range from a simple I/O device up to an embedded computer with a CAN interface and sophisticated software.
CAN is a message-based protocol, designed originally for automotive applications, but meanwhile used also in many other surroundings.

The Controller Area Network Interface Bus (CAN) implements a multi-master serial bus for connecting microcontrollers and devices, also known as nodes, to communicate with each other in applications without a host computer.
